About the role

As a Senior Rust Software Engineer, this is a technically challenging, high-impact role for an experienced engineer who enjoys tackling bleeding-edge problems alongside other bright minds. You will have a significant influence on platform architecture and guide important technical and design decisions.

The team is unifying deterministic computation and performance to build a proof-generating virtual machine capable of running standard RISC-V Linux programs. This enables verifiable execution—ensuring that code runs exactly according to defined semantics, regardless of where it is executed.

You will work at the intersection of systems programming, performance engineering, and cryptographic verification, contributing to foundational infrastructure used across the Web3 ecosystem. Day-to-day activities include performance optimisation, designing commitment and proof schemes, low-level systems work, and building SDKs and tooling for other developers.

You'll join a team deeply embedded in blockchain and Web3 infrastructure, supporting decentralised applications, developer tooling, and platforms across areas such as DeFi, gaming, and digital culture. The work is built on an open-source blockchain known for its flexibility, security, and self-evolving capabilities, including Etherlink, an EVM-compatible Layer 2 that is rapidly scaling its developer ecosystem.

Responsibilities

Design and develop core components of a proof-generating virtual machine for RISC-V Linux programs
Apply systems programming and performance engineering techniques to optimise correctness and efficiency
Contribute to the design and evolution of commitment and proof schemes
Build and maintain SDKs and tooling for internal and external developers
Break down complex engineering problems into clear, tractable solutions
Participate in and influence key architectural and design decisions
Collaborate closely with other engineers in a fast-moving, research-driven environment
Communicate complex technical ideas clearly through writing, discussions, and whiteboarding

Requirements

Strong, hands-on experience in software engineering
Experience with modern, idiomatic Rust — or a strong motivation to learn it quickly
Solid computer science fundamentals, including: Algorithms, Data structures, Concurrency
Proven ability to reason about large systems and decompose complex problems
Clear communication skills in deep technical contexts (written and verbal)
Comfortable working with a high degree of autonomy and ownership
Passion for crypto, blockchain technology, and fast-paced engineering environments

Nice to have

Familiarity with instruction sets in different execution contexts
Experience working with language runtimes, compilers, or interpreters
Background in systems programming, embedded systems, or performance-critical software

Benefits

Fixed Shifts: 12:00 PM - 9:30 PM IST (Summer) | 1:00 PM - 10:30 PM IST (Winter)
No Weekend Work: Real work-life balance, not just words
Day 1 Benefits: Laptop and full medical insurance provided
Support That Matters:Mentorship, community, and forums where ideas are shared
True Belonging: A long-term career where your contributions are valued
