3What this role really is

You'll build and optimise generative AI systems, working hands-on with large language models and making sure they work in the real world. It involves turning AI concepts into working product features.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Building custom model architectures, fine-tuning LLMs, implementing RAG pipelines, and developing evaluation scripts. You'll be living in Python.

LLM Frameworks (LangChain, LlamaIndex) Advanced

Building applications using these frameworks based on documented patterns, implementing basic RAG pipelines, and developing agentic workflows for specific features.

Vector Databases (Pinecone, Weaviate, Milvus) Intermediate

Performing CRUD operations, similarity searches, and optimising indexing strategies for specific RAG applications. You'll be managing the knowledge base for our LLMs.

Cloud AI Platforms (AWS SageMaker, Google Vertex AI, Azure OpenAI Service) Intermediate

Deploying and running models using managed services, managing fine-tuning jobs, and using platform SDKs for basic MLOps tasks. We tend to use AWS, but familiarity with others is a bonus.

Experiment Tracking (Weights & Biases, MLflow) Advanced

Logging metrics, parameters, and artefacts for your experiments, comparing runs, and reproducing results to ensure scientific rigour in model development.

Containerisation (Docker, Kubernetes) Intermediate

Using Docker to containerise your generative AI applications and manage dependencies. You'll be deploying these containers, probably onto Kubernetes, so understanding how that works is key.

Version Control (Git) Expert

Collaborating on code, managing branches, resolving conflicts, and maintaining a clean and traceable codebase for all AI projects.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Technical Approach for a New Feature Proposes options, requires full review and approval by Senior Engineer. Proposes and justifies a specific approach, consults with Senior Engineer, proceeds with agreement. Can independently choose specific models/libraries for well-defined tasks. Defines the overall technical approach and architecture, consults with Lead/Staff Engineer for strategic alignment, makes final technical decisions within project scope.
Production Deployment of a Model Prepares deployment artefacts under close supervision, deployment executed by Senior Engineer. Independently deploys minor model updates or new, small features after peer review and manager approval. Requires sign-off for major changes. Leads deployment strategy for major systems, approves deployment plans for projects, accountable for production stability.
GPU Resource Allocation for Training Requests specific resources for defined tasks, approved by Senior Engineer. Estimates and requests resources for project-level training runs (e.g., a few A100 hours), requires manager approval for significant or long-running jobs. Manages resource allocation across multiple projects, optimises usage, consults with Lead/Staff on large-scale cluster needs.
Vendor/Tool Selection (e.g., new Vector DB) Researches options and provides summaries to Senior Engineer. Evaluates 2-3 options for a specific project need, makes a recommendation with a clear justification, requires manager approval. Evaluates and recommends strategic tools/vendors for a workstream, budget approval up to £5K, consults with Lead/Staff for larger commitments.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Model Inference Latency (P95)
The time it takes for our generative AI models to respond to a request.
Target · Maintain P95 latency below 500ms for user-facing features.

If a user asks a question, we want the AI to answer within half a second, 95% of the time. If it's consistently hitting 700ms, that's a problem we need to fix.

Task-specific Evaluation Score
How accurately and appropriately our models generate content for specific tasks (e.g., summarisation, code generation, question answering).
Target · Achieve 85% accuracy/relevance on internal evaluation benchmarks for new features.

For our new content generation tool, if 8 out of 10 outputs are considered 'good' by human evaluators, we're hitting our target. If it drops to 6, we know something's off.

Deployment Frequency
How often you're able to push new or updated generative AI features/models to production.
Target · Deploy new model versions or feature updates at least once every two weeks.

If we're only pushing code once a month, we're moving too slowly. The goal is to iterate quickly, so getting new improvements out every fortnight is key.

Cost-per-inference Optimisation
The computational cost associated with each model request.
Target · Reduce average cost-per-inference by 10% quarter-over-quarter without sacrificing quality.

If each API call to our LLM costs £0.01, we're looking to get that down to £0.009 next quarter. Small savings add up quickly when you're running millions of inferences.

