3What this role really is

A Lead Synthetic Data Engineer designs how synthetic data is generated, validated and used across an organisation.

4What you'd actually use

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

Python (PyTorch, Pandas, NumPy, Scikit-learn) Expert

Building custom generative models, data preprocessing, statistical validation, and scripting automation for data pipelines. Frankly, if you can't code in Python, this role isn't for you.

Synthetic Data Platforms (Gretel.ai, YData Fabric, Tonic.ai) Advanced

Evaluating, selecting, and integrating commercial synthetic data platforms. You'll build custom connectors, fine-tune advanced model parameters, and compare platform capabilities to meet our needs.

Data Orchestration (Apache Airflow, Dagster) Advanced

Designing and building complex, multi-stage data generation and validation pipelines. You'll implement dynamic DAG generation and set standards for logging and alerting.

Cloud & Data Warehouse (AWS S3, SageMaker, Glue, Snowflake) Advanced

Designing the end-to-end cloud architecture for synthetic data, optimising compute costs (AWS Glue, Snowpark), and managing data residency and security policies within AWS and Snowflake.

Data Quality & Validation (Great Expectations, Evidently AI) Advanced

Creating new, complex 'Expectations' for data validation and using tools like Evidently AI to diagnose subtle statistical drift between synthetic and real datasets. You'll define our quality benchmarks.

Containerization & MLOps (Docker, Kubernetes, MLflow) Advanced

Designing and implementing MLflow projects for reproducible generation pipelines, integrating with Kubernetes for scaling, and mandating containerization for all production data services. This is about making things robust.

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 Architecture Design Follows existing patterns, escalates design choices. Proposes design for specific features, gets approval from senior. Designs complex systems within established patterns, consults Lead on cross-cutting concerns.
Tool/Platform Selection Uses approved tools, escalates requests for new tools. Researches and recommends tools for specific tasks, needs senior approval. Evaluates and proposes new tools for workstreams, gets Lead's approval.
Budget Allocation (within domain) No budget authority, raises needs to supervisor. Manages small project-specific compute costs, needs manager approval. Manages workstream-specific compute and tooling costs up to £5K, consults Lead.
Team Hiring & Performance Participates in interviews as a peer, no decision authority. Provides feedback on candidates, mentors junior peers informally. Interviews and provides strong recommendations, formally mentors 1-2 juniors.
Data Privacy Risk Assessment Identifies potential risks, escalates to senior. Assesses risks for specific datasets, proposes mitigation strategies. Designs and implements privacy-preserving techniques, consults Lead on complex cases.

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.

Synthetic Data Utility Score (TSTR)
The average performance of downstream ML models trained on synthetic data compared to those trained on real data.
Target · >90% of real data model performance

If our fraud detection model gets 95% accuracy on real data, a model trained on your synthetic data should achieve at least 85.5% accuracy (90% of 95%).

Data Provisioning Time Reduction
The average time it takes for a development team to get access to a new, high-fidelity synthetic dataset for a project.
Target · Reduce by 40% compared to previous manual methods

If it used to take 3 weeks to get a 'safe' dataset, your systems should get it down to around 1.5 weeks.

Privacy Compliance Audit Pass Rate
The percentage of synthetic datasets that pass internal and external privacy audits without major findings.
Target · 100% pass rate for critical datasets

Zero critical findings from our legal team or external auditors regarding re-identification risk in synthetic data used for production-adjacent testing.

Synthetic Data Platform Adoption
The number of distinct engineering or data science teams actively using your synthetic data platform for their projects.
Target · 5+ active teams within 12 months

Seeing the Product, ML, and QA teams for our three biggest products regularly pulling synthetic data from your platform.

Architectural Soundness & Scalability
Your synthetic data architectures are robust, well-documented, and can handle growing data volumes and complexity without falling over. They're also cost-effective.
  • Positive feedback from Data Platform and DevOps teams during architecture reviews. Minimal incidents related to synthetic data pipeline failures. Clear, up-to-date architectural diagrams. Cost-per-dataset generation trending downwards.
Technical Leadership & Mentorship
You're seen as the technical authority for synthetic data, guiding junior engineers and influencing technical decisions across the data organisation.
  • Junior engineers actively seek your advice. You're leading technical discussions in team meetings. Your code reviews are insightful and help others learn. You're presenting technical solutions to senior leadership and they're listening.
Stakeholder Trust & Collaboration
Product, Legal, and Security teams trust your judgment on synthetic data matters and proactively involve you in their planning.
  • You're invited to early-stage product planning meetings. Legal consults you before drafting new privacy policies related to data usage. Security relies on your expertise for data de-identification strategies. They'll actually come to you for advice, not just tell you what to do.
Innovation & Thought Leadership
You're bringing new ideas and technologies to the table, keeping our synthetic data capabilities at the forefront of the industry.
  • You're proposing and prototyping new generative models or privacy-enhancing technologies. You're sharing insights from academic papers or industry conferences. You're contributing to internal knowledge sharing sessions on emerging trends.

