Senior Software Engineer (EU)

Invert is Bioprocess AI Software purpose-built to accelerate the development of life-changing therapies and sustainable products. We unify fragmented bioprocess data into a real-time, AI-ready foundation that enables faster, more confident decisions — because delays in bioprocessing cost more than money.

Scientists today are too often forced to work in the dark. Critical data gets siloed across systems, delaying insight and increasing risk. Invert connects to bioreactors, instruments, and lab systems (LIMS, ELNs), continuously harmonizing time-series and offline data. Our built-in intelligence layer surfaces issues as they emerge, empowering teams to course-correct in real time — not after the damage is done.

We believe scientific expertise should drive innovation, not get lost in spreadsheets. We're building software that enables biotech teams to operate with the speed their work deserves.

You will be joining one of our European engineering teams to tackle some of the most challenging product-based engineering questions we face today. Here is what we are building on:

• Backend: Python, FastAPI, and PostgreSQL

• Infrastructure: Terraform IaC hosted on AWS

• Frontend: Next.js with TypeScript and TailwindCSS hosted on Vercel

• Collaboration tools: GitHub, Linear, Slack, Notion

As a Senior Software Engineer, you will ensure that your team efficiently ships new features that meet the specifications and standards set by our Product team. Additionally, you will ensure that your team makes sound technical decisions that allow us to sustainably scale our user base and the surface area of our products.
