Lead Platform Engineer

Lead Platform Engineer Up to £90,000 Belfast Hybrid
We are working with a globally recognised financial services organisation to hire two Lead Platform Consultants into their growing product security function. This is a senior individual contributor role for someone who can operate as a high-impact technical advisor and still be close to the code every day.
This is not a strategy-only role. You will shape platform strategy, lead architecture reviews, and embed secure-by-design principles across engineering teams, while remaining genuinely hands-on. You will engage directly with senior leadership, translating complex technical decisions into clear business outcomes, and mentor engineers across the organisation in modern engineering practices.
The function is growing fast, with a strong focus on AI security, API security, and SaaS security. If you want to influence how a major organisation builds security in from the ground up rather than bolting it on, this is a strong opportunity to do that.

What you will be doing:

• Acting as a trusted technical advisor across multiple engineering teams


• Leading architecture reviews, discovery sessions, and strategic planning


• Embedding threat modelling and secure-by-design principles into the development lifecycle


• Communicating platform strategy and security posture to senior leadership


• Mentoring engineers in systems thinking, reusable design, and modern delivery practices


• Driving adoption of emerging technologies including AI tooling

What we are looking for:

• 5+ years hands-on software engineering, Java and JavaScript are essential


• Experience across multiple programming paradigms including object-oriented, procedural and functional languages


• 3+ years architecting distributed systems, microservices, Kubernetes and Docker on AWS or Azure


• Proven track record as a high-impact technical advisor across multiple engineering teams


• Expert knowledge of Agile/XP, TDD, paired programming and CI/CD

A strong differentiator but not essential:
Security exposure in any of the following areas will set you apart: threat modelling, Zero Trust architecture, IAM, OWASP, secure-by-design, or API security.

The details:

• Salary: £90,000


• Location: Belfast


• Working pattern: Hybrid, no set minimum in-office days but a preference for regular in-person collaboration


• Two positions available


• No people management responsibility
