Job Description:

Build Bold Technology. Make a Meaningful Impact.

Are you an experienced software engineer looking for more purpose in your work?

Do you thrive in dynamic, start-up environments where your voice and skills truly matter?

Excited by the idea of developing cutting-edge products that push boundaries and deliver real-world change?

If this sounds like you – read on.

Why This Role is Great

Our client is a fast-growing Tech for Good start-up, born from world-class research and backed by serious ambition. They're developing a next-generation hardware-software product that combines deep tech innovation with real human impact. As part of a small, highly capable team, you’ll work at the forefront of product engineering - influencing architecture, driving standards, and helping scale the solution to market.

This is a role for someone who wants to build, not just maintain. Someone who wants to own problems, not just follow tickets.

Here’s what you’ll get to do:

• Contribute to the design and development of a groundbreaking new product from the ground up.
• Take a lead role in shaping the software architecture across the entire stack.
• Collaborate with cross-functional teams including UX, hardware, compliance and product.
• Code with clarity, scalability and maintainability in mind – always thinking a few steps ahead.
• Pair-program and mentor, helping to grow a strong internal engineering culture.
• Roll up your sleeves and thrive in the ambiguity and excitement that early-stage tech brings.

About You

This role is ideal for someone who enjoys autonomy, is energised by deep tech, and wants their work to mean something. You’ll be working with forward-thinking minds, solving technical challenges with elegance and purpose.

The wish list includes:

• Significant commercial experience in software engineering (5+ years ideal).
• A broad understanding of modern development practices, tools and full-stack architecture.
• Experience building mobile apps - Swift experience is a bonus, but not essential.
• Confidence working in Agile, collaborative environments.
• A strong grasp of engineering fundamentals - data structures, architecture, and clean code principles.
• Clear communication skills and a proactive, solutions-first mindset.
• Bonus points for a mathematical or analytical background - though curiosity and problem-solving are just as valuable.

Not 100% aligned? If you’re excited about the mission and have transferable skills, we encourage you to apply.

What’s in It for You

This is more than a job - it’s a chance to help shape the future of impactful technology.

• Flexible working hours with hybrid options available.
• Lunch (and dinner) provided when working late.
• Regular team outings and retreats - from outreach to off-sites.
• A location just minutes from a major tube line, with easy access to great facilities like a gym and climbing wall.
• Access to a fully equipped workshop with tools including 3D printers and CNC machines – open for professional or personal projects.

Diversity, Equity & Inclusion

Our client and Humand Talent Solutions are committed to building diverse and inclusive teams. We actively encourage applications from people of all backgrounds, identities, and experiences. If you believe you’d thrive in this environment, we want to hear from you - even if you’re not sure you meet every point.
