Senior Software Engineer

Senior Software Engineer (Sports betting)

Up to £120,000 + Bonus + Excellent Benefits

London | Python | Java | GCP | Real-Time Distributed Systems

Build systems where performance really matters.

If you're a Senior Software Engineer who gets excited by high-performance systems, distributed architecture and real-time data, this could be a seriously interesting opportunity.

We're partnering with an innovative technology business investing heavily in its engineering function and building highly available, cloud-native platforms that operate at significant scale.

This isn't a role where you'll simply be maintaining an existing code-base.

You'll be solving complex engineering problems, shaping architecture and working on systems where performance, scalability and reliability genuinely matter.

You'll have significant technical ownership, influence over engineering decisions and the opportunity to work alongside a highly capable team tackling some genuinely challenging back-end problems.

The Role

You'll be a key part of the engineering team, building and evolving back-end platforms that process large volumes of real-time data and integrate with external systems.

Please note we are only considering candidates who have previous betting/gaming/casino/gambling (or similar) industry experience at this time.

You'll be involved in

Designing and building highly scalable backend services

Python and/or Java as one of your core programming languages

Developing cloud-native, event-driven applications

Building integrations with third-party platforms and APIs

Designing and optimising real-time data processing pipelines

Working with distributed systems where availability and performance are critical

Identifying and solving complex performance and scalability challenges

Contributing to architectural and technical decisions

Improving resilience, observability and overall system reliability

Working closely with engineers and technical stakeholders to deliver high-quality software

Supporting infrastructure, deployment and continuous improvement

The Technology

You'll be working across a modern, cloud-native engineering environment including:

Python | Java | GCP | Docker | REST APIs | Event-Driven Architecture | Streaming | Distributed Systems | Real-Time Data Processing

The team is focused on building robust, scalable systems rather than simply following a prescribed technical playbook so your engineering judgement will genuinely matter.

What We're Looking For

We're looking for a Senior Engineer who enjoys getting into the difficult technical problems.

Please note we are only considering candidates who have come from the betting/gaming/casino/gambling (or similar) industries at this time.

You'll ideally have

Strong commercial Python experience

Professional Java experience

Experience building backend or distributed systems

Cloud experience: GCP preferred, although AWS or Azure is also valuable

Experience with Docker and containerised applications

Strong REST API development experience

Experience with event-driven architectures or messaging

Experience working with real-time data or high-throughput systems

An understanding of designing scalable data processing pipelines

A strong interest in performance, reliability and system architecture

Your background could come from a range of high-performance environments, including:

Sports betting, iGaming or wagering technology

Trading or market-data platforms

Low-latency or high-throughput applications

Streaming and event-driven architectures

FIX Protocol or electronic trading integrations

Financial services or electronic trading

You don't necessarily need experience in every area, what's important is that you've worked on technically demanding systems where speed, scale and reliability are critical.

What's In It For You?

Up to £120,000 depending on experience

Annual performance bonus

Private healthcare & dental

Pension

25 days' holiday + bank holidays

Wellness and gym membership

Complimentary breakfasts

Regular team lunches

Excellent office facilities

A genuinely collaborative, engineering-led environment

Significant technical ownership and influence

Why this role?

If you're looking for your next Senior Engineering role and want to move beyond simply delivering tickets, this is an opportunity to work on complex systems, influence architecture and solve problems that actually require serious engineering thinking.

You'll be working with modern technology, talented engineers and a business that is continuing to invest in its technology platform.

If Python, distributed systems, real-time data and high-performance engineering sound like your kind of challenge, get in touch for a confidential conversation.
