Full job description

About Us:

ClearRoute is an engineering consultancy bridging Quality Engineering, Cloud Platforms and Developer Experience. We help enterprises reliably bring high-impact digital products to market faster, cheaper, and safer, working with technology leaders facing complex business challenges.

We take as much pride in our people, culture and work-life balance as we do in making better software. We’re not just making better software. We’re making the making of software better. Collaborative, entrepreneurial and dedicated to problem solving, we bring the step change our customer need to sustain innovation. Our values challenge us to do the best we can for ClearRoute, our customers and most importantly our team. This is an opportunity for you to build the organisation from the ground up, use your voice to drive change and help transform organisations and problem domains.

Role:

Full-stack developers with a strong front-end focus, responsible for building the Superhighway control plane and the golden-path tooling engineers use to ship.
This is an AI-enabled role: you'll work agentic-first, using an agentic harness (Claude or similar) to drive implementation, not as an occasional assist.
You're as comfortable orchestrating agents to generate, validate, and test code as you are writing it yourself.
The role pairs modern front-end development (React) with working knowledge of Python services and APIs.

Key Responsibilities:

Develop and maintain front-end components using React for the control plane and audit/compliance/cost views
Build responsive, scalable, high-quality UI features for self-service data exploration and platform interaction
Drive implementation through an agentic harness: prompt, steer, and validate agent-generated code rather than hand-cranking it
Contribute to backend development (Python/FastAPI) where required
Build templated archetypes and golden-path kits that accelerate onboarding and development for other teams
Collaborate with UX/UI to ensure accurate implementation of designs
Ensure performance, security, and maintainability, with a testing-first mindset

Required Experience:

Strong experience with React and modern JavaScript/TypeScript
6+ months hands-on with agentic editors (Claude, etc.) and a clear understanding of agent risks and mitigation
Experience building web applications with API integrations
Working knowledge of Python (FastAPI a plus) for backend/API development
Familiarity with REST APIs and microservices architecture
Strong focus on acceptance testing and architecture testing (unit tests enforcing standards: line limits, design patterns, imports)
Experience with version control and CI/CD practices
Proactive communicator who unblocks themselves and collaborates across a matrix organisation (no quiet handle-crankers)

Desirable Experience:

Experience integrating AI/ML services (LLM APIs, embeddings, agent frameworks)
AWS native development and deployment experience
Policy-as-code expertise
Snowflake or data-product experience (producing and consuming)
Data visualisation libraries (charts, dashboards)
Authentication and RBAC implementation
Experience building developer platforms, golden paths, or internal tooling

At ClearRoute, we believe diverse perspectives lead to better outcomes, and inclusion creates the conditions for everyone to thrive. We are proud to have built a family friendly working environment and have many employees who have caring responsibilities alongside work. We welcome applications from people who require flexibility and will be happy to discuss needs on an individual basis.

We are committed to fostering a culture where all team members feel respected, supported, and empowered to do their best work. We celebrate individuality and our differences and understand that some differences may mean that you require changes made to the interview process. We are happy to cater to your needs to make the interview accessible, if this is something you require please let us know by emailing us at [email protected]
