You'll join a small pod, sometimes with a PM and sometimes without, and own features end-to-end. From a fuzzy idea on Monday to something live and learning by Friday. No waiting for perfect specs. No handing off the hard parts to someone else.

What You’ll Own:

• Owning ecommerce features or product lines like Email/SMS/RCS end-to-end, from fuzzy idea to live in production.
• Writing backend services in Python and Go, plus the bits of PHP still around.
• Touching the frontend when the feature needs it.
• Talking to users, prototyping fast, and deciding what's good enough for v1.
• Making scope and trade-off calls inside the pod, then sanity-checking them with the wider team.
• Carrying the product thinking for yourself.
• Pushing for quality where it matters (reliability, performance), without gold-plating.

What We're Looking For:

• 5+ years of direct experience shipping something a real user touched, and you can speak to why it mattered to them, not just how you built it.
• Strong in Python and Go. Comfortable around PHP. Willing to work on the frontend when needed.
• SaaS or B2B background; you understand multi-tenant products and customer workflows.
• Have a coding agent as a daily driver, not weekend tinkering. You know where AI helps and where it gets in the way.
• Strong product instincts: opinions you can defend, and the humility to change them when data says otherwise.
• Comfortable in small autonomous teams with little process.
• Clear writer. Matters a lot in a distributed setup.
• Nice to have: ecommerce background, early-stage experience, or familiarity with email / CRM / marketing automation.

This role is for you if:

• You'd rather build the tool than wait for it.
• You've shipped in ambiguous environments and enjoyed it.
• You want to use AI to drive real business outcomes, not just build cool tech.
• You're obsessed with quality and craft, and you're figuring out how AI changes both.

This role is not for you if:

• You need detailed specs and clear boundaries to be productive.
• You haven't built AI tools into how you work.
• You struggle to express your reasoning clearly in writing.
• You'd rather specialise narrowly than be useful across the stack.
