Senior Software Engineer

Senior Python Engineer | Ipswich (Hybrid) | £65,000 - £70,000 | Python

Location: Ipswich, hybrid working

Salary: £65,000 - £70,000 + benefits

Tech Stack:

• Backend: Python
• Architecture: Microservices, distributed systems
• Cloud: AWS, Azure, or GCP experience beneficial
• Tools: Git, CI/CD pipelines, REST APIs

Are you the kind of engineer who enjoys working on systems where correctness, reliability, and real world impact matter and you're looking for your next career challenge?

We’re working with a well-established but growing technology company building complex, data heavy software used in high stakes environments. This is not a greenfield startup chasing hype cycles, it is a product that is deeply embedded in critical workflows, where performance, accuracy, and robustness are non-negotiable.

You would be joining a team responsible for evolving a core platform, designing and building systems that handle large volumes of data, integrating external services, and ensuring everything holds up under real world pressure.

What you will be doing:

• Designing and building scalable backend systems in Python, with a strong focus on API design and data handling
• Owning features end to end, from discovery through to deployment and iteration
• Contributing to architectural decisions across a microservices based platform
• Integrating third party services and maintaining external libraries where needed
• Working closely with product and QA to deliver reliable, production ready software
• Mentoring other engineers and raising the overall technical bar within the team

What they are looking for:

• Strong Python experience, with a track record of building and maintaining production systems
• Solid understanding of system design, particularly around APIs and distributed architectures
• Experience working with AWS and modern deployment practices
• Engineers who care about code quality, CI/CD, and building systems that last
• Someone who can operate independently, but also contribute meaningfully to team direction and delivery
• Comfortable working in environments where the problems are complex and not neatly defined

Why this role stands out:

• You are working on a product that is already trusted and widely used, not something trying to find product market fit
• The engineering challenges are real, involving scale, data complexity, and system reliability rather than surface level features
• There is a balance of autonomy and responsibility, you are expected to think, not just execute
• A strong engineering culture that values good decisions over fast decisions

This is well suited to someone who enjoys getting into the detail of how systems behave in production, who takes pride in building things properly, and who wants to work on software that actually needs to work.
