Must-have: hands-on engineering depth and platform-wide architecture leadership, not one or the other.

The platform here has grown fast, and integration across services has got messy with it: systems that work but don’t talk to each other cleanly, with little in the way of defined contracts or shared standards. This client is hiring their first ever Principal Architect to sort that out properly, reporting straight into the CTO. They’re a purpose-led organisation sitting at the intersection of data, climate and global finance, running one of the world’s most widely used environmental disclosure systems, relied on by tens of thousands of companies and institutions to report impact and shape investment decisions. It’s a global team, and the London office is a key engineering hub: a tight-knit group of tech leads and platform specialists working closely together.

You’ll split your time between architecture and code, working directly with those tech leads across squads. The job is to make the current state legible, define where it needs to go, and help teams get there without slowing delivery down. There’s real ownership here, both technically and in how engineering standards evolve across the business.

What They’re Looking For:

  • Platform-wide architecture leadership (initiatives spanning multiple teams and products, not single systems)
  • Current and target-state architecture (documenting a complex estate and defining where it goes)
  • Integration standards and governance (service boundaries, contracts, shared engineering principles)
  • Technical debt reduction and multi-year roadmaps (aligning several engineering teams behind one direction)
  • Hands-on engineering (still in the code, reverse-engineering live integrations and historical design)
  • TypeScript and Node.js
  • System design (distributed, end-to-end platforms)
  • Azure or AWS

What You’ll Work With:

  • React and Next.js
  • Nest.js
  • Python API integrations (internal and third-party)
  • Cursor / CoPilot (AI-assisted development)
  • Distributed service architecture

Nice to Haves:

  • Experience standing up a Principal Engineer or Platform Architect function from scratch
  • Track record taking a fast-grown platform and bringing its integration under control
  • Mentoring or growing a senior engineering group

Why Join?

The pull here isn’t the tech, it’s the mandate. You’ll be the first person ever to hold this seat. You’ll start by mapping what exists and where it breaks down, then introduce an integration model that squads will actually adopt, not a theoretical architecture exercise. From there it’s building reference implementations, shaping how APIs get designed, and lifting the developer experience across the whole platform. Because it’s the first role of its kind in the business, the expectation is it grows into a small group of senior engineers over time, so you’d have a genuine say in how that function takes shape.

Employee Benefits:

  • Generous non-contributory pension
  • Life assurance
  • Employee Assistance Programme
  • Training and development support
  • Flexible working arrangements
  • Bank holidays on top of standard annual leave

If you’ve watched integration get messy across a platform and wished for the space and the mandate to fix it properly, this is worth a conversation. Apply and I’ll give you a call.

How to prepare for a job interview at Prism Digital

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 Prism Digital uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Showcase Your Projects

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. 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.
