Job description

About WRITER

WRITER is where the world's leading enterprises orchestrate AI‑powered work. Our vision is to expand human capacity through superintelligence, and we prove it by delivering trustworthy AI that unites IT and business teams and unlocks enterprise‑wide transformation. With WRITER's end‑to‑end platform, hundreds of companies such as Mars, Marriott, Uber, and Vanguard build and deploy AI agents grounded in their own data and powered by WRITER's enterprise‑grade LLMs. Valued at $1.9B and backed by industry leaders, WRITER is rapidly cementing its position as the leader in enterprise generative AI.

Founded in 2020 with office hubs in San Francisco, New York City, Seattle, Austin, Chicago, and London, our team thinks big, moves fast, and welcomes smart builders and scalers to help shape the future of work with AI.

About the role

At WRITER, our mission to expand human capacity with superintelligence relies on a foundational truth: our platform must be available, performant, and reliable 24/7. As an Infrastructure Engineer you will be at the heart of making this a reality, impacting every enterprise customer who trusts us with their AI‑powered workflows. This role focuses on building resilient systems, automating across the stack, and championing reliability best practices, directly enabling our product roadmap and ensuring our customers always have access to the powerful tools they need.

This hybrid position is based out of our New York City, San Francisco, Seattle, or London hub. You will report to our Director of Engineering.

What you will do

Technical

• Breadth across disciplines. Focus deeply on one problem at a time while moving between SRE, DevOps, Infrastructure, and Platform work as priorities shift. Most of the time you will be heads‑down on a substantial initiative such as on‑call posture, release pipeline, multi‑region Terraform layout, or an internal platform surface.
• Simplicity / via negativa. Challenge the status quo and remove toil before adding new features. Automate operational tasks and infrastructure management with Python or Go, reject tools that don’t fit the problem, and treat manual on‑call work as a defect to be designed out.
• Breadth across the stack. Design scalable, fault‑tolerant infrastructure across AWS (preferred), GCP, and Azure, working fluently across Kubernetes, Helm, Terraform, and the supporting cloud and AI tooling that backs WRITER's high‑traffic platform.
• AI in workflow. Run agents in your daily loop—Claude Code, Droid, Codex, internal skills—to investigate incidents, draft Terraform/Helm changes, write runbooks, scaffold tooling, and review PRs. Build an agentic setup that lets humans and digital teammates work as one unified team, sharing skills, context, and on‑call workflows.
• Debugging fluency. Lead incident response, post‑mortems, and root‑cause analyses—trace failures to the underlying problem rather than symptoms, apply lessons back into architecture, and prevent the same incident from happening again.

Non‑technical

• End‑to‑end ownership. Own the reliability, performance, and efficiency of WRITER's core services end‑to‑end—define and uphold SLOs and error budgets, carry the on‑call pager, and stand behind outcome metrics.
• Strategic vs. tactical balance. Balance urgent work with 6–12‑month platform direction—ship the on‑call‑driving fix today while shaping multi‑year observability, cost, and reliability investments that move WRITER’s enterprise customers.
• Cross‑functional collaboration. Operate at the seams with product, security, and engineering peers, providing expert guidance on system design for reliability, performance, and scalability from conception through launch, connecting the infra agenda to product and revenue context, and disagreeing with evidence—not volume.

What you need

Technical

• 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.
• Breadth. Experience running containerisation in production, with Helm and Terraform or Pulumi on at least one major cloud (AWS preferred), plus good proficiency in Python or Go for automation and tooling.
• AI in workflow. AI is part of how you ship, not just a concept—agentic tooling such as Claude Code, Droid, Codex, and internal skills is used daily. Candidates who do not already employ AI tooling in their workflow 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, name trade‑offs in business terms, and reject “best practices” when they don’t fit the problem.
• Reversibility & blast‑radius. Make reversible calls by default—write rollback before touching production, work fluently with monitoring and logging stacks (Prometheus, Grafana, ELK or equivalent), and stress the system in safe places to strengthen it.

Non‑technical

• 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 proactively and partner with product, security, and platform peers as one delivery surface.
• Autonomy & end‑to‑end ownership. A strong sense of ownership and accountability, eagerness to own mission‑critical systems and drive them toward peak performance and unparalleled reliability. At least one 0‑to‑1 infrastructure build owned end‑to‑end, with outcome metrics attached, is required.

Bonus if you have

• Software‑engineering depth. A background in software engineering, not just configuration and scripting—designed, built, and shipped non‑trivial production code (services, libraries, internal frameworks) in Python, Go, or a comparable language, able to read and modify the codebases your infrastructure runs, and able to move between infra automation and feature engineering seamlessly.

Benefits & perks (US Full‑time employees)

• Generous PTO, plus company holidays
• Medical, dental, and vision coverage for you and your family
• Paid parental leave for all parents (16 weeks)
• Fertility and family planning support
• Early‑detection cancer testing through Galleri
• Flexible spending account and dependent FSA options
• Health savings account for eligible plans with company contribution
• Annual work‑life stipends for:
  • Wellness stipend for gym, massage/chiropractor, personal training, etc.
  • Learning and development stipend
• Company‑wide off‑sites and team off‑sites
• Competitive compensation, company stock options and 401k
