About the job
Software Engineer (Python) – Seed Stage
We’re working with an early-stage (seed) company building a technically ambitious core product. This is a true zero-to-one environment — systems are still being defined, not just scaled.
This is not a role for maintaining existing services. You’ll be building the foundations of the product alongside a small, high-calibre team.
What you’ll do?
- Own backend systems from design → build → deployment → operation
- Build Python services that form the core of the product
- Tackle non-trivial technical problems across performance, reliability, and data
- Work closely with founders and product to shape what gets built
- Continuously iterate on systems in a fast-moving environment
What makes this interesting?
- Zero-to-one: you’re building foundational systems, not iterating on mature infra
- High ownership: small team, real responsibility from day one
- Technical depth: problems go beyond simple CRUD or surface-level work
- Fast pace: decisions are made quickly, and you’ll see immediate impact
- Strong growth curve: steep learning environment with high expectations
What are we looking for?
- Strong backend engineers with solid Python experience
- Evidence of building and owning production systems (even small-scale)
- Ability to solve problems independently without a heavy structure
- High rate of learning and adaptability
- Engineers who want to build, not just contribute
