Vetted talent · AI-native roles · Circular economy engineering

Hire the engineers other marketplaces cannot find.

Pre-vetted software developers, AI agent engineers and Forward Deployed Engineers — plus a specialist practice in circular economy and Digital Product Passport engineering.

Hire Unicorn Developers is a curated marketplace for pre-vetted software developers, AI agent engineers and Forward Deployed Engineers. Send a brief and receive a ranked shortlist with the reasoning behind every match, usually within two business days. Engagements start from around sixty dollars per hour.

Why we exist

Three things the incumbents do not do

We are not trying to out-scale Upwork. We are trying to be correct about a narrower, harder set of roles.

  • A published vetting process

    Most platforms claim a percentage and show you nothing. Ours is written down stage by stage, including what we reject for and why.

  • AI-native roles as first-class products

    AI agent engineers, Forward Deployed Engineers, RAG and LLMOps specialists. Named, defined and assessed as distinct disciplines rather than lumped under "AI engineer".

  • Circular economy and DPP engineering

    EU ESPR, Digital Product Passports, EPCIS 2.0 traceability and life cycle assessment data. A vertical practically no hiring marketplace covers.

Hire by role

Fourteen roles, defined precisely

Each role page explains what the role actually does, the skills that matter, how to assess candidates, and what it typically costs.

  • AI Agent Engineers

    Engineers who build agent systems that survive contact with production traffic, real users and a real budget.

  • Forward Deployed Engineers

    Engineers who sit with your customer, understand the messy reality, and ship the integration that makes your product actually work for them.

  • RAG Engineers

    Retrieval specialists who keep answers grounded when your corpus grows from a thousand documents to ten million.

  • LLMOps Engineers

    Infrastructure engineers who keep dozens of models, thousands of requests per minute and a finite budget from colliding.

  • Machine Learning Engineers

    Engineers who take a model from a notebook to a service that stays accurate after the data drifts.

  • Full-Stack Engineers

    Engineers who own a feature from database schema through to the interface, and the tests that keep it working.

  • Backend Engineers

    Engineers who design service contracts carefully, handle concurrency correctly, and instrument everything they ship.

  • Frontend Engineers

    Engineers who treat performance budgets and accessibility as acceptance criteria rather than aspirations.

  • Data Engineers

    Engineers who make the numbers trustworthy, so decisions stop being arguments about whose dashboard is right.

  • Platform and DevOps Engineers

    Engineers who make deployment boring, so shipping stops being an event and becomes a routine.

  • Mobile Engineers

    Engineers who ship apps that feel native, work offline, and get through app review without drama.

  • Digital Product Passport Engineers

    Engineers who turn EU ESPR obligations into working identifier, data carrier and API infrastructure.

  • Circular Economy Systems Engineers

    Engineers who turn life cycle assessment, EPR and material flow requirements into systems that actually run.

  • Traceability Engineers

    Engineers who build supply chain evidence on open standards, so a claim can be checked rather than trusted.

How it works

From brief to first commit

No bidding, no unexplained shortlists, no black-box matching.

  1. Send a brief

    Describe what you need built, the skills involved, your budget ceiling and time-zone requirement. Free text is fine — the intake agent parses it.

  2. Get a scored shortlist

    Our matching engine scores every available engineer on skill overlap, role fit, seniority, rate and time-zone overlap, and shows you the breakdown.

  3. Review the evidence

    Every profile comes with the vetting record behind it: work samples reviewed, interview scorecards and verified references.

  4. Run a paid trial

    Start with a short paid engagement on real work. It is the only assessment that reliably predicts the following six months.

  5. Onboard and scale

    Contracts, time-zone overlap and onboarding are handled. Add engineers to the same engagement as the work grows.

Questions people ask before hiring

How do I hire a developer through Hire Unicorn Developers?

Send a written brief describing what you need built, the skills involved, your budget ceiling and your time-zone requirement. Our matching engine scores every available engineer against that brief and returns a ranked shortlist with a visible score breakdown, so you can see exactly why each candidate appeared.

What makes this different from Upwork or Toptal?

Upwork is an open bidding marketplace where you do the filtering. Toptal is curated but oriented around generalists. We publish our vetting process, specialise in AI-native roles such as AI agent engineers and Forward Deployed Engineers, and show the scoring behind every match rather than presenting an unexplained shortlist.

What is an AI agent engineer, and do I need one?

An AI agent engineer builds systems where a language model plans and acts through tools rather than only generating text. You need one when a prototype breaks unpredictably in production, when token spend is outgrowing the value delivered, or when you cannot tell whether a prompt change improved the system.

How much does it cost to hire an engineer here?

Rates depend on role, seniority and region. Mid-level generalist engineers typically start around sixty dollars per hour, senior specialists run roughly ninety to one hundred and fifty, and scarce roles such as Digital Product Passport engineers reach one hundred and seventy-five. Full bands are published on the pricing page.

How quickly can someone start?

A shortlist usually arrives within two business days of a complete brief. Interviews and a paid trial typically add one to two weeks. Most engagements begin between one and three weeks after the initial brief, depending on how quickly your side can interview.

Do you help with circular economy and Digital Product Passport work?

Yes. It is a deliberate specialism. We place engineers who implement EU ESPR-aligned Digital Product Passports, EPCIS 2.0 traceability, life cycle assessment data pipelines and Extended Producer Responsibility reporting — a category almost no general hiring marketplace covers with any depth.