7Would you like it

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

What people enjoy
Solving Hard, Uncharted Problems

You get a real kick out of tackling problems where there isn't a clear answer in a textbook. Building a synthetic data platform means you're often inventing new ways to do things, especially when balancing utility and privacy. It's about pushing the boundaries of what's possible.

Spending a week prototyping a new tabular diffusion model because GANs aren't quite cutting it for a specific dataset, and then seeing it actually work better.

Making a Tangible Business Impact

You're not just building models in a vacuum; your work directly enables faster product development, safer data use, and helps us avoid significant privacy risks. Seeing your synthetic data being used by dozens of engineers to build new features is hugely rewarding.

Getting feedback from a Product Lead that their team launched a feature two weeks early because they had reliable synthetic data to test with, thanks to your platform.

Mentoring & Building Capability

You enjoy guiding junior engineers, helping them understand complex generative models, and seeing them grow. You're building a team and a lasting capability, not just delivering a single project.

Spending an afternoon walking a junior engineer through the nuances of debugging a PyTorch GAN, helping them unstick a problem they've been wrestling with for days.

What frustrates people
  • The 'Moving Target' Problem: Production database schema changes without proper communication, breaking your pipelines.
  • Compute Budget Battles: Constantly justifying GPU-intensive training costs against other priorities.
  • Debugging Black Boxes: Trying to figure out why a complex generative model is failing or producing bizarre outputs is often more art than science.
  • Legal & Compliance Hurdles: Navigating stringent, sometimes technically naive, requirements from legal teams who want zero risk, which can cripple data utility.
  • The 'Just Use Faker' Argument: Repeatedly educating stakeholders on the difference between simple fake data and statistically robust synthetic data.
  • The Uncanny Valley of Data: Synthetic data that looks good on the surface but has subtle flaws that cause downstream models to fail in unexpected ways, requiring deep, frustrating investigation.
What this role does not give you
  • A perfectly predictable, routine work schedule.
  • Guaranteed immediate adoption of every solution you build without extensive justification.
  • An environment free from technical debt or legacy systems (we've got some, like most places).
  • A role where you only focus on pure research without practical implementation challenges.
  • Complete autonomy over budget without needing to justify spend to senior leadership.

8Who you work with

This role directly shapes our ability to innovate safely and quickly. You'll be building the foundational capabilities that allow us to develop new products and features without compromising customer privacy. Your work will reduce our reliance on sensitive production data for development and testing, significantly de-risking our operations and accelerating our time-to-market for new initiatives. Frankly, without robust synthetic data, we're either slow or exposed to privacy risks.

Inside the business
  • Head of Data Science
  • Product Engineering Leads
  • Legal & Compliance Team
  • Cyber Security Team
  • Data Platform Engineering
Outside the business
  • Synthetic Data Platform Vendors (e.g., Gretel.ai, Tonic.ai)
  • Industry Privacy Experts
  • Open-source communities for generative models

9What you need before you start

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

  • Proven experience (8+ years) as a Data Engineer, Machine Learning Engineer, or Data Scientist, with a significant focus on data generation or privacy-enhancing technologies.
  • Demonstrable experience leading technical projects or small engineering teams, including mentoring junior colleagues.
  • A strong portfolio or track record of designing, building, and deploying scalable data pipelines and/or machine learning systems in a production environment.
  • Deep expertise in Python and its data science ecosystem (PyTorch/TensorFlow, Pandas, NumPy, Scikit-learn).
  • Solid understanding of cloud platforms (AWS preferred) and data warehousing concepts (Snowflake, Databricks, etc.).
  • A degree in Computer Science, Statistics, Mathematics, or a related quantitative field, or equivalent practical experience. We care more about what you can do than where you went to university.

