Job description

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 Description

We're seeking a Senior Agentic Engineer to take end-to-end ownership of services for an internal AI assistant platform. You'll own vertical slices across the full stack—from the agents and MCP tool servers themselves, through the Terraform infrastructure that runs them on Azure, to the React workbench that puts them in front of staff. This is not a layered role; you'll take ownership of one or more complete services and contribute across the entire platform.

Key Responsibilities

• Architect and implement agentic systems using LangGraph, managing state graphs, checkpointing, and tool-calling patterns
• Design and deploy FastMCP servers that integrate with the platform
• Own infrastructure-as-code using Terraform to manage Azure resources (App Service, Cosmos DB, Key Vault, Managed Identity)
• Build and maintain the React workbench interface staff
• Ensure production-quality LLM applications with robust context management and agent observability
• Collaborate across the team to deliver features end-to-end—vertical slices, not layers
• Mentor junior engineers on agentic patterns and production best practices

Required Skills / Experience

• Production LLM applications (not prototypes)—deep understanding of tool-calling agents and context management
• Experience with TypeScript and React
• Azure platform fluency and Terraform infrastructure-as-code
• Demonstrated ability to take ownership of complete services
• Understanding of how to evaluate and monitor agent behavior in production
• LangGraph expertise (state graphs, checkpointing, persistence)
• Azure AI Search and retrieval evaluation
• Experience in regulated or critical-national-infrastructure settings
• Full-stack ownership mindset across frontend, backend, and infrastructure

Working at ClearRoute

We have grown from six founders to 180+ people across five countries in three years, and what sets us apart isn't the pace, it's how we grow.

• Real flexibility, in practice. We trust you to perform at your best and still have a life outside of work, with genuine hybrid working, a home office budget, an open feedback culture where your voice shapes decisions, and time off when life needs it (birthday included).
• When ClearRoute wins, you win. We offer profit share so success is shared, meaningful recognition for great work, and benefits that look after you and your family, including private healthcare, competitive salary benchmarking, and a confidential employee assistance program covering counselling, mental health support, and financial wellbeing.
• A community you'll genuinely want to be part of. Interest based communities like running and book clubs, Women in Tech group, monthly socials, and cross regional events bring people together across the company. An inclusive, collaborative culture where you don't need to conform to succeed, where people support one another and feel comfortable being themselves.
• Where meaningful work meets real growth. You will tackle complex, real world problems at the forefront of platform engineering, AI, security, and scalable systems. Your growth is supported by learning budgets, Udemy access, a clear career framework, internal mobility, and thought leadership opportunities that take your impact beyond ClearRoute.

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.
