Job description

Neulinx have partnered with a fast-growing B2B SaaS product company to hire an experienced Senior Full-Stack Engineer to join their engineering team at an important stage of growth.

This is a hands-on senior role suited to someone who enjoys building high-quality product features, taking ownership of complex systems, and influencing technical direction through strong engineering practice rather than people management.

You’ll work closely with the CTO and Principal Engineer in a small, highly capable team, helping to design, build and scale a modern, multi-tenant SaaS platform used by enterprise customers.

What you’ll be doing

• Designing and delivering complex features across the full stack, with a focus on scalability, security and maintainability
• Taking end-to-end ownership of areas of the platform, from design through to production
• Contributing to architectural decisions around event-driven systems and SaaS scaling patterns
• Writing high-quality code and providing thoughtful, senior-level code reviews
• Working closely with engineering leadership to refine requirements and make pragmatic technical decisions
• Leveraging AI-assisted development tools as part of your day-to-day workflow

What they’re looking for

• 8+ years’ experience building production-grade SaaS products
• Strong hands-on experience with Node.js and TypeScript
• Solid full-stack background, with professional experience using React or Angular
• Experience working with relational and NoSQL databases such as PostgreSQL, Redis or MongoDB
• A product mindset, strong ownership, and the confidence to influence technical direction

Nice to have

• Exposure to AI or LLM-based systems
• Experience with data or analytics pipelines

Why consider it

• Fully remote role with a high level of autonomy and trust
• Senior-level influence without people management responsibility
• Modern tech stack and an engineering-led culture
• Private healthcare included
• Scope to grow technical ownership as the platform scales