Code Quality & Maintainability
How clean, well-documented, and easy-to-understand your code is, making it simple for others to pick up or debug.
  • Positive feedback in code reviews, fewer bugs reported in your modules, clear and concise documentation (docstrings, READMEs), and your solutions being adopted as patterns by others.
Problem-Solving Effectiveness
Your ability to diagnose and fix issues with generative AI models, especially when things go wrong in unexpected ways.
  • Successfully debugging complex model behaviours (e.g., hallucinations, unexpected outputs), identifying root causes quickly, and proposing robust solutions that prevent recurrence. You're the person others come to when they're stuck on a tricky model issue.
Collaboration & Knowledge Sharing
How well you work with other teams and share what you've learned, helping everyone else get better at GenAI.
  • Actively participating in team discussions, offering helpful advice in code reviews, contributing to internal knowledge bases or wikis, and helping junior team members get unstuck. You're seen as someone who makes the team smarter.
Proactive Issue Identification
Spotting potential problems with models or pipelines before they become big, user-facing issues.
  • Raising concerns about data drift, potential model biases, or scaling challenges before they impact production. You're not just reacting to fires
  • you're trying to prevent them.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Hard, Novel Technical Problems

You'll spend your days grappling with tricky issues like reducing model hallucinations, optimising inference speed for a new architecture, or figuring out how to get a RAG pipeline to work reliably with really messy data. It's a constant puzzle.

Being given a challenge like 'our summarisation model is too slow and sometimes makes things up' and being able to dive deep, experiment with different PEFT methods, and see a tangible improvement.

Direct Impact on Product & Users

Your code and models won't just sit in a research paper; they'll be integrated into our products, and you'll see users interacting with them. You'll get feedback (good and bad) and know your work is making a difference.

Launching a new AI-powered feature and seeing positive customer reviews about how much easier it makes their work, knowing you built the core AI engine behind it.

Continuous Learning in a Rapidly Evolving Field

You'll be expected (and encouraged) to spend time exploring new models, frameworks, and research papers. This isn't a static role; you'll constantly be learning and applying the latest techniques.

Spending a Friday afternoon experimenting with the latest open-source LLM or a new vector database, then sharing your findings with the team on Monday.

What frustrates people
  • The unreasonable effectiveness of 'magic': Stakeholders often treat LLMs as magical black boxes, leading to wildly unrealistic expectations and feature requests that defy the current laws of AI physics.
  • The data janitor reality: 80% of building a good RAG system is the unglamorous work of cleaning, chunking, and preparing messy, unstructured source documents.
  • Chasing a moving target: You spend three months fine-tuning a model for a specific task, only for GPT-5 to be released, making your work obsolete overnight. The pace is relentless.
  • The GPU budget scrutiny: Your requests for more A100/H100 compute are scrutinised by finance like a capital expense, forcing you to justify every pound spent on experimental model training.
What this role does not give you
  • A slow, predictable pace with clearly defined, unchanging requirements.
  • A role where you only work on greenfield projects; there's plenty of existing code to maintain and improve.
  • A role where you're handed perfectly clean datasets; you'll be doing a lot of data wrangling.
  • A role where every single model or feature you build makes it to production; some experiments just won't pan out.

8Who you work with

This role directly impacts our product's intelligence and our ability to deliver innovative features. Your work will shape how our customers interact with our platform, driving user engagement and, ultimately, our market position. Get it right, and we're seen as leaders; get it wrong, and we're just another company dabbling in AI.

Inside the business
  • Product Managers (for feature requirements)
  • Software Engineering Teams (for integration)
  • Data Scientists (for model insights and evaluation)
  • UX/UI Designers (for user experience of AI features)
Outside the business
  • Cloud AI Platform Vendors (for technical support)
  • Open-source AI Communities (for learning and contribution)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • Solid programming skills in Python, including experience with data structures, algorithms, and object-oriented programming.
  • A good grasp of machine learning fundamentals: supervised/unsupervised learning, model evaluation metrics, bias-variance trade-off.
  • Practical experience with at least one major deep learning framework (PyTorch or TensorFlow) for building and training models.
  • Familiarity with cloud platforms (AWS, GCP, or Azure) for deploying and managing ML workloads.
  • Experience with version control systems, specifically Git, in a collaborative team environment.
  • A genuine curiosity about generative AI and a track record of self-learning in this rapidly evolving field (e.g., personal projects, online courses, contributions to open source).

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced RAG Optimisation & Hybrid Search

Basic RAG is becoming standard, but getting truly reliable, high-quality retrieval requires going beyond simple vector search. Hybrid approaches and more sophisticated re-ranking will be essential to tackle complex information retrieval challenges.

