Software Engineer - Build complex software tools – Deep-Tech

If you’re the kind of engineer who thrives on solving very hard problems, is interested in compilers or debuggers, can write low level C code, and wants to work on novel technology that rewrites the rulebook for how software gets built - this might be the role you’ve been looking for.

A Cambridge based Deep-Tech company with a world-class team is looking for a low level / Systems Software Engineer that will be working with like minded others on new features for their core product.

They value technical excellence, creative problem-solving, and the kind of curiosity that means you’re always digging deeper and perhaps interested in how the OS works.

What you’ll do:

• Own core features and technical projects (mostly C on Linux) with some Python for UI

• Focus on code quality as part of development - reviewing, refactoring, and writing new features

• Collaborate with a top tier engineers doing everything from code reviews to complex bug hunts

• Solve intellectually stimulating problems

About you:

• You’re hands-on with C (systems or embedded) and Python. (If you’ve dived deep into debugger / compiler internals, JITs, kernel APIs, x86 or assembly – even better)

• You like low-level or embedded systems and aren’t afraid of the Linux scheduler

• You’re as comfortable thinking about the “big picture” architecture as you are grinding through tricky debugging

• You hold a Computer Science degree (or similar), but it’s your passion for elegant solutions and relentless curiosity that sets you apart

Why join us?

• Work on truly unique, industry-defining tech

• Collaborate with brilliant people who care deeply about what they build

• Shape products used by the world’s most important technology companies

• Office-based or hybrid role in Cambridge with one of the best company cultures around
