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:

We are seeking a highly skilled Senior Full-Stack Developer with deep expertise in React and strong experience building backend services and deploying applications to Microsoft Azure. This role will focus on building, deploying, and optimising scalable, high-performance web applications that handle large volumes of data and integrate AI-driven components. You will work closely with backend engineers, cloud specialists, and AI teams to deliver intelligent, production-ready applications at scale. You will be expected to contribute to system design and architecture decisions, not just implementation.

Responsibilities

Design, build, and maintain scalable full-stack applications using React and modern JavaScript/TypeScript on the frontend, and Python on the backend.
Participate in system design from the outset, defining service boundaries, data flows, and architectural trade-offs rather than being handed a spec to implement.
Build front-end solutions that support high data throughput, performance optimisation, and responsiveness at scale.
Design and implement clean, well-documented APIs and backend services that integrate with the frontend and downstream systems.
Integrate front-end applications with AI-powered services, including LLM-based APIs and workflows and Agentic AI systems.
Work with automation and orchestration services, particularly within Azure.
Work with containerised environments such as Docker and contribute to cloud-native deployment pipelines.
Support CI/CD processes and promote reliable, repeatable deployments.
Collaborate on the deployment of applications to Azure, owning your deployments end to end.

Required Skills & Experience:

Extensive experience as a Senior Full-Stack Developer or similar role.
Expert knowledge of React, including modern patterns, hooks, state management, and performance optimisation.
Strong backend experience in Python, with a track record of building production-grade services. Candidates with a background in .NET or Java who are comfortable working in Python are equally welcome.
Proven system design ability. You can drive architecture discussions, justify technical decisions, and translate complex requirements into scalable solutions.
Proven experience deploying applications to Microsoft Azure.
Experience integrating applications with APIs, microservices, and distributed systems.
Familiarity with container technologies such as Docker and container-based deployment models.
Experience working on applications that handle large datasets or high-traffic environments.
Strong understanding of front-end performance, observability, and optimisation techniques.

Nice to Have

Hands-on experience integrating with LLM APIs such as OpenAI, Azure OpenAI, or similar.
Familiarity with agentic AI frameworks such as LangChain or LangGraph.
Experience building or consuming RAG pipelines, including vector search and document retrieval patterns.
Understanding of prompt engineering and how LLM-based systems behave in production.
Exposure to Azure AI services, including Azure Cognitive Search or Azure Machine Learning.
Experience working alongside data science or AI teams and translating their outputs into production-ready applications.

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]
