Job description

Software Engineers | San Francisco | Hybrid (3 days per week)

Do you want to build at the cutting edge of AI in a start-up that’s already won 25+ enterprise customers (with zero churn too)? If so, read on...

Aspiron has partnered with a fast-growing, series A Cybersecurity firm in San Francisco. They work to give security teams both visibility and confidence when working on large AI initiatives and roll outs.

Having just received their series A funding off the back of persistent growth, they’re now hiring a range of software engineers from mid-level to staff.

What you’ll be doing:

• Building the backend services and APIs at the heart of the platform
• Integrating with the biggest enterprise AI platforms and staying ahead as they evolve
• Turning huge volumes of activity data into clear, prioritised insight customers can act on
• Building in-house agents and LLM workflows, and pushing what’s possible with them
• Owning architecture, reliability and scale as the business takes off
• Working side by side with the founders, product and design, with a direct line to customers – functional skills needed

What they’re looking for

• Strong backend and platform engineering fundamentals
• Experience with some of Python, Node.js, Postgres and Azure (they’re language agnostic, and full-stack is a bonus)
• Genuine AI‑nativeness: you ship through automated review and CI/CD, not just prompt Claude, Codex or Cursor
• A real curiosity for agents, whether you’ve built them at work or played around with them in your spare time
• Start‑up experience and a hunger for ownership, pace and impact
• A customer‑first mindset: when something breaks for a customer, you want to be the one who fixes it so strong functional skills

You don’t need to have a background in cybersecurity for this role, albeit it does help.

The roles they’re hiring for:

• Software Engineer - $170 - $190k + equity
