Blockchain Engineer
Write and review smart contracts on EVM and Solana, build the Web3 products we develop in-house, and publish research under the Sanad Squad name.
The role
This is a junior-level position. We do not expect you to arrive with every skill listed below. What we expect is a solid technical foundation, genuine interest in blockchain security, and the ability to learn quickly, work independently, and take risks.
What you will do
- Develop smart contracts on EVM and Solana.
- Review smart contracts on EVM and Solana, and help produce clear, reproducible findings.
- Write technical articles on Web3, blockchain, and smart contract security for the Sanad Squad blog.
- Build and maintain our blockchain products. Develop features, work on the tooling, and see it through to delivery.
- Own what you ship, taking a product or tool from an idea to something clients and the community can use.
- Keep learning new blockchain and Web3 technologies as the space moves.
Training and onboarding
Before you start on real client and product work, you will go through a structured training period. The company covers your learning: courses and guided study in smart contract development, smart contract security, DeFi applications, and the other areas the role requires.
You will learn and work on your own, not lean on us. We support, guide, and wait. But you must be able to move forward, and move fast.
What you need
- Basic knowledge of blockchain and Web3 fundamentals.
- Solidity skills with some projects behind them, or Rust skills with some projects on Solana.
- Solid general software engineering and technical skills.
- Practical ability to use AI tools well in your day-to-day work.
- Willingness to learn fast, and to take feedback on your code and your findings.
- Good written English. A meaningful part of this role is writing.
Nice to have
- Smart contract development experience (EVM and/or Solana).
- Smart contract auditing or security review experience (EVM and/or Solana).
- Familiarity with x402 and MPP, or with agentic payments more broadly.
- Public work we can look at: audit reports, CTF or contest results, open-source contributions, or a technical blog.
What we offer
Pay
- Monthly retainer.
- A share of every project you work on, on top of the retainer. This is where the larger part of your income comes from, and your share grows as your work needs less review.
- Retention bonus on your 12-month date.
How we work
- Core hours are 12:00 to 16:00 Cairo, every working day. Online, reachable within about fifteen minutes, and ready to join a call.
- We count deadlines, not hours. Nobody tracks your time.
- You may work elsewhere, as long as you are present during core hours, you hit your deadlines, and you tell us in writing before you start.
Hiring process
Four stages, from a first conversation with both founders to an offer.
Interview with both founders
Basic information sharing and a vibe check.
Interview with each founder
Two separate interviews, one on the technical side, one on personality and soft skills.
Two-week trial
Normal hours, normal rules, unpaid. We write down what the two weeks should produce before you begin, and either side can stop at any point with nothing owed.
Offer
After two weeks, either you go on the retainer or we part cleanly.
