About the role
What we're looking for
We need someone with roughly 3–6 years of software engineering experience, ideally at a well-regarded startup, fast-growing scale-up or top tech company, who has built something hard and shipped it to real users. That means software that ran in production, broke and got fixed, not a prototype. You should be comfortable sitting with enterprise customers, learning how they actually work and building full-stack software around it in a fast, in-person startup. You should also have a track record of turning messy real-world problems into production systems that people use. Bonus points if you've been a founder or on a founding team, worked as an early engineer at an EF, YC or Antler startup, or held a forward-deployed or solutions engineering role.
What you'll do
-
Work inside Seamflow's enterprise customers. These are some of the largest certification bodies, notified bodies and inspection companies in the testing, inspection and certification (TIC) industry. You'll join their calls, read their real documents and map how they actually run scheduling, technical review, conformity assessment and field inspection.
-
Own customer deployments from start to finish and make sure they deliver results. Every customer works differently and there's no template, so you decide what to build, build it and hear about it when it's wrong.
-
Work closely with the founders, the lead engineer and the CTO to turn what you learn in the field into product improvements, so that work done for one customer can be reused across the platform.
-
Build AI-powered workflows and document intelligence that pull structure and meaning out of messy Word documents, PDFs, spreadsheets and email, replacing the manual processes that keep the physical economy safe.
-
Lead work from first scoping call to production rollout. That covers the interface, the backend, the data model and the LLM/model layer. You'll ship to production in your first week.
-
Review and improve hundreds of real outputs to raise accuracy, reliability and customer adoption, with speed and good judgement about what not to build.
About you
-
A strong engineer first. Specific languages matter less than raw ability. Python plus some frontend counts as full-stack, but pure frontend profiles aren't a fit.
-
Personable, credible and confident in front of customers. If you haven't done forward-deployed work before but are a strong, customer-ready engineer, that's fine.
-
Driven to build from the ground up and take a lot of ownership. You don't want tickets handed to you each morning.
-
Able to work on-site in Shoreditch, London, five days a week. Visa sponsorship and relocation support are available.
About Seamflow
Seamflow is building the software layer for the testing, inspection and certification (TIC) industry — the invisible infrastructure that keeps the physical economy safe. Every plane, medical device, lift, battery and building has to be tested, inspected and certified before it reaches the world, and that entire process still runs on Word documents, PDFs, spreadsheets and email.
Seamflow builds AI-powered workflows for certification bodies, notified bodies and inspection companies, covering scheduling and resource planning, technical review, conformity assessment, field inspection, and document intelligence over messy real-world files.
Founded in 2025 and backed by a $4.5M seed round (14x oversubscribed), co-led by Northzone and Initialized Capital — the funds behind Spotify, Klarna, Coinbase and Reddit — Seamflow has gone from one customer a year ago to being deployed inside six of the ten largest enterprises in the industry. The company's valuation has quadrupled this year, and investors have already offered to lead a Series A.
Seamflow runs one of the most ambitious startup cultures in Europe: fast-paced, extremely high ownership, and in-person from their Shoreditch, London office. The team hires against a very high bar — engineering excellence is the number one priority — and the culture is defined by speed, taste, and a relentless focus on building systems that hold up in the real world.
