Job Description

Principal Engineer at VC backed start-up

About the Company:

We’re a well-backed, early-stage tech venture on a mission to transform how people and intelligent systems work together. Our platform brings automation, data, and decision-making into one seamless experience — helping teams move faster, think smarter, and create more impact.

Supported by top-tier investors and already seeing strong early adoption, we’re scaling rapidly and looking for curious builders who want to help shape what comes next.

The Opportunity

You’ll be joining at a formative stage, working alongside the founding team to design, build, and scale the systems that will underpin our platform. This is not a role for spectators — you’ll have real influence over architecture, direction, and company growth.

We won’t box this role into a single title — we’re looking for someone who can span disciplines, adapt quickly, and thrive in a fast-moving, creative environment.

What You’ll Do

• Build, test, and deliver key components that shape our product experience
• Help define our technical direction, strategy, and long-term roadmap
• Collaborate directly with founders on product, design, and execution
• Influence the early company culture and future team structure

What We’re Looking For

• Solid hands-on experience building and scaling software systems
• Comfort working across different layers of the stack or learning as you go
• A mindset that values problem-solving, curiosity, and autonomy
• Someone excited by ambiguity, ownership, and genuine product impact
• Previous exposure to fast-moving or early-stage environments

(Experience in modern or frameworks is great — but we care more about how you think and build than what tools you’ve used.)

What’s on Offer

• Competitive pay and meaningful ownership
• High trust, flexibility, and autonomy in how you work
• A collaborative, low-ego environment built for growth and creativity
• The opportunity to help shape a next- technology company from the ground up
