7Would you like it

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

What people enjoy
Technical Challenge & Impact

You'll be tackling some of the hardest computer science problems out there: low-latency systems, distributed computing, massive data processing. The direct impact of your work on our P&L will be visible, often in real-time. You're building systems that actually move markets, which is pretty exhilarating.

Spending a week deep-diving into a kernel-level network driver bug, finally finding the root cause, and seeing a direct 500ns latency improvement on a critical trading path.

Continuous Learning & Innovation

This isn't a job where you can rest on your laurels. You'll be constantly learning about new technologies, hardware, and trading strategies. We encourage experimentation and expect you to bring new ideas to the table, pushing the boundaries of what's possible in high-frequency trading.

Researching a new FPGA-based market data processing solution, building a proof-of-concept, and presenting it to leadership for potential integration into our next-gen platform.

Team Leadership & Development

You'll be guiding and mentoring a team of bright engineers, helping them grow their skills and tackle complex problems. Seeing your team members succeed and develop under your guidance will be a significant source of satisfaction. You're not just a coder; you're a force multiplier.

Helping a junior engineer debug a particularly tricky multi-threading issue, explaining the concepts, and then seeing them confidently solve similar problems independently a few weeks later.

What frustrates people
  • The 'simple' quant idea that requires a multi-week rewrite of a core component.
  • Spending days trying to debug a non-deterministic production bug that disappears when you attach a debugger.
  • The constant pressure to 'shave off nanoseconds' from latency, only to be limited by external factors like exchange network speed.
  • Dealing with messy, inconsistent historical market data from vendors that invalidates months of backtesting.
  • Explaining the value of a £250K hardware upgrade for a 500ns latency gain to someone who thinks 'latency' is just slow internet.
  • The never-ending battle between building new alpha-generating features and refactoring critical, but unglamorous, infrastructure.
What this role does not give you
  • A predictable 9-to-5 routine – market hours and production issues don't care about your schedule.
  • A purely academic or theoretical environment – this is about practical, real-world impact.
  • A role where you only write greenfield code – you'll be dealing with legacy systems and technical debt.
  • A place where you can avoid difficult conversations – you'll need to push back on unrealistic demands and explain complex technical trade-offs.

8Who you work with

This role directly impacts the firm's ability to execute profitable trading strategies. You're responsible for the technical integrity of systems that handle millions of transactions daily, meaning your work has a direct line to our P&L. You'll also be instrumental in building out new capabilities that allow us to enter new markets or trade new asset classes, which is pretty fundamental to growth.

Inside the business
  • Quantitative Researchers (Quants)
  • Trading Desk Heads
  • Head of Infrastructure
  • Product Managers for Trading Systems
  • Risk Management Team
Outside the business
  • Exchange Technical Contacts
  • Market Data Vendors
  • Network Hardware Providers
  • Cloud Service Providers (e.g., AWS technical account managers)

9What you need before you start

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

  • At least 5 years of hands-on experience as a Senior Algorithmic Trading Engineer or similar role, with a strong track record of designing and delivering complex, low-latency systems.
  • Demonstrable expertise in C++ (modern standards) and Python, particularly in a high-performance, multi-threaded context.
  • Deep understanding of market microstructure, order book dynamics, and common trading strategies.
  • Proven experience leading technical projects and providing mentorship to junior engineers.
  • A solid grasp of operating system internals (Linux kernel tuning) and network protocols (TCP/UDP, multicast) relevant to low-latency trading.
  • Experience with distributed systems and high-throughput data processing (e.g., Kdb+, Kafka).

10What to practise next

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

Advanced Distributed Systems for Resilience

As our systems grow in complexity and scale, ensuring continuous availability and fast recovery becomes paramount. You'll need to master advanced patterns for fault tolerance, state replication, and graceful degradation, building systems that can withstand partial failures without impacting trading.

