Senior Software Engineer

We are hiring an entrepreneurial and output driven Senior Software Engineer, to join our experienced and ambitious technical team. Reporting to our Engineering Manager, you will work on the front-end and back-end systems that drive Ash’s ability to feel personal, timely and human to users. This person will be an owner of their domain, developing and deploying products 0-1 with little oversight. You will be a core member of a team building a once in a generation product that will eventually serve 1 billion users.

If you are technically obsessed, care deeply about shipping products that matter most in a world of AI, and want to produce and deploy best in class code with a team driven by impact and outcomes, this role could be for you.

Key responsibilities:

• Build and own the systems that make Ash feel personal, timely, and human — including memory architecture (what Ash saves, retrieves, and forgets), notification logic (what to send, when, and why), conversation delivery (how messages are timed, split, and surfaced to users), and personalisation features that adapt to each user over time.
