Job description

Software Engineer | Trading Technology Start-up | Up to £120,000 + 15% Minimum Bonus | London, Tower Bridge (Hybrid)

A Software Engineer is needed for a fast-growing trading technology start-up that's building the platform brokers and traders rely on to manage client communication, market data, and real-time trading intelligence, all on one system. This is a high-impact hire, joining a small, sharp engineering team building new platforms from the ground up, with genuine input into technical direction from day one.

The business was founded to solve a very manual problem. Brokers and traders spend a lot of time managing client communication across various channels such as spreadsheets, calls, WhatsApp, and email. What started as a single database to centralise this has grown into a live platform that pulls in communications, market data, and stock notifications, giving traders real-time intelligence on when to act. The platform also plays an important role in compliance and market surveillance, capturing conversations and data across channels to protect against market manipulation and insider trading risk, and to preserve institutional knowledge if a trader or broker leaves.

Earlier this year, the business was acquired by a listed, global shipping, energy, and trading services group. This has given it backing, resources, and access to the bonus pools of a much larger organisation, while continuing to operate independently under its own brand and leadership.

As a Software Engineer, you'll work across the platform's backend and architecture, owning features end-to-end — from design and build through to testing and deployment. This is less about writing code to spec and more about genuinely understanding how the systems fit together; you'll work closely with senior engineering and the CEO, as well as directly with traders and clients to shape the product. This is a hands-on, SaaS engineering role in a business with a strong commodities and trading market focus.

Location: London, Tower Bridge (Hybrid — more office time during probation while you get up to speed, moving to greater flexibility afterwards)

Technology: Python, plus other backend languages such as Java, Rust, or Go

Key Responsibilities

• 5-6+ years' experience as a software/systems engineer
• A true software engineer rather than just a coder — someone who understands how computer systems and architecture work, not just how to write to a spec
• Strong experience in at least one other backend language (Java, Rust, Go, or similar), alongside solid Python fundamentals (doesn't need to be your current day-to-day language)
• Proven end-to-end experience: building, testing, and shipping features across the full software development lifecycle
• Experience in a SaaS / software-as-a-service environment
• Strong preference for candidates with a background in commodities, fintech, financial trading, or banking — smaller fintech experience is a plus
• Comfortable working directly with clients to inform product development, with strong communication skills
• Degree in computing or a related technical field desirable but not essential

Process: Multi-stage interview process including an initial general call, a technical conversation, an in-person technical/coding stage, and a final in-person culture-fit conversation.
