Senior Rust Engineer | Careers

About Fermah

We are building the next-gen infrastructure to enable next-gen apps.

If you want to help define how workflows of onchain/offchain computation become easily programmable, you might be a fit for Fermah.

What We Do

Fermah is backed by a16z CSX, Lemniscap, and other Tier-1 VCs.

Fermah has built a universal proof market that is currently live on Testnet.

The proof market connects two sides: • Compute suppliers offering hardware, mostly GPUs. • Devs and protocols that need fast, reliable, and cost-efficient proof generation.

Fermah’s orchestration layer is to proof generation what Uber is to rides. It optimally matches proof requests to machines. In fact, the proof market works for any proof system and any chain – making it a universal proof market, proudly serving customers including ZKsync, Scroll, and Gateway, among others.

We are now expanding to build the next-gen infrastructure (in stealth). That means bringing net-new users to blockchain, enabling developers to build applications that finally reach their full potential (instead of a web3 facelift for an otherwise web2 product), and erasing the woes of today’s developers as they spend inordinate amounts of time stitching networks together rather than focusing on actual business logic.

If you want to be a part of a team that gets stuff done like it’s no one’s business, we’d like to talk.

About Our Founder

Fermah was founded by Dr. Vanishree Rao. She has been designing and building ZK for over 15 years and has a PhD in cryptography from UCLA.

The role

We are seeking a seasoned Rust backend generalist to join our passionate engineering team that operates in an environment of shared accountability and without hierarchy. You will collaborate closely on the design with the team and co-lead the implementation, while helping to assimilate new members as we build out the necessary team.

As an early team member, you will help shape not only the protocol, but also who we are as a company. You will have the freedom and autonomy to shape the direction of our culture and platform, contributing your ideas and expertise to drive its evolution. You will be challenged with complex problem-solving.

Responsibilities

Work on the backend systems, including networking, infrastructure, node software, and client software.
Contribute to the protocol design as we progress through the SDLC and testing environments
Work on building the proving workload orchestration to distributed prover machines and other core protocol components of the network.
Provide technical co-leadership alongside the engineering team through a heavily hands-on mode of implementation.

What You Bring

Proven experience with Rust and its async libraries, particularly Tokio.
Strong understanding of RPC protocols, including HTTP and WebSocket APIs.
Extensive experience in backend blockchain development, including node and client software, as well as supporting infrastructure.
Familiarity with leading Web3 technologies, particularly the EVM and its surrounding ecosystem.
Demonstrated success in launching and developing greenfield projects.
A track record of building and participating on high-performance teams, fostering a culture of excellence and strong execution.

Nice-To-Haves

Proficiency in PostgreSQL and Rust ecosystem libraries like Diesel, SQLx, and SeaORM
Experience with containerization and orchestration tools such as Docker and Kubernetes
Familiarity with implementing and utilizing gRPC APIs
Experience with observability tools, specifically OpenTelemetry and metrics aggregation
Understanding of peer-to-peer networking concepts, including libp2p and Distributed Hash Tables (DHT)
Basic knowledge of cryptographic principles, including hash functions and pairing-based cryptography (ECDSA, BLS)
Basic knowledge of AWS and GCP

Benefits

Competitive salary and equity
Opportunity to work with a driven, talented, dedicated team that values collaboration, innovation, and making a strong positive impact
Culture built upon mutual respect, empathy, excellence and delivery
