Web3 Senior Software Engineer (Backend) (Full Remote, Global)

MarginFi / Project 0 is seeking a Senior Backend Engineer to design and build the next generation of risk analysis, monitoring, and solvency protection systems. This role sits at the intersection of quantitative reasoning, protocol mechanics, and real-time market intelligence.

While Solana experience is preferred, candidates from other Web3 ecosystems (e.g. Solidity, WASM-based runtimes) are encouraged to apply. Experience in finance, DeFi, or quantitative engineering is also beneficial.

Qualifications:

• 2+ years of Rust experience

• 2-5 years experience with data pipelines (Sqlmesh, DBT, or others)

• Strong quantitative skills: comfortable reasoning about complex system behaviors, risk models, and advanced calculations.

• Startup mindset: bias toward ownership, adaptability, and shipping high-quality work quickly.

Nice-To-Haves:

• 1+ years of hands-on Solana development

• Infrastructure and Kubernetes Experience (IaC, Terraform, Pulumi) preferred.

• Web3 fundamentals: solid grasp of core blockchain concepts (accounts, programs, oracles, cross-program invocation, cryptography basics, etc.).

• Experience with DeFi protocols, risk engines, or on-chain financial primitives.

• Contributions to open-source Defi or Blockchain projects.

• Typescript experience, especially around integrating with smart contracts.

Role:

• Work on data pipelines, infrastructure, and other backend applications. Process data into meaningful displays that drive business decision making

• Build and maintain risk analysis systems that detect, model, and respond to market conditions affecting protocol solvency.

• Shape the data ingestion pipeline and act as an early consumer of risk, market, and on-chain data.

• Generate actionable insights and automated alerts based on real-time market events, protocol activity, or systemic risk patterns.

• Improve backend-adjacent operational workflows, such as token rebalancing, liquidation planning, and treasury/free-funds management

Working at P0 has many perks, including: competitive salary, equity, token allocation, full benefits, unlimited PTO, and more.
