Job description

Senior Full Stack Software Engineer

Location: UK Remote

Engagement: Permanent

Interview Process: Single stage technical interview

The Opportunity

At OCHO, we build teams for organisations where engineering quality is taken seriously.

This role sits within a high performing product group building large scale operational software used daily by thousands of field based users. The engineering challenges here are real. Scale, reliability, data flow, and user experience all matter. The team moves quickly, values autonomy, and relies on senior engineers who can bring technical maturity from early product thinking through to delivery.

We are looking for a Senior Full Stack Engineer who can own solutions end to end. Someone who thinks beyond individual tickets and understands how backend services, frontend experiences, and product decisions come together to create scalable software.

This is not a surface level full stack role. To succeed here, you will have delivered meaningful functionality across both backend and frontend, owned architectural decisions, and worked closely with Product to shape the right technical approach.

What You Will Be Doing

• Partner with product teams from ideation through to delivery, shaping solution design and technical direction.
• Design and build substantial backend features that underpin complex, large scale field operations.
• Deliver high quality React based user experiences that are performant, intuitive, and reliable.
• Lead discussions around system design, data flow, and architectural trade offs.
• Write clean, maintainable code supported by meaningful automated tests.
• Drive continuous improvement across code quality, patterns, and engineering practices.
• Mentor other engineers and help raise technical standards across the team.

What You Will Bring

• A proven track record delivering complex features across both backend and frontend.
• Strong professional experience with React including component architecture and state management.
• Solid backend engineering experience using a modern language and framework.
• Experience shaping system design and architectural decisions, not just implementing requirements.
• Comfort working in distributed, service oriented, or event driven systems.
• Strong understanding of data modelling, API design, and performance considerations.
• A mindset oriented towards ownership, product thinking, and improving engineering culture.

Why This Role

You will work in an environment that values initiative, technical leadership, and thoughtful engineering. Your input will matter. Your decisions will have visible impact. And full stack genuinely means full stack.

The interview process is intentionally simple. A single technical interview focused on system design, code reasoning, and problem solving. Clear, fair, and efficient.
