Are you an experienced Platform Engineer with a passion for backend development and cutting edge AI? Do you hold active SC clearance and want to work on systems that push the boundaries of intelligent automation?
We’re looking for a highly skilled Platform Engineer to join our team and lead the backend development of a powerful, self-service agent platform. This platform allows engineers and business users to design, configure, and deploy AI agents using Model Context Protocol (MCP) and AWS Bedrock. If you thrive in a fast-paced, innovation-driven environment, this role is for you.

• Develop scalable, secure RESTful APIs and GraphQL endpoints
• Integrate AWS foundation models and optimise their performance across use cases
• Create abstraction layers so non-technical users can deploy AI agents easily
• Implement strong logging, monitoring, and observability
• Work closely with frontend developers to ensure seamless integration
• Set up and manage CI/CD pipelines using GitLab
• Contribute to containerisation and deployments on OpenShift

What You’ll Bring:

• 3+ years backend development experience with Node.js/Next.js
• Proven experience with AWS services (particularly Bedrock & AI/ML integrations)
• Strong understanding of REST APIs, microservices, and secure coding
• Experience with CI/CD pipelines (GitLab preferred)
• Solid background in SQL and NoSQL databases
• Ability to work independently and drive architecture decisions
• A relevant degree or equivalent experience

Desirable: 

• Experience with Kubernetes and OpenShift
• Familiarity with MCP or agent-based frameworks
• Knowledge of LangChain, LlamaIndex, or other orchestration tools
• Background in building developer tools or platforms
• Understanding of LLM prompt engineering and optimization

Join us to work on a high-impact platform where innovation meets scale, and AI becomes accessible to everyone — all while supporting secure, mission-critical systems.

Active SC clearance is mandatory — applicants without current SC clearance cannot be considered.
