Durlston Partners

Do you dream in pointers and measure time away from your keyboard in clock-cycles?

If so, I’m working with a development team for whom latency isn’t a metric, it’s treated as an existential crisis. They will need you (person who unironically loves 𝐜𝐨𝐧𝐬𝐭𝐞𝐱𝐩𝐫) to continue shaving off micros until they’re down into the nanos.

They treat undefined behaviour for C++2a and C++2b like a personal insult and will be very keen to hear if you have made 𝐬𝐭𝐝::𝐜𝐡𝐫𝐨𝐧𝐨 cry before. Other things that matter to them would be experience with lock-free programming and strong networking chops (gm Mr./Mrs. Kernel Bypass).

Bonus points if you’ve used 𝐩𝐞𝐫𝐟 to format your morning routine as well!

What this team offers in return:

• A comically powerful compute estate
• No legacy code (okay, maybe 1 or 2 𝐠𝐨𝐭𝐨 statements)
• A nerf gun arsenal for settling debates about RAII vs. GC
• Free therapy sessions (just kidding—valgrind –tool=callgrind is your therapy

We’re working with a crypto trading firm which prides itself on having some of the most high performance trading infrastructure in the industry. Sure, there are limits to how fast the orders can reach an exchange but this team has future-proofed its infra all the same. 

So what skills do these engineers have and what would they like you to share expertise in?

They’ve come from firms where the work they did was measured in nanos, not micros and typically have the following skills:

Optimising hardware for performance (CPU / GPU).

• Can you leverage SIMD and multiple cores?

Exceptional memory management skills.

• Would you know why reference-counted smart pointers (e.g., std::shared_ptr) still lead to memory leaks?

Networking skills which reduce OS kernel involvement for direct hardware access. 

• When comparing RDMA and DPDK; which one is your go-to for HFT?

The team has not lost any Engineers since they joined the team. What does this tell us? They are paid market-leading compensation and the work they do is intellectually stimulating enough, that they don’t need to go elsewhere for the most fun challenges in crypto trading.

Prior experience in HFT is heavily preferred but if you have a strong track record solving these problems outside of that niche, you may still have a shot!

Work authorisation in Singapore and the US will be required. Sponsorship is available for exceptional candidates to relocate to the UK.

Become employee #9 for a DeFi Exchange?

When it comes to teams in the crypto space, not all are made equal. Some don’t have the right backing, because the market doesn’t want what they’re building. Others have great backing but don’t have the right execution.

This team has the right backing AND the right execution. I’ve been recruiting for crypto firms for almost 8 years and have yet to see a team backed by so many of the biggest names in the industry, with real A-players responsible for building the product.

Sure, the headcount is currently small but the backing is mighty and there are unlikely to be many opportunities giving you the chance to have this amount of impact.

“Cool, so what will I be doing?”

You’ll be employee #9 of a firm building brand new services which will be powering onchain transactions. It’s likely to be a good fit for you if you love owning and shipping new features as quickly as possible, especially if you’d like to do so using modern web technologies. This may include:

• Creating a real-time UI for use by external trading counterparties, ensuring load times that are as fast as possible
• Implementing Web3 functionality; interacting with smart contracts, and handling transactions using libraries like web3.js or ethers.js

“How do I know if I’m a good fit?”

• You’ve built high-performance UIs for real-time systems before; it’s likely you’ll have done this in the quantitative trading space
• You’re comfortable working asynchronously with remote team members
• You pride yourself on having bullet-proof Computer Science fundamentals which may or may not have come from a top school
• You know modern JavaScript frameworks inside out and have a strong track record creating dynamic and scalable UIs
• You have a demonstrable interest in working in crypto to tackle novel engineering problems

Quantitative Developer – Crypto Hedge Fund – London

Looking for stability in crypto? We’ve got you.

If you’ve already dipped your toes into the exciting (and often chaotic) world of digital assets but are now craving something more solid and structured – this is where you want to be.

Why Now?

You’ve seen crypto evolve, and the industry is maturing fast, with institutional-grade infrastructure and serious players stepping up. But there’s still so much potential to tap into – the industry is in a similar position to traditional hedge funds in the late 90s / early 2000s, with inefficient and fragmented markets and strong retail participation.

Why Here?

This hedge fund combines the agility of a start-up with the stability of a well-established brand and reputation. You’ll build a greenfield crypto market-making platform from scratch in Java, and will write and improve the trading strategies, in an environment that prioritises innovation and impact.

You’ll join a close-knit team that values your input and your experience. Whether it’s improving automation, optimising execution, or introducing new tools and tech, your ideas will be heard. Plus, you’ll work side-by-side with Senior and Lead Developers who has 20 years of systematic trading and low latency expertise. It’s a place where you can grow, without the bureaucracy.

Why You?

• You’re already working in crypto and have hands-on experience building trading systems.
• You’ve have a knack low-latency tuning and optimisation.
• Your Computer Science fundamentals are rock-solid – you know your algorithms and data structures inside out.
• You’ve led projects or owned significant builds, and you’re ready for the next big challenge.

This role is designed for a crypto insider who’s ready to swap the volatility of start-ups for the stability and resources of a hedge fund. You’ll still be on the cutting edge, building and innovating.

• Transparency; two-way clarity on expectations and deliverables.
• Tax Free Income; the unrivalled feeling of opening your payslip and seeing a big fat zero next to Deductions.

There’s a lot I’ve intentionally left out, because your interview will assess you on more than how many years you’ve used Python, or if you have an AWS certification. That said, experience in a systematic trading environment will go a long way so best to assess this before hitting apply.
