Senior Forward Deployed Platform Engineer (m/w/d)

Senior C++ Software Engineer Remote (UK-based) | Full-Time About Us Reactive Markets is the 2026 OTC Trading Platform of the Year ( Risk.net ). Our network handles over $75 billion in daily trading volumes across FX, Equities, and Cryptocurrency, connecting 60+ of the world's leading liquidity providers. We build trading systems that operate at the edge of what's technically possible — where nanoseconds matter and a dropped message costs real money. Our engineering team is small, senior, and deeply invested in the craft of building cutting edge, reliable, high-performance systems. The Role We're looking for a Senior C++ Software Engineer who can shape the technical direction of our Switchboard trading platform while continuing to write excellent code. You'll work on the most performance-critical components — pricing engines, connectivity gateways, market-data systems, and the messaging layer that ties them together — and you'll have a direct influence on architectural decisions that affect the entire platform. This is not a role where you write code and throw it over a wall. You build it, you test it, you deploy it, you support it in production, and you improve it. Our engineers own the full lifecycle — from design through to operational excellence. When something breaks at 4pm on a Friday, you're part of the team that investigates and fixes it. Beyond your own delivery, you'll provide technical oversight across the team — reviewing designs, challenging assumptions, and mentoring engineers who are earlier in their careers. You'll help us maintain the quality bar that our clients depend on, and you'll contribute to the architectural decisions that determine how well our platform scales. Occasional hours outside the normal working day are required for production releases, scheduled maintenance windows, and Level 3 support during critical incidents. We keep this to a minimum and recognise the commitment — but owning a production trading platform means being there when…

Our engineering team is small, senior, and deeply invested in the craft of building cutting edge, reliable, high-performance systems. The Role We're looking for a senior full-stack engineer to build the trading platform our clients use every day. Despite the "frontend" name, this is not a UI-only role — our Frontend team works across the whole application stack in TypeScript and Rust, from the trader-facing interfaces down to the services behind them. It's distinct from our Backend team, who own the low-latency C++/Go trading engine. This is a senior individual contributor role for someone who takes on the hardest problems and delivers them under their own steam. You'll own complex, ambiguous, performance-critical work end-to-end — designed, built, tested, deployed, and supported in production. You lead through code, craft, and mentoring, setting the technical example the rest of the team calibrates to. This is not a role where you write code and throw it over a wall: our engineers own the full lifecycle, and when something breaks, you're part of the team that investigates and fixes it. Occasional hours outside the normal working day are required for production releases, scheduled maintenance windows, and Level 3 support during critical incidents. We keep this to a minimum and recognise the commitment — but owning a production trading platform means being there when it matters. What You'll Work On Complex full-stack features in TypeScript and Rust — from trader-facing interfaces to the application services behind them Real-…

Technical Delivery Analyst Remote (UK-based) About Us Reactive Markets is the 2026 OTC Trading Platform of the Year ( Risk.net ). Our network handles over $75 billion in daily trading volumes across FX, Equities, and Cryptocurrency, connecting 60+ of the world's leading liquidity providers. We build trading systems that operate at the edge of what's technically possible — where nanoseconds matter and a dropped message costs real money. Our engineering team is small, senior, and deeply invested in the craft of building cutting edge, reliable, high-performance systems. The Role We're hiring the first dedicated Technical Delivery Analyst. You will own the delivery of software projects end-to-end — from requirements through to production — working alongside engineers to ensure work lands on time, risks are visible, and stakeholders always know where things stand. As our engineering organisation grows into more specialised teams, you are the person who sits across the space between them — owning the dependencies, coordination, and communication that no single team owns. This is not an administrative role. You need to understand the technology being built, speak credibly with engineers about architecture and trade-offs, and translate technical reality into clear communication for the business. You are the person who knows what is happening, why it matters, and what might go wrong — and you make sure everyone else knows too. You will work closely with the Head of Technical Delivery and daily with Engineering, TechOps, and Product, with regular interaction with client-facing teams (Sales, Client Services). The role offers a clear path to Delivery Manager as the team grows and you take on broader ownership. What You'll Work On Delivery Ownership: Own projects from inception to production — responsible for outcomes, not just process Understand technical scope, architecture, and dependencies well enough to anticipate problems before they surface Ensure infrastructure, testing…
