About the Company

They're scaling quickly, shipping daily, and looking for technical leads / principal engineers and/or technically minded software development managers who can help found a Scottish chapter of their UK engineering team.

The Opportunity

This is a technical leadership role for someone who wants to shape a product from first design conversation through to code running in production while staying close to the build the whole way. You'll move fluidly between hands-on delivery and architectural decision-making, working across a modern stack and deploying multiple times a day. You will be challenged to experiment and champion AI, where currently almost 80% of code is agent generated . If you want influence over how things are built, not just what gets built, this is worth a conversation.

• Experimenting responsibly with AI, choosing your tooling and how it is utilised.
• Work with initiative managers to break ambitious ideas into deliverable epics and stories.
• Turn user stories into production code as a high-performing individual contributor and as lead developer and embedded architect.
• Champion the quality, maintainability and operability of everything you and the team ship (fellow engineers and agentic agents).
• Stay close to the product in production, supporting it and resolving issues as they arise.
• Shape ongoing design, architecture and implementation decisions as the platform evolves.

What We're Looking For

• 10+ years' full stack software development experience, with genuine technical leadership under your belt.
• 5+ years' fluency in JavaScript and TypeScript full stack, this is non-negotiable.
• Strong grasp of system design and domain modelling, with a commercial mindset behind every technical decision.
• A track record of clean code, SOLID principles and thoughtful design patterns.
• Broad full stack experience, ideally gained building large-scale SaaS platforms.
• Comfortable operating in a mature CI/CD environment, deploying continuously with a DevSecOps approach.

• An aptitude for problem-solving, with the appetite to pick up new tools and techniques fast.
• Excellent interpersonal & collaboration skills, with confidence working directly with customers.
• An understanding of building systems that hold up and perform at scale.
• A genuine enthusiasm for building secure systems and championing security best practice.

Useful:

• Exposure to NodeJS microservices, Vue, Redis, SQL Server or Snowflake.
• Experience deploying and operating services in AWS.
• A track record of driving high standards and pushing a team towards ever-higher levels of efficiency.

Why This Role?

• Real influence as you will be shaping products from the first design conversation, not just executing someone else's spec.
• A modern, fast-moving stack with daily production deployments and a DevSecOps culture that actually works.
• A company culture built around a "One Team" and growth mindset, not just words on a wall.
• Volunteer days, fundraisers and charity initiatives — a business that gives back.
