We are hiring high-caliber engineers with 3+ years of experience to build low-latency, high-throughput trading infrastructure in Rust, working directly under senior systems architects. This is a hands-on coding role on performance-critical systems — you will write, test, and ship the core code.

Responsibilities

1. Develop and maintain high-performance backend services in Rust under the guidance of senior engineers
2. Implement components of distributed, fault-tolerant systems handling high transaction volumes
3. Write extensive unit, property-based, and simulation tests for correctness-critical code - Profile and optimize code for latency, throughput, and memory efficiency - Participate in design discussions and rigorous code reviews
4. Debug and resolve issues in Linux-based production environments

Required Qualifications

1. B.Tech/M.Tech in Computer Science from an IIT or NIT (mandatory) - 3+ years of professional software development experience in Rust, C++, or Java/Go with systems-level work; strong Rust proficiency or demonstrated ability to attain it fast - Understanding of financial markets and trading systems — order books, order types, matching concepts, spot and derivatives (futures/options) basics; hands-on experience with trading, broking, or market data systems is a strong plus - Excellent computer science fundamentals — data structures, algorithms, operating systems, networking, concurrency
2. Solid grasp of multithreading and memory management; exposure to performance profiling and benchmarking
3. Understanding of distributed systems concepts — replication, consistency, message queues (Kafka/NATS or similar)
4. Experience with Linux, Git, and modern development workflows
5. Strong problem-solving ability and hunger to work on hard systems problems

Preferred

1. Competitive programming background (Codeforces/ICPC/CodeChef ratings welcome on the CV)
2. Personal or open-source Rust projects
3. Exposure to low-latency techniques — lock-free structures, zero-allocation design, binary protocols (SBE/Protobuf/FlatBuffers)
4. NISM certifications, trading experience (personal F&O/options trading counts), or coursework in financial engineering
5. Exposure to consensus algorithms (Raft), event sourcing, or deterministic testing

Growth Path

You will be mentored directly by senior systems engineers with deep exchange-infrastructure experience, with a defined progression to senior engineer ownership of subsystems within 18–24 months. This team is being built as a center of excellence in low-latency systems engineering in India.

Selection Process

1. Resume shortlisting (college + evidence of strong engineering: projects, CP ratings, internships)
2. Online DSA + systems assessment
3. Live coding round (Rust/C++, performance-oriented problem)
4. Systems and trading-concepts discussion round
5. Culture and ownership round with the senior engineer you will report to

We build production software: web products, internal tools, APIs, and on-chain systems when the product needs them.

You own the smart contracts. Design and write Solidity for tokens, access control, issuance, transfers, and ownership on EVM chains. Set roles, events, and pause or upgrade paths. Test and deploy with Hardhat or Foundry, including unit, integration, and fork tests. Work with Product and Backend on ABIs, upgrade plans, and production readiness. Prepare for audits, triage findings, and ship fixes. Keep contracts clear, maintainable, and reasonable on gas. Document the architecture, assumptions, and how to operate what you ship.

What you bring:

- Strong EVM knowledge: gas, storage, events, reentrancy, access control, and common vulnerability patterns

- Hardhat, Foundry, or similar, through deployment

- ERC-20, ERC-721, ERC-1155, Ownable or AccessControl, and proxy or upgrade patterns

- TypeScript or JavaScript for scripts and tests (ethers or viem)

- Production contracts, with care for tests, security, and code quality

- A bachelor's degree in computer science or equivalent experience

- Clear communication with a remote team, and the ability to explain design tradeoffs

- A self-starter who can ship with little supervision

Nice to have: audit work, OpenZeppelin, L2s, account abstraction, permissioned chains, indexing or transaction orchestration, formal verification or static analysis.