10What to practise next

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

Advanced Diffusion Models & Transformers for Tabular Data

While GANs and VAEs are common, Diffusion Models and Transformer architectures are showing incredible promise for generating high-fidelity tabular and time-series data, often outperforming older techniques. This is the next frontier for data quality.

Score-based Generative Models · Attention Mechanisms in Tabular Data · Conditional Generation with Advanced Models · Scalable Training of Large Generative Models

  • This month: Read 2-3 seminal papers on Diffusion Models for tabular data (e.g., CTAB-GAN+, TabDDPM).
  • Next 3 months: Prototype a small tabular diffusion model using PyTorch and compare its performance against our current GANs.
  • Next 6 months: Present your findings and a recommendation for incorporating these models into our platform roadmap.
  • Ongoing: Keep an eye on new research and open-source implementations in this space.

Quick win: Start a personal project to implement a basic tabular diffusion model using a public dataset. It's a great way to learn without production pressure.

Federated Learning for Synthetic Data Generation

As data becomes more siloed and privacy-sensitive, the ability to train generative models on decentralised datasets without centralising raw data will become critical. This is a game-changer for collaboration across organisations or within highly regulated sectors.

Secure Multi-Party Computation (MPC) · Homomorphic Encryption · Federated Averaging Algorithms · Privacy-Preserving Data Sharing Architectures

  • This quarter: Research the basics of Federated Learning and its applications in data privacy.
  • Next 6 months: Explore open-source frameworks like PySyft or OpenFL for federated learning.
  • Next 12 months: Identify a potential internal or external use case where federated synthetic data generation could solve a data access problem.
  • Ongoing: Network with experts in the privacy-preserving AI community.

Quick win: Set up a simple federated learning example locally to understand the mechanics. It's a bit abstract until you see it in action.

11Staying current once you are in

What people here do to keep up
  • Regularly engage with academic papers and industry blogs on generative AI, differential privacy, and data engineering best practices. Stay curious!
  • Contribute to or actively follow relevant open-source projects in the synthetic data or privacy-preserving ML space.
  • Attend industry conferences (e.g., NeurIPS, KDD, Data + AI Summit, Privacy.Tech) to network and learn about emerging trends.
  • Participate in online courses or specialisations in advanced machine learning, deep learning, or data privacy (e.g., from Coursera, edX, or deeplearning.ai).
  • Mentor junior engineers, which is a fantastic way to solidify your own understanding and develop leadership skills.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, synthetic data engineering is complex, demanding, and often involves repetitive tasks. But what if you could offload a significant chunk of that to AI? At Zavmo, we're not just talking about AI; we're actively using it to make our engineers more productive, letting them focus on the truly hard, creative problems.

For a Lead Synthetic Data Engineer, AI isn't just a buzzword; it's a powerful co-pilot. You'll be using AI tools to automate tedious tasks, accelerate research, and even improve your communication. This means less time on boilerplate and more time on high-impact architectural design and strategic thinking.

Code Automation & Generation

Use AI coding assistants like GitHub Copilot or Tabnine to generate boilerplate code for generative models (e.g., GANs, VAEs), data validation scripts, and MLOps pipeline components. It'll suggest entire functions, saving you hours of repetitive typing and context switching. Frankly, it's like having another pair of hands.

Automated Quality & Privacy Reporting

Feed statistical outputs from your validation tools (like Great Expectations reports or differential privacy metrics) into an LLM agent. It can then synthesise the findings and generate a human-readable summary for non-technical stakeholders, highlighting key quality metrics, privacy guarantees, and potential risks. No more drafting lengthy reports from scratch.

Novel Architecture Research & Scaffolding

Use an LLM to quickly research, summarise, and compare the latest academic papers on emerging generative modelling techniques (e.g., 'Tabular Diffusion Models' or 'Conditional GANs'). The AI can then generate boilerplate Python/PyTorch code to serve as a starting point for implementing these new architectures. It's a huge head start on R&D.

Stakeholder Explanation & Documentation

Struggling to explain 'Fidelity vs. Privacy Trade-off' to the legal team? Use an LLM to generate clear, concise documentation and explanations of complex technical topics. For example, 'Explain Attribute Disclosure Risk to our Product team using a simple analogy' or 'Write the user guide for our internal synthetic data SDK'. It makes communication much quicker and clearer.
