Your tasks

Job Intro

As a Senior Software Engineer on the Infrastructure team, you will play a key role in designing, developing, and maintaining the libraries and services that power off-chain data for the IOTA network. You will join a team of highly skilled software engineers dedicated to building efficient, scalable systems centered around a pipeline that captures and processes transaction data from the network in real time.

Responsibilities & Requirements

Architecture & API Development

• Lead the design and implementation of complex, production‑grade solutions for the off‑chain data layer of the IOTA network.
• Collaborate with core, language, DevOps, and other cross‑functional teams to align roadmaps, ensure architectural coherence, and meet technical‑strategy goals.
• Develop, document, and maintain versioned internal/external APIs (e.g., REST, gRPC, JSON‑RPC, GraphQL) with clear specification, and deprecation policies.

Performance & Scalability

• Optimize the ingestion pipeline for low latency and high throughput, processing millions of network transactions per day.
• Analyze and refactor relational schemas to improve query performance and write speed.

Code Quality & Technical Excellence

• Conduct rigorous code reviews, define coding standards, and advocate for best practices across the team.
• Advance the quality of our codebase by being proactive about reducing technical debt.
• Write code that works correctly, is easy to read and modify, interacts gracefully with users, and uses resources efficiently.

Team Culture & Mentorship

• Provide constructive, respectful feedback that promotes psychological safety.
• Mentor engineers of all experience levels, fostering a culture of continuous learning and knowledge sharing.
• Own feature delivery from concept through production, taking end‑to‑end responsibility while working independently.

Documentation & Knowledge Sharing

• Write clear, data‑driven reports for benchmarks and debugging investigations, emphasizing actionable conclusions that can be reproduced by peers.
• Author precise GitHub issue descriptions for new features and bugs, outlining motivation, goals, and required acceptance criteria.
• Produce well‑structured proposals that articulate the problem statement, proposed solution, trade‑offs, and a high‑level implementation sketch, facilitating informed discussions within and across teams.

Skills & Qualifications

If you love writing idiomatic, maintainable, and efficient Rust code, enjoy sharing knowledge and insights to help colleagues grow, don't mind the occasional low-level plumbing to fix and improve components, and value autonomy, trust, and flat hierarchies, then this role is an ideal fit for you.

• 5+ years of professional software development experience, focused on large-scale backend systems.
• 3+ years of production-grade Rust programming.
• Bachelor’s or Master’s degree in Computer Science, Engineering, Mathematics, or a related field.
• Deep expertise with PostgreSQL (schema design, indexing, performance tuning).
• Strong experience in concurrent/asynchronous programming.
• Proven system-design and architecture skills, with emphasis on performance optimization and scalability.
• Experience building microservices and web APIs (e.g., REST, RPC, GraphQL).
• Demonstrated leadership and technical communication skills.
• Ability to evaluate, adopt, and promote new technologies.
• Strong ownership mindset.
• Proficiency with Git and Docker.

Nice to Have

• Demonstrated experience with blockchain indexing.
• Working knowledge of cloud storage/databases such as S3, DynamoDB, or Bigtable.
• Experience with the Move language (especially object-based smart contracts).
• Hands-on experience with the IOTA or Sui network.