Hybrid search (vector + keyword) · Re-ranking models · Graph-based RAG · Self-correcting RAG

  • This month: Implement a basic hybrid search (e.g., BM25 + vector search) in one of our existing RAG pipelines.
  • Next quarter: Experiment with a re-ranking model to improve the quality of retrieved documents for a tricky use case.
  • Month 3-6: Explore the concepts of knowledge graphs and how they could be integrated into our RAG architecture for more complex queries.
  • Ongoing: Stay updated on the latest research in information retrieval and RAG architectures.

Quick win: Start by adding a simple keyword search component to an existing vector search, then measure if it improves retrieval quality.

Multi-modal Generative AI

The world isn't just text. Models that can understand and generate across text, images, audio, and video are becoming increasingly powerful and will unlock entirely new product capabilities. You'll need to think beyond just words.

Vision-Language Models (VLMs) · Image generation (Stable Diffusion, DALL-E) · Audio generation & speech-to-text · Cross-modal embeddings

  • This month: Experiment with an open-source VLM (e.g., LLaVA) or an image generation model (e.g., Stable Diffusion) in a personal project.
  • Next quarter: Propose a small internal project where multi-modal AI could add value (e.g., generating image captions, summarising video content).
  • Month 3-6: Dive into the architectures of multi-modal models, understanding how different modalities are integrated and processed.
  • Ongoing: Follow research in multi-modal AI and explore relevant datasets.

Quick win: Try using an existing multi-modal API (like GPT-4V) to analyse images or videos and extract insights. It's a great way to see the potential.

11Staying current once you are in

What people here do to keep up
  • Actively participating in online communities (e.g., Hugging Face forums, relevant subreddits, Discord servers) focused on generative AI.
  • Contributing to open-source generative AI projects, even small bug fixes or documentation improvements.
  • Attending industry conferences or local meetups focused on AI, machine learning, or natural language processing.
  • Completing advanced online courses or specialisations in areas like MLOps, advanced deep learning architectures, or multi-modal AI.
  • Maintaining a personal portfolio of generative AI projects on GitHub, showcasing your hands-on skills and curiosity.

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Advanced Prompt Engineering & Agentic Workflows

Simply writing a good prompt isn't enough anymore. As LLMs become more capable, the real value comes from orchestrating them into complex agents that can reason, plan, and execute multi-step tasks autonomously. This is where the big productivity gains (and challenges) will be.

  • Multi-agent systems
  • Tool use & function calling
  • Self-correction & reflection
  • Memory management for agents

Cost-Aware Model Selection & Optimisation

As GenAI scales, compute costs can skyrocket. Knowing how to pick the right model (open-source vs. proprietary, small vs. large) for a specific task, and then optimising its inference and training costs, will become absolutely critical for business viability.

  • Tokenomics & API pricing models
  • Quantisation & distillation
  • Batching & parallelisation
  • Benchmarking cost vs. quality

Working with AI

Where AI is starting to help

Let's be real, a lot of engineering work involves repetitive tasks, boilerplate code, and sifting through mountains of information. But what if you could offload some of that grunt work to AI? That's exactly what we're doing here at Zavmo.

As a Generative AI Engineer, you're not just building AI; you'll be using AI to build AI. We're committed to giving you the best tools to make your job more efficient, more creative, and frankly, more enjoyable. Imagine cutting down on the tedious bits and focusing on the really interesting, challenging problems.

Boilerplate Code Generation

Use a code-generation model like GitHub Copilot or similar tools to instantly create data loading scripts, model class skeletons, unit tests, and even complex API integrations. This means less time writing repetitive code and more time on core logic and innovation.

Research Paper Summariser

Feed the latest ArXiv papers, technical blogs, or internal documentation into an LLM to get concise summaries of key innovations, methodologies, and results. Stay current with the rapidly evolving GenAI landscape without having to read every 20-page paper in full detail.

Interactive Debugging Assistant

Paste complex error messages, confusing code blocks, or even a tricky prompt into a chat interface and ask an LLM to explain potential causes, suggest fixes, or refactor the code for clarity. It's like having a senior engineer on standby 24/7.

Automated Documentation Writer

Use an AI tool to automatically generate docstrings, README files, API documentation, and even internal wikis directly from your code. Ensure your projects are always well-documented without the manual grind, freeing you up for more impactful work.
