Job summary

ClearRoute is seeking a backend engineer to design and build the scalable Python microservices and API layer powering an AI-driven code modernisation platform. You will help orchestrate agentic workflows, integrate external capabilities, and ensure production-grade reliability at scale.

You should have hands-on Python, microservices, distributed systems experience, and real curiosity in GenAI, LLMs, and agent frameworks.

Qualifications

• Strong Python engineering and production-grade code with real-world load handling.
• Experience designing and building microservices and RESTful APIs in production.
• Solid software design principles and distributed/asynchronous system knowledge.
• Genuine interest in GenAI and agentic systems with practical delivery experience.
• Practical experience with LLMs, agent frameworks, or prompt engineering in real projects.
• Direct experience with MCP or similar agent tool-serving patterns.
• Git workflow automation and GitHub/GitLab API integration for developer tooling.

Responsibilities

• Design, build, and maintain scalable Python microservices and APIs powering agentic workflows in production.
• Build and integrate MCP servers and tools, enabling agents to reliably discover, call, and chain external capabilities.
• Own backend services lifecycle for AI agents, ensuring robustness, observability, testing and production readiness.
• Shape agentic architecture decisions, including tool-calling patterns and multi-agent orchestration.

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:

Design and build the scalable service and API layer that powers an AI driven code modernisation and migration platform, combining agentic workflows with deep static analysis to automate the understanding, transformation, and migration of legacy systems at scale.

Key Responsibilities:

• Design, build, and maintain scalable Python microservices and APIs that power and orchestrate agentic workflows in production

• Build and integrate MCP servers and tools, enabling agents to reliably discover, call, and chain external capabilities

• Own the full lifecycle of backend services supporting AI agents, ensuring they're robust, observable, well-tested, and production-ready at scale

• Actively shape agentic architecture decisions, from tool-calling patterns and orchestration strategies to state management and multi-agent coordination

Required Skills & Experience:

• Strong Python engineering skills: writing clean, testable, production-grade code that holds up under real world load

• Proven experience designing and building microservices and RESTful APIs in production environments

• Solid grounding in software design principles and systems thinking, especially around distributed, event-driven, or asynchronous systems

• Genuine, hands-on interest in GenAI and agentic systems not just familiarity with the concepts, but active experimentation or delivery experience

• Practical experience with LLMs, agentic frameworks ("e.g. LangGraph, CrewAI, or similar"), or prompt engineering in real projects

• Direct experience with MCP, or comparable agent tool-serving and tool-calling patterns

• Working knowledge of Git workflow automation, and experience with GitHub/GitLab APIs for building developer tooling or automation

Desirable Experience:

• Deep understanding of how agents consume, select, and reason about external tools and services

• Some exposure to frontend development or UI frameworks (React, Vue, or similar) for building agent-facing interfaces or observability dashboards

• Comfortable operating in a container-native environment (Kubernetes, Docker), including deploying and scaling agentic services

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).

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.
