Remote Senior Software Engineer – Retail Platform + AI

OneView Commerce; Greater London; Hybrid; GBP 70,000 - 110,000; Full time

Job summary

OneView Commerce is seeking a Senior Software Engineer to help shape a distributed platform used by thousands of shops worldwide. You will design and implement complex features, drive architectural decisions, and mentor junior engineers in a remote-first, fast-moving team environment.

You will work with modern languages, cloud platforms, and AI-enhanced workflows to deliver reliable, scalable store experiences across international retail estates.

Qualifications

• 5+ years building production software, with a track record of delivering complex work independently.
• Strong in a modern typed language such as TypeScript, Go, Java, Kotlin, Python, or C#.
• Depth on either the client side, in a component framework such as React, Angular, or Vue, or on the service side.
• Builds and consumes REST and event-driven interfaces, and knows when each is the right choice.
• Public cloud experience with AWS, Azure, or Google Cloud, including managed and serverless compute patterns.
• Data modelling across relational and document stores, and can explain why a query is slow.
• Test-first practice. Writes tests as part of finishing work rather than as a later phase.
• Ships through the team's CI/CD pipeline rather than around it, and can read a failing build.
• Debugs a production problem from logs, traces, and metrics rather than by guessing.
• Reviews code well. Raises the standard without becoming the reason the team is waiting.
• Works from little direction. Takes an ambiguous requirement, asks questions that resolve it, and produces something defensible.
• Has mentored at least one engineer, and can say what changed for them.
• AI-assisted development as normal practice, and can explain every line of generated code they ship.

Responsibilities

• Design and build complex features and integration services end to end, from little direction, for a platform running continuously across thousands of shops in multiple countries.
• Take the hardest item on the team's backlog and be trusted with it.
• Own the technical design for significant pieces of work. Write it down, take it to the team and the Lead Software Engineer, and change it on the strength of the argument rather than defending it.
• Lead reviews of colleagues' work, and make review the place code gets better.
• Contribute to the team's choices about methods, libraries, and tooling, argue for them on evidence, and bring the Lead Software Engineer the problems worth solving.
• Work with the Product Owner to shape what gets built: challenge scope that is not worth its cost, surface technical constraints, and offer cheaper options when possible.
• Write tests that prove your work now and catch regressions later.
• Run technical investigations, prototype when needed, and come back with a team-ready recommendation.
• Break large work into incremental chunks so value reaches shops quicker.
• Estimate and sequence work honestly, raising risk to sprint commitments when needed.
• Own your work in production: instrument, monitor, and fix issues as they occur.
• Mentor a Software Engineer to help them improve, not just complete tasks.
• Participate in incident response, on-call, and post-incident reviews for systems you own.
• Document what you build well enough for safe future changes.
