This is a full-time, fully remote Smart Contract Developer role paying $138,000 a year, open to candidates anywhere. The team ships and maintains live smart contracts, and they need someone who can write one, break it on purpose to find the flaws, then defend it against the people who'll try to break it for real.
The listing title mentions freelance-style opportunities, but the actual arrangement here is full-time employment rather than per-project contract work. Worth clearing up early, since the two attract fairly different applicants, and the expectations around availability and ongoing ownership of the codebase differ too.
The work
- Write, test, and audit smart contracts for security and correctness
- Deploy contracts onto blockchain networks
- Troubleshoot issues in decentralized applications that are already live and being used
That last point matters more than it might sound. A bug in a live contract isn't something you patch quietly overnight; depending on the deployment, it might not be patchable at all without a migration, and funds could already be at risk by the time anyone notices. Last year, a lending protocol lost several million dollars because a reentrancy check was missing from a function that everyone assumed was covered by a shared library. This role exists to catch that kind of gap before it ships, not after.
Testing and auditing aren't phases that happen once at the end. Contracts get revisited whenever a dependency updates, whenever a new integration gets added, and whenever a similar protocol elsewhere gets exploited in a way that raises questions about your own codebase. The work is ongoing in a way that much application development isn't.
Skills required
- Solidity, at a level where you can read someone else's contract and spot the problem without a debugger
- Smart contract security, including familiarity with the common attack classes: reentrancy, integer overflow, access control gaps, oracle manipulation
- Working knowledge of blockchain protocols and how gas, consensus, and finality actually affect contract design
- Testing frameworks such as Hardhat or Foundry
- JavaScript, for tooling and integration work around the contracts themselves
A CertiK or Trail of Bits-style audit background will get an application a second look, and so will experience with formal verification tools like Certora. Neither is required. What actually gets someone hired is a portfolio of contracts they can walk through line by line and explain the tradeoffs on, not a certificate.
It's also worth being honest about what the JavaScript requirement actually covers. This isn't a full-stack role, and nobody's expecting deep frontend work. What comes up in practice is scripting for deployment, writing integration tests that call the contracts the way a real application would, and occasionally debugging why a frontend is reading contract state incorrectly.
Background and experience
Most people who land this role come in with a computer science degree, and the team treats that as the floor rather than a strict gate. Beyond that, candidates need real hands-on time writing and auditing smart contracts on blockchain platforms, not just coursework or a bootcamp certificate. Two years of that experience is the requirement, and contract security specifically needs to be strong; this isn't a role where "I can write Solidity" is enough on its own, since writing a contract that compiles and writing one that survives an adversarial audit are different skills entirely.
Freelance and contract-to-hire crypto developers sometimes assume a security-focused role like this one, thinking it's a stretch from general blockchain work, but the two overlap more than people expect. Someone who's shipped contracts and had to fix what an audit flagged usually already has the instincts this job asks for.
People coming from traditional backend security work sometimes transition into this space well too, since the underlying mindset, thinking like an attacker before a feature ships, carries over even though the tooling is completely different. What takes longer to build is the specific vocabulary for gas costs and on-chain state, which doesn't have a direct equivalent in conventional software.
Pay and benefits
The role pays $138,000 annually and is structured as a full-time position, not a per-project contract, even though these postings are sometimes labeled as such on job boards. Naukri Mitra lists this one under Fintech & Crypto alongside a handful of similar smart contract roles, and the pay here reflects the security emphasis rather than general development work. Someone weighing whether to become a remote smart contract developer or stay in general blockchain engineering should know that the security specialization is what moves the needle, not the remote arrangement itself.

What makes this different from general blockchain development
General blockchain development is about building things that work. This role is about building things that can't be made to fail on purpose, which is a narrower and less forgiving target. Every function you write gets read by someone actively looking for a way to drain it, and the review process reflects that; expect thorough code review, and expect to defend design decisions that a less adversarial environment would wave through without comment.
The upside is that the work stays interesting. Smart contract security doesn't have a settled playbook the way a lot of traditional software security does. New attack patterns emerge as new protocol designs are deployed, and staying current means actually reading post-mortems from other teams' incidents, not just following a checklist someone wrote two years ago. There's a genuine intellectual pull to it that pure feature-building work doesn't usually have, since every contract you audit teaches you something about how the last one broke.
How to apply
Send a resume along with links to contracts you've written or audited; GitHub is fine if the repos are public. If you've got a writeup of a vulnerability you found in a past project, include it; a walkthrough like that shows how you actually think about risk, which matters more here than a list of tools on a resume. There's no fixed application deadline, and candidates are reviewed as they come in rather than held for a batch cutoff.