Event Sourcing & CQRS · Chaos Engineering · Consensus Algorithms (e.g., Raft, Paxos) · Multi-Region Deployment & Disaster Recovery

  • This month: Read 'Designing Data-Intensive Applications' by Martin Kleppmann—it's a bible for this stuff.
  • Next quarter: Lead a post-mortem for a recent production incident, focusing on systemic resilience improvements.
  • Month 4-6: Design a new component with an explicit focus on multi-region deployment and automated failover.
  • Month 7-9: Propose and implement a small-scale chaos engineering experiment on a non-critical system to test its resilience.

Quick win: Start thinking about every new feature in terms of its failure modes. What happens if this service goes down? How quickly can it recover? How does it impact upstream/downstream?

11Staying current once you are in

What people here do to keep up
  • Regularly attend industry conferences (e.g., CppCon, HFT conferences, AWS re:Invent) to stay abreast of the latest technical advancements and networking opportunities.
  • Contribute to open-source projects, particularly in areas related to low-latency computing, distributed systems, or financial technology. This shows initiative and practical application.
  • Pursue advanced online courses or certifications in areas like hardware acceleration (FPGAs/GPUs), advanced distributed systems design, or machine learning for time-series data.
  • Actively participate in internal technical guilds or communities of practice, sharing your expertise and learning from peers.
  • Mentor junior engineers, formally or informally, to hone your leadership and communication skills.

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 & LLM Integration

Competitors are already using sophisticated LLMs to accelerate research, analyse market news, and even assist with code generation. Engineers who can effectively 'talk' to these models will dramatically outproduce their peers. This isn't just about asking simple questions; it's about crafting complex, chained prompts for analytical tasks.

  • Context Windows & Token Limits
  • RAG (Retrieval-Augmented Generation)
  • Agentic Workflows
  • Output Validation & Hallucination Detection

Hardware Acceleration (FPGAs, GPUs) for Trading

The 'free lunch' of CPU clock speed increases is long gone. To achieve the next level of latency reduction and throughput, we'll need to offload more processing to specialised hardware. Understanding how to design systems that effectively use FPGAs or GPUs for specific trading tasks (e.g., market data parsing, signal generation) will be crucial.

  • FPGA Design Principles (VHDL/Verilog)
  • CUDA/OpenCL Programming
  • Hardware-Software Co-design
  • Latency Measurement & Optimisation on Hardware

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, you're already juggling complex code, demanding quants, and the relentless pursuit of nanoseconds. What if you could offload some of the more tedious, time-consuming tasks to AI, freeing you up for the truly challenging architectural work and strategic thinking?

We're not talking about replacing your brain; we're talking about giving you a seriously powerful co-pilot. AI tools are rapidly evolving, and we're integrating them to help our Algorithmic Trading Engineers focus on what they do best: building lightning-fast, rock-solid trading systems. Here's how AI can help you reclaim your week:

Smart Code Generation & Refactoring

Use AI assistants like GitHub Copilot to quickly generate boilerplate C++ for market data parsers or Python for backtest analysis scripts. Feed legacy C++ code to an LLM to suggest modern refactoring patterns, identify hidden performance bottlenecks, or even translate complex comments into clearer explanations. It's like having another senior engineer constantly reviewing your code for efficiency.

Proactive Anomaly Detection in Logs

Forget manually sifting through terabytes of logs during a production outage. AI tools can now analyse real-time log streams, automatically flagging anomalous behaviour – think sudden latency spikes, unusual message patterns, or unexpected order rejections. It can even suggest a probable root cause, giving you a massive head start when every second counts. This means less frantic searching and more targeted fixing.

Exchange Spec Summarisation & Task Generation

When an exchange drops a new 300-page PDF detailing API changes, you used to spend days poring over it. Now, feed it to an LLM to extract a concise summary of breaking changes, identify all impacted FIX message types, and even generate a preliminary checklist of required development tasks for your team. This saves you hours of tedious reading and helps you plan your migration much faster.

Automated Backtest Sanity Checks & Reporting

After a backtest run, have an AI agent analyse the results for common pitfalls. It can automatically flag signs of overfitting, look for unrealistic fill rates, or spot data inconsistencies. It can even draft a preliminary summary of the strategy's performance and potential weaknesses, giving your Quants a head start on their analysis and you more time to focus on the execution engine itself.
