Company mission
To provide a permissionless, transparent, and fair ecosystem, for MEV extraction to reinforce the Ethereum ideals.
Role
Who you are
- Experienced Infrastructure Engineer: 4-10 years of experience with production systems and deep understanding of infrastructure, platform engineering, or DevOps concepts at scale
- Systems Programming Expert: Strong skills in Rust or Go, with the ability to build high-performance, secure systems
- Bonus points if you've contributed to execution layer/node projects like Geth, Reth, or rbuilder
- Excellent Communicator: Whether working independently or leading cross-functional teams, you have exceptional communication and coordination skills for our remote-first, global environment
- Impact-Driven: You're motivated by solving hard problems that have asymmetric impact and strike at the core of crypto's infrastructure challenges
Desirable
- Ethereum Infrastructure Experience: Experience running Ethereum infrastructure, such as clients, builders, rollup sequencers, or MEV-Boost components
- Open Source Contributions: Contributed to open-source infrastructure tooling or participated in protocol engineering discussions
- Trusted Execution Environments: Worked with TEEs, secure enclaves (like Intel TDX), or other trusted compute primitives - particularly relevant as we migrate our infrastructure to TEE-based systems
- High-Performance Systems: Built high-throughput or latency-sensitive systems (e.g., trading infrastructure, real-time data processing)
- Blockchain Ecosystem Knowledge: Deep understanding of MEV, L2 scaling solutions, or DeFi protocols
What the job involves
- Flashbots is searching for senior backend infrastructure engineers to join our growing L2 team
- In this role, you'll work on foundational infrastructure, tackle complex technical challenges, and work with industry leading experts across scaling, MEV, and DeFi
- Your contributions will shape flagship products like Rollup-Boost while driving forward essential open-source innovations
- Lead Infrastructure Development: Lead or support development of high-performance backend infrastructure for rollups, including block builders, sequencers, and decentralized execution environments powered by TEE technology
- Own Critical Infrastructure: Own key infrastructure components across CI/CD, observability, automation, and runtime performance tooling that support our production systems serving millions of users
- Cross-functional Collaboration: Collaborate closely with protocol, research, and backend teams to design infrastructure that balances fast UX with decentralization goals and censorship resistance
- Production Excellence: Debug production systems at the OS, network, or runtime level and drive reliability improvements across the stack to maintain our industry-leading uptime standards
- Open Source Leadership: Contribute to and lead open-source infrastructure projects that advance the MEV ecosystem and blockchain scalability
Our take
Flashbots is a research and development organization that is mitigating the miner-extractable value (MEV) problem, striving for a transparent and fair ecosystem for MEV extraction to reinforce the Ethereum blockchain ideals.
Flashbots, while connecting searchers and mining pools, stands out for not using private contracts and arrangements. Instead, it is an open participation system where any searcher or mining pool can join. This is considered more beneficial to the network, rather than a few private entities dominating because it still allows for competition.
The company is making notable strides, having raised $60M to fund the launch of Suave, an ambitious new project aimed at transforming the way blockchain operators earn value across different networks. With this, the company is becoming a genuinely exciting disrupter to an ever-changing industry. While things are still in motion, the company has ramped up its hiring efforts, signalling an exciting phase of growth and innovation ahead.
