Byzantine Finance
This job is closed
Byzantine Finance connects the efficiency of web3 with the stability of web2 assets. We deliver modern digital credit to web2 institutions through a simple app and API, giving them access to safer yield, higher efficiency, and stronger security.Â
We’re hiring a top-tier freelancer to support several internal engineering projects. If the collaboration works well, this can grow into a full-time role.Â
You’ll help drive the evolution of our API layer and the off-chain systems that power it. Our vaults operate fully on-chain, but all our web2 distribution partners integrate through our API - and we need someone strong to take this part of the stack to the next level.
Qualifications needed:Â
- API development: Development in Rust with Axum, Diesel, and Alloy crates. Prior experience with these frameworks is required.
- Database design & optimization: Manage database schema migrations (using Diesel ORM). PostgreSQL knowledge (indexes, query tuning, schema design) is expected.
- CI/CD & Git workflow: Build and maintain GitHub Actions pipelines. Enforce clean Git practices, code reviews, and automated quality checks.
- DevOps & Infrastructure: Operate and evolve the AWS-based infrastructure using Terraform, Docker, and IaC methodologies. Ensure proper observability (logs, metrics, alerts) and maintain cost-efficient, reliable deployments.
- Cryptography & authentication: Strong understanding of asymmetric cryptography, key-pair signatures, and secure authentication workflows. Experience implementing or integrating public/private key–based API authenticators.
Great to have:
- Preferably some familiarity with Passkey / WebAuthn technologies and modern authentication standards.
- Blockchain standards: Strong understanding of blockchain fundamentals and EVM internals. Ability to read, interpret, and reason about Solidity smart contracts. Knowledge of ERC-20 and ERC-4626 token/asset management standards.
- EVM automation: Ability to build backend workflows that automate on-chain interactions (transactions, monitoring, on-chain state checks).
Looking forward to speaking to you soon!
