Founding Engineer - Hire #2 - Funded US Startup

Read this first!!!!
This is a founding engineer role at an early-stage, funded startup growing ~50% month on month. It is not a 9-to-5. Expect long hours, occasional weekends, and real pressure to ship on client deadlines. In exchange you get ownership, outsized upside, and the chance to shape a company from the ground floor.
We're being blunt about the intensity on purpose. If you want predictable hours and firm boundaries, this isn't the role, and that's fine. If you're the kind of engineer who gets energised by shipping fast, owning outcomes, and building something that matters, keep reading.

What you'll do
Own our technical stack end-to-end: infrastructure, CI/CD, backend APIs, and front-end delivery.
Build and maintain scalable data pipelines (Python, DuckDB/MotherDuck, BigQuery, Postgres).
Design robust CI/CD workflows (GitHub Actions, Cloud Build, or similar) for rapid iteration.
Set up and manage core infrastructure (GCP or AWS): monitoring, logging, autoscaling, and security.
Build customer-facing features in TypeScript/React/Next.js with a strong focus on performance.
Work directly with the founders to define the roadmap, prioritise features, and make the technical calls that shape the company.
Contribute to hiring, technical standards, and engineering culture as we grow.

What you bring
Deep experience with infrastructure, CI/CD, and cloud platforms.
Strong skills in Python, Node.js/TypeScript, and SQL.
Comfort working with large datasets and optimising query performance.
Ability to architect systems from scratch, not just maintain them.
Startup mentality: proactive, resourceful, thrives in ambiguity.
Genuinely up for the hours and intensity of an early-stage startup, including crunch periods around launches and client deadlines.
Bonus: experience with data products, open data, or analytics tooling.
