About The Opportunity We are hiring a Senior Software Engineer to join our founding engineering team and play a critical role in shaping Chainloop’s backend services, engineering culture, and long‑term product direction. This is an opportunity to build foundational systems in Go, influence architecture decisions, and set engineering standards at an early‑stage, high‑ambition startup focused on security and software supply chain excellence. You will work in an async‑first, ownership‑driven environment where clarity, autonomy, and impact matter more than meetings. If you enjoy building complex backend systems, shaping culture, and delivering high‑quality work at speed, this role is for you. What You Will Do Join the founding engineering team and contribute to the core technical vision of Chainloop. Architect, develop, and scale complex backend services primarily in Go. Own projects end‑to‑end, from initial design and technical planning to implementation, deployment, and production monitoring. Work in a fast‑moving, async‑first startup culture with high autonomy and accountability. Implement and champion best practices in software supply chain security, automation, reliability, and performance. Drive clarity from ambiguity by breaking down broad ideas into actionable engineering plans. Mentor teammates, review code thoughtfully, and help hire and level‑up future engineers. Requirements 10+ years of experience designing, building, and maintaining complex backend systems. Prior experience working in early‑stage products or startups is a strong plus. Strong, hands‑on experience with Go, or deep backend experience with a strong desire to learn Go. Proven experience owning the full lifecycle of backend features and services. Solid understanding of distributed systems, API design, performance optimization, and cloud‑native architectures. Strong written communication skills and ability to thrive in an async‑first environment. A practical understanding of modern software supply chains and security principles (or interest in learning deeply). How You Work: Dos (What We Expect) Own work end‑to‑end: From architectural design to production monitoring. Communicate async‑first: Write clearly, proactively, and with context. Drive clarity: Turn vague problems into structured, actionable plans. Raise the bar: Mentor others, review code thoughtfully, and help build an exceptional team. Champion security & quality: Deliver fast, safely, and with intention. Use AI & automation: Increase output, reliability, and impact through smart tooling. How You Should Not Work: Don’ts (Anti‑Patterns) Avoid unnecessary meetings: Use sync time only for decisions that truly require it. Don’t sacrifice quality for speed: Move fast, but never recklessly. Don’t stay silent: Speak up when misaligned, unclear, or when there’s a better path. Don’t expect rigid schedules: Flexibility is key, but commitment to deadlines is essential.
