Red Stone is a fast-growing Polish blockchain startup revolutionizing oracle infrastructure. With our 45+ person team, including over 50% senior engineers, we deliver scalable, secure, and low-latency off‑chain data to smart contracts across multiple chains. We’ve secured over $6 B in TVS, raised $15 M in Series A funding, and were recognized by Forbes as the top VC-backed startup in Poland.
Backed by leading Web3 names like Arrington Capital, Stani Kulechov (Aave), and Gnosis, our team includes alumni from Google, Open Zeppelin, and major crypto projects. We work remotely across time zones, with a Warsaw HQ for deep work and collaboration.
About the Role
We’re looking for a Reliability Engineer — someone who sits at the intersection of backend engineering and Dev Ops. In this role, you’ll ensure the scalability, performance, and security of Red Stone’s oracle infrastructure by deploying, monitoring, and debugging critical services.
You’ll not only automate infrastructure and monitoring but also dive into the codebase (Node.js, Go, Rust) to debug, fix, and extend backend components when needed. This is a hands‑on, high‑impact position for an engineer who loves both clean architecture and resilient systems.
Blockchain: Solidity / Yul
Infra: AWS (ECS, EC2, Lambda, Cloud Watch, IAM, S3, Dynamo DB), GCP, Terraform, Docker
CI/CD: Git Hub Actions
Databases: Mongo DB
Frontend: Vue.js (hosted on Vercel)
Ensure high availability and reliability of Red Stone services across multiple chains and environments
Deploy and operate applications on AWS, GCP
Develop and maintain monitoring pipelines (Influx DB, Grafana, Cloud Watch, etc.)
Debug, fix, and extend backend services (mainly in Node.js, Go, and Rust)
Automate infrastructure tasks with Terraform, Docker, and CI/CD pipelines
Contribute to system and protocol design with a focus on performance and security
Conduct security reviews and performance profiling for both infra and backend code
Write clear documentation and internal tutorials for Dev Ops and debugging processes
✅ Job Requirements
5+ years of professional experience in software development and/or infrastructure engineering
Strong coding ability (preferably in Node.js, Go, or Rust) with proven debugging skills
Solid understanding of cloud platforms (AWS/GCP) and infrastructure as code (Terraform)
Familiarity with async/event-driven frameworks for data processing
Hands‑on experience with CI/CD pipelines (Git Hub Actions or similar)
Knowledge of monitoring, alerting, and performance profiling tools
Strong grasp of security best practices in distributed environments
Diligence, attention to detail, and strong problem‑solving mindset
Experience running and maintaining blockchain nodes
Background in Web3, De Fi, or blockchain protocols (sidechains, rollups, modular infra)
Participation in hackathons, programming competitions, or open-source projects
Experience with distributed systems and low‑latency architecture
Familiarity with the Solana ecosystem
What We Offer
Fully remote or hybrid work (Warsaw HQ at Zgoda 3)
Competitive salary + token allocation (after 3 months)
Flexible hours & pre‑agreed paid service breaks
Long‑term stability (Series A closed, backed by top investors)
Regular team off‑sites, hackathons, and Web3 events
Full ownership over your work & decisions
A rare opportunity to build foundational infrastructure for the future of finance
