Engineering
Service and interface work on a typed stack: commercial logic, contract management, financial calculation and integration. Correctness matters more than throughput here.
Home/Careers
Careers
Small team. Real ownership. No spectators.
TESSMA is built by a small group where every person owns a function end to end. That is the appeal and it is also the demand — there is nowhere to hide in a team this size.
Open roles
Current openings.
Live vacancies are listed here with title, function, location and reporting line as they open. We do not post roles we are not actively hiring for, and we do not collect speculative applications into a pipeline we never contact. If nothing is listed, nothing is open — but a specific, well-argued email is always read.
Functions
The disciplines this platform needs.
When we hire, it is into one of these. Useful context if you are considering writing to us before a role is posted.
Revenue & commercial
People who have priced real inventory and defended it to an owner. Product decisions in TESSMA come from this experience, not from a requirements document.
Contracting & partnerships
Negotiating supply and demand agreements, and turning them into structured terms the system can sell from correctly.
Finance
Reconciliation, settlement, tax treatment and financial controls inside a platform where money moves between parties.
Client delivery
Implementation and ongoing ownership of client relationships, from contract modelling through to quarterly review.
Product & design
Interfaces for people under time pressure who will be held accountable for the number on screen. Clarity over decoration.
How we hire
Four conversations. No trick questions.
01
A written exchange
You tell us what you have built or run, specifically. We reply with an honest read on fit before taking your time.
02
A real problem
Something drawn from our actual backlog, scoped to a couple of hours. Paid if it takes longer than that.
03
The team
Conversations with the people you would work beside daily, including whoever would depend on your work.
04
Terms in writing
Scope, reporting line, compensation and what success looks like at six months — before you decide.
Tell us what you would own.
Not a cover letter. One paragraph on the part of this you would take responsibility for, and why you are equipped to.
