About hiring Solidity engineers

Everything to know before you hire Solidity talent

Speqto places Solidity specialists who are assessed on real work, not résumé keywords. This page explains what to look for when you hire Solidity talent, how we vet it and how an engagement runs.

What a strong Solidity specialist actually knows

Smart contracts are unforgiving. A strong Solidity developer thinks in invariants, writes the tests before the code is trusted, and knows the classic failures: reentrancy, unchecked external calls, oracle manipulation, signature replay and upgrade storage collisions. They use OpenZeppelin as a base and justify every deviation.

They also understand cost. Gas-aware design, storage layout and sensible event use make a protocol cheaper to run, and fuzz and invariant tests in Foundry or Hardhat prove the logic holds when users behave badly.

Why teams hire from Speqto

A bench, not a single freelancer

If an engineer is unavailable or the fit is wrong, a replacement comes from the same bench, with knowledge handed over.

How to hire

Hire Solidity talent in four steps

A short, low-risk path from your brief to a working engineer. If the first engineer is not right, we replace them.

  1. 1

    Share your brief

    Tell us the role, stack, hours overlap and how long you need the engineer. A 20-minute call is usually enough.

  2. 2

    Get vetted profiles

    In about two business days you receive candidates with assessment notes, code samples and availability.

  3. 3

    Interview and trial

    Speak to the engineers yourself. Start with a short paid trial and continue only if the fit is right.

  4. 4

    Onboard and ship

    Your engineer joins stand-ups and repositories, demos weekly and is backed by a delivery lead.

Included

Every engineer comes with

No hidden extras: the basics of a safe, managed engagement are part of the package.

  • NDA and IP assignment

    Signed before details are shared; everything built is yours.

  • Weekly progress reports

    Plain-language updates and a demo of working software.

  • Replacement from our bench

    If the fit is wrong, a new engineer joins with a proper handover.

  • Your tools and repositories

    Your Git, tickets and chat; we adapt to your process.

  • Equipment and payroll handled

    Hardware, leave and compliance stay with Speqto.

  • 30 days notice to scale

    Add engineers or release them as your roadmap changes.

How quickly can I hire a Solidity developer?

You receive vetted profiles in about two business days, and most engineers can start within a week of your confirmation.

How do you vet Solidity specialists?

Each candidate completes a practical assessment reviewed by a senior engineer, a code review exercise and a communication check before we propose them.

Who owns the code and IP?

You do. IP is assigned to you in the contract, and an NDA is available before any discussion of your product.

Can I try before I commit?

Yes. Start with a short paid trial period and keep going only if the fit is right.
