Senior Backend Engineer (Rust)

About Inco

Inco is building the confidentiality layer for blockchains through encryption technologies. We’re building the next generation of secure, scalable, and privacy-enhancing solutions to web 3 that empower fintech, payments, and blockchain applications to have the same confidentiality and capabilities of web 2.

Who You Are

We’re looking for a senior backend engineer with strong production experience in Rust who thrives on solving complex problems and building performant systems end-to-end. You understand how to optimize backend systems at scale, and you take full ownership of features from architecture and design to deployment and monitoring.

We're looking for someone with a genuine engineering mindset - you're deeply curious about how things work under the hood and passionate about building robust, elegant solutions. You take ownership of your work from conception to production, treating infrastructure as a craft. You have an innate desire to build and improve systems, not just maintain them. You're the type of person who investigates root causes rather than applying quick fixes, and you get satisfaction from solving complex distributed systems challenges. You thrive in environments where you can dive deep into technical problems while maintaining a holistic view of the infrastructure landscape.

This role is hybrid, requiring at least 3 days a week in our Bangalore office.

Responsibilities

• Backend Architecture & Development
  
  • Design, build, and maintain production-level backend services in Rust.
    
  • Own systems end-to-end: from database schema and APIs to monitoring and scaling.
    
  • Drive optimization of performance, latency, and reliability across backend services.
    
    
• Leadership & Ownership
  
  • Take complete responsibility for backend systems, ensuring code quality, security, and scalability.
    
  • Lead technical design discussions, code reviews, and mentoring of junior engineers.
    
  • Collaborate closely with protocol, DevOps, and product teams to align backend with overall architecture.

• • Ensure security and reliability in a high-stakes environment where correctness matters.
    
    

• Web3 & Distributed Systems
  
  • Bonus: Design and implement backend services that integrate with blockchain infrastructure (Ethereum, Solana, etc.).
    
  • Bonus: Contribute to new product features at the intersection of Web3 and privacy-preserving technologies.
    
    
• Collaboration & Communication
  
  • Work closely with cross-functional teams to deliver features on time.
    
  • Communicate tradeoffs, timelines, and progress clearly.
    
  • Maintain strong documentation practices to ensure knowledge sharing.
    
    

Required Experience

• 3-5+ years backend engineering experience, with deep expertise in Rust.
  
• Proven track record of production-level backend systems running at scale.
  
• Strong understanding of system optimization (latency, throughput, memory, concurrency).
  
• Experience with databases (Postgres, Redis, or similar) and API design (REST/GraphQL).
  
• Strong grasp of distributed systems concepts and production debugging.
  
• Excellent communication skills and a history of clear cross-team collaboration.
  
• Startup mindset: able to own projects end-to-end and thrive in ambiguity.
  
• Based in Bangalore, with ability to work at least 3 days/week onsite.
  

Preferred Qualifications

• Experience building Web3, crypto, or blockchain-based systems.
  
• Familiarity with secure compute, privacy-preserving systems, or cryptography.
  
• Experience with DevOps practices (CI/CD, containerization, monitoring).
  
• Leadership experience mentoring engineers or leading projects.
  
• Open-source contributions in backend, infrastructure, or crypto projects.
