  • Delivering a production Internal MCP Gateway providing discovery, security, policy enforcement, observability, and lifecycle management for MCP tools and Skills.
  • Designing and building MCP servers and Skills that expose internal and vendor systems safely to agents.
  • Establishing evaluation, quality control, and governance mechanisms so MCP tools and Skills can be promoted through PTB/PTO and operated with confidence at scale.
  • The programme follows a ‘build for’ model today, with a strong emphasis on defining the future product and platform experience, patterns, and contribution pathways that will enable federated scale over time.
  • Own and maintain SDD/ADD design documentation as governed, up‐to‐date artefacts.
  • Drive designs through architecture governance, securing Dev/Test and Production approvals.

  • Strong understanding of architecture governance processes and stakeholder engagement.
  • Ability to translate complex AI/ML designs into clear documentation.

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If London Stock Exchange uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
