Our client is a rapidly growing startup focused on fundamentally improving security and flexibility in the Web3 ecosystem.
The company is developing a revolutionary API-driven key management solution designed to handle the critical foundational security challenges of decentralised applications.
We are seeking backend engineers who view security as a feature, not an afterthought. You are expected to be a systems thinker, comfortable solving entirely novel problems at the intersection of cryptography, cloud infrastructure, and distributed systems. While we ship code in Go, Typescript, and Rust, your core engineering fundamentals and ability to build scalable, resilient systems are what truly matter.
Your Impact:
- Secure by Design: You won't just maintain existing systems; you will be the primary builder of critical new ones.
- Security-First Architecture: Design and forge core infrastructure where usability meets uncompromised security—no corners cut.
- Cryptographic Systems: Develop and deploy the signing infrastructure and applications running within secure computing enclaves.
- Product Ownership: Drive the core product lifecycle, from writing detailed internal specifications and developer documentation to shipping features end-to-end, directly responding to customer needs.
- Scaling Excellence: Contribute to thoughtful deployment pipelines and infrastructure that radically reduce risk in mission-critical environments.
- Team Growth: Help shape the future engineering team through mentorship and process development.
The Profile: Systems Thinker & Security Guardian
- The Track Record: 5+ years of production experience shipping high-stakes infrastructure.
- The Tools: Hands-on experience with at least one of our core languages: Go, Typescript, or Rust.
- The Cloud: Deep familiarity with modern cloud providers (AWS, GCP, etc.) and deployment paradigms.
- The Mindset: A strong architectural viewpoint on how large-scale, resilient, and mission-critical systems should be built and operated.
- The Prerequisite: A naturally high standard for operational security, often described as a healthy dose of paranoia.
- Bonus Points: Prior experience building scaled products in the crypto/Web3 ecosystem.
Style Points: The Edge
- Secure Hardware: Experience developing against trusted execution environments (TEEs, HSMs).
- OS Mastery: A profound understanding of the Linux operating system and strategies for hardening the application surface area.
- Advanced Crypto: Expertise in threshold signing systems and a desire to be at the vanguard of production-grade cryptography.
- Ecosystem Insight: Actively tracking and forming opinionated viewpoints on where the crypto industry is headed.
