Apply

For engineers

Assessed once, matched for years.

Most engineers re-prove themselves to every new client. Pass our assessment once and we match you to established UK companies as work comes up. We hold the contract, raise the invoice in your name, and handle the compliance, so you never chase a client for payment or negotiate your own terms.

Apply

No fees, ever. We are paid by the client, never by you.

We pay only into an account in your own name.

Why VERTX

Serious work, and a company that stands behind you.

VERTX is a managed engineering service, not a job board. We find the client, hold the contract, and stay accountable for the engagement, so your part is simply to do excellent work.

  • Real product work with established UK teams.
  • Long-term engagements, one client at a time.
  • We hold the contract and handle the administration.
  • Your rate and terms are in writing before your first day.

The bar

More than a great coder.

You are joining a network with a real bar. Every engineer is assessed before they join, and your level is assessed, not declared. We select for the four things that decide whether remote work actually succeeds.

  • Ownership

    You take a rough brief all the way to a shipped, tested result, without being chased.

  • Clear communication

    You explain your thinking clearly in English, so nothing is lost across a remote team.

  • Reliability

    You do what you say, on a cadence a client can plan a roadmap around.

  • Judgement

    You know a demo that impresses from a feature that holds up when customers depend on it.

The VERTX assessment steps: a conversation on camera, a practical technical assessment, a technical review with a senior engineer and a secure identity check

Assessed properly, once, and you keep your tools

The call

One conversation, not four rounds

  • On camera, with your identity documents to hand
  • We ask how you have handled real work, not brain teasers
  • Your English is assessed on the call, so there is nothing to sit afterwards

The build

You build, with your AI on

  • A real task, close to the work you would actually be given
  • Your own AI tools stay on, because that is how you work
  • You talk a senior engineer through what you did and why

We go deeper on the code you already wrote

  • Your own submission, handed back exactly as you left it
  • A recorded session with a senior engineer who did not set the task
  • The level is awarded by us, and we defend it to the client

ReactNext.jsTypeScriptNode.js

Fullstack Engineers

React, Next.js, TypeScript, Node.js

You ship whole features, from the interface a user touches to the services and data behind it. You are comfortable making decisions across the stack, you care about the product and not only the ticket, and you can be trusted to take something from a rough brief to a shipped, tested result.

Node.jsGoPythonPostgreSQL

Backend Engineers

Node.js, Go, Python, PostgreSQL

You design and run the systems everything else depends on. APIs, data models, queues, and the quiet reliability work that keeps a product fast and safe under real load. You think about failure modes and observability as part of normal delivery, not as an afterthought.

Apply for this role
PythonPyTorchFastAPIPostgreSQL

AI and ML Engineers

Python, PyTorch, FastAPI, PostgreSQL

You build with models in production, not in notebooks. Data pipelines, evaluation, retrieval, and shipping applied AI that earns its place in a real product. You can tell the difference between a demo that impresses and a feature that holds up when customers depend on it.

What we handle

The only thing you have to be is an engineer.

Most remote work asks you to be three people at once: the engineer, the salesperson and the accounts department. We take two of those off you, so the only thing you are ever judged on is the engineering.

  • No bidding and no proposals, we bring you the client.
  • Your work counts from day one, no unpaid trial.
  • You never negotiate money, your rate is set with us.
  • You never invoice or chase, the paperwork is ours.
