FORTA Concrete Fiber

Backend Engineer

• In this role, you will play an essential part in building new components, communicating with our users to gather feedback, and working collaboratively with the rest of the team to make sure we solve important problems and provide a great user experience.
• Lead critical projects end-to-end: design docs, implementation in Go/Solidity, reviews, rollouts, and post-mortems.
• Build sequencer-adjacent services: screening APIs, proxies, attestations, and chain integrations (OP Stack/Arbitrum).
• Deep dive on performance: profiling, load tests, flamegraphs, cache/queue tuning, and data-path optimizations.
• Security first: threat modeling, key/secret management, IAM, least-privilege, audit/readiness practices.
• Operational excellence: on-call participation, incident response, blameless retros, runbooks.
• Mentor & multiply: guide teammates through designs, reviews, testing standards, and best practices.
• Ecosystem awareness: track EVM/OP/Arbitrum changes, block building patterns, and bring actionable insights.
