Junior Software Engineer

Junior Software Engineer

Location: Hybrid (2 days per week in our Central London office)

Salary: £40,000 starting salary

Working Pattern: 4-day work week (Monday–Thursday) as standard

Our challenge

How do you ship high-impact new features, scale an enterprise platform during rapid growth, and build a resilient team where domain knowledge is widely shared? We’re looking for an intellectually curious junior engineer to dive in and help us tackle these problems. You won't just be handed isolated features to write in a silo - you’ll work across the entire stack, collaborating on everything from user-facing front-end experiences to the back-end services that power them.

About Neurosight

We stand at the intersection of neuroscience, psychometric testing, and business psychology. We're redefining what's possible through radical innovations in online behavioural and cognitive assessment - partnering with leading employers to deliver transformative hiring outcomes.

Following three years of rigorous R&D, we commercially launched in a phase of rapid growth, and our technology is the engine driving that momentum.

Our journey and context

We have recently undergone a significant technical transformation. As our client base expands, our focus is shifting toward three core engineering pillars:

• Enterprise-grade robustness: Maintaining and scaling our core architecture and cloud infrastructure to ensure the high reliability, security, and data integrity.
• Seamless integrations: Ensuring our corporate partners can connect their systems into our platform easily, securely, and with minimal friction.
• Internal automation and analytical tools: Creating and improving internal tools and dashboards that automate manual processes for our non-technical staff, helping the whole business operate efficiently.

Because we are a small team, you will get to work across all of these areas. As you ramp up and demonstrate your capabilities, you’ll have the opportunity to grow into owning specific areas of the software and leading key projects. And because this role will occasionally be client-facing, you will have the unique opportunity to see the direct impact of your development work on our enterprise partners.

The learning curve is steep - but it comes with a safety net. You’ll have direct mentorship and clear architectural guidance, so you can grow quickly without ever being left to struggle in isolation.

Our tech stack

• Application: Full-stack TypeScript (NestJS Backend and React Frontend)
• Data: PostgreSQL, Azure Table Storage, & Redis
• Infrastructure: Azure & Terraform

What you’ll bring

• Strong engineering mindset: You combine a natural curiosity about how software works under the hood with an instinct for structured, logical problem-solving
• A passion for building: A portfolio, personal projects, or open-source contributions that prove you love creating things outside of a classroom setting.
• Collaborative autonomy: You confidently take ownership of problems and try to solve them independently, while valuing and enjoying the opportunity to work collaboratively – you know when to raise your hand and leverage the team's expertise before getting blocked.
• A language-agnostic approach: You see languages and frameworks as tools to solve problems, not your identity. You’re excited to jump from React to NestJS, or pick up something entirely new.
• Clear communication: You can break down complex technical concepts and explain them simply – whether you're chatting with fellow engineers, internal teams, or external enterprise clients.

Nice to have

• Prior experience with React and TypeScript
• Exposure to an Object-Oriented Programming concepts

Salary and benefits

• £40,000 starting salary.
• 4-day work week as standard
• 6 weeks annual leave.
• Pension and share options.
• A dynamic work environment with genuine, rapid growth opportunities.
