Senior Django Engineer – Payments & Subscriptions | Contract | Remote EU | €550/day | Immediate Start

I'm working with a fast-scaling AI product company (millions of users across mobile, web and API products) that needs a senior Django contractor to take ownership of the pricing and subscription system at the core of their revenue.

This is a genuinely high-ownership role: architecture through to shipped code through to watching your releases perform in production. Small senior team, direct CTO exposure, backend deployed multiple times a week.

The work

Own the delivery and architecture of the pricing system used by every product surface and millions of users
Optimise existing endpoints — drive down latency, keep it scaling as usage grows
Design endpoints in direct collaboration with frontend engineers, with OpenAPI specs and supporting docs
Monitor your own releases (Datadog) and iterate fast on real usage data
Work cross-functionally with product and frontend to ship seamless user experiences

You'll need

5+ years of hands-on Django and Django Rest Framework — this is a hard requirement, not "Python with some Django exposure"
Relational databases at real scale: schema design, Django query optimisation, zero-downtime migrations on PostgreSQL/MySQL databases 100GB+
Production experience with subscription and billing infrastructure — Stripe and/or RevenueCat
A pragmatic, ship-fast mindset: speed of iteration over perfection, frameworks over reinvention
Strong ownership — comfortable making product and technical decisions without hand-holding
Fluent English
Available to start within 1–2 weeks

Details

Contract, initial 3–6 months, strong likelihood of extension
Rate: €550/day
Fully remote (EU-based), occasional overlap with CET hours
Fast process: short interview loop, quick decision

If you've built or scaled billing and subscription systems in Django for a high-volume consumer product, I'd like to speak with you this week. Message me directly or apply with a current CV.
