Infrastructure Engineer

Join WRITER, a company on a mission to expand human capacity with superintelligence. As an Infrastructure Engineer, you will play a crucial role in ensuring the availability, performance, and reliability of our platform. You will work across various disciplines, design scalable infrastructure, and lead incident response and root-cause analyses. This is a unique opportunity to make a significant impact on our product roadmap and the success of our enterprise customers.

• Conception, design, and implementation of scalable, fault-tolerant infrastructure across multiple cloud platforms.
• Automation of operational tasks and infrastructure management using programming languages such as Python or Go.
• Ownership of the reliability, performance, and efficiency of core services, including defining and upholding service level objectives (SLOs).

• Breadth. Experience running containerisation in production (a real cluster, not a lab), with experience in Helm and Terraform or Pulumi on at least one major cloud (AWS preferred), plus good proficiency in Python or Go for automation and tooling
• Track record. 5+ years of experience in infrastructure engineering, DevOps, or a similar role focused on building and operating large-scale, high-availability production systems at a high-growth product company
• AI in workflow. AI is part of how you ship, not a thing you've read about — agentic tooling (Claude Code, Droid, Codex, internal skills) is in your daily loop, you've built or adopted AI-assisted workflows others now use, and you have strong opinions on where it's unreliable. This is a hard requirement, not a bonus. Candidates whose actual daily workflow does not already include AI tooling will not be advanced
• First-principles + decision-making. Demonstrated ability to Challenge the status quo, proactively identify systemic weaknesses, and propose innovative solutions to complex reliability problems — reason from constraints and failure modes (not analogy or vendor defaults), name the tradeoff in business terms (reliability vs. velocity, cost vs. blast radius, standardisation vs. one-off), and reject the "best practices" answer when it doesn't fit the problem
• Reversibility & blast-radius. Make reversible calls by default — write the rollback before you touch production, work fluently with monitoring and logging stacks (Prometheus, Grafana, ELK or equivalent), and stress the system in safe places so it comes back stronger
• Autonomy & end-to-end ownership. A strong sense of ownership and accountability, eager to Own mission-critical systems and drive them toward peak performance and unparalleled reliability. At least one 0-to-1 infrastructure build you owned end-to-end, with the outcome metric attached
• Cross-functional collaboration. Excellent communication, collaboration, and problem-solving skills, with a talent for building strong relationships and Connecting with cross-functional teams — surface non-goals before anyone asks, and partner with product, security, and platform peers as one delivery surface
• Software-engineering depth. A software-engineering background, not only config and scripting — you've designed, built, and shipped non-trivial production code (services, libraries, internal frameworks) in Python, Go, or a comparable language, you can read and modify the codebases your infrastructure runs, and you move between infra automation and feature engineering without changing brains
