About WRITER

WRITER is where the world's leading enterprises orchestrate AI-powered work. And we're proving it's possible – through powerful, trustworthy AI that unites IT and business teams together to unlock enterprise-wide transformation. With WRITER's end-to-end platform, hundreds of companies like Mars, Marriott, Uber, and Vanguard are building and deploying AI agents that are grounded in their company's data and fueled by WRITER's enterprise-grade LLMs. Valued at $1.9B and backed by industry-leading investors including Premji Invest, Radical Ventures, and ICONIQ Growth, 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 and moves fast, and we're looking for smart, hardworking builders and scalers to join us on our journey to create a better future of work with AI.

As an Infrastructure engineer, you'll be at the heart of making this a reality, impacting every enterprise customer who trusts us with their AI-powered workflows. It's about pushing the boundaries of what's possible, proactively identifying and solving complex systemic challenges, and laying the groundwork for our rapid growth and the evolving demands of enterprise generative AI. This is a hybrid position, based out of our New York City or London hubs.

Bring deep focus to one problem at a time, with the breadth to move between SRE, DevOps, Infrastructure, and Platform work over a quarter or two as the leverage shifts. Challenge the status quo and remove toil before adding features β€” 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, not a status quo to be staffed up.

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.

Build the agentic setup as a collective surface: humans and digital teammates working as one team, with shared skills, shared context, and shared on-call workflows. Lead incident response, post-mortems, and root-cause analyses β€” trace failures to the underlying problem (never the symptom), apply the learning back into the architecture, and prevent the same incident from happening twice.

Own the reliability, performance, and efficiency of WRITER's core services end-to-end β€” define and uphold the SLOs and error budgets, carry the on-call pager, and stand behind the outcome metric, not just the system you shipped.

Balance this week's critical work with the 6–12-month platform direction β€” ship the on-call-driving fix today while shaping the multi-year observability, cost, and reliability investments that move WRITER's enterprise customers.

Operate at the seams with product, security, and engineering peers β€” provide expert guidance on system design for reliability, performance, and scalability from conception through launch, connect the infra agenda to product and revenue context, and disagree with evidence, not volume.

  • 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.
  • 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.
  • AI in workflow. AI is part of how you ship, not a thing you've read about β€” 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.
  • Make reversible calls by default β€” 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.
  • Excellent communication, collaboration, and problem-solving skills, with a talent for building strong relationships and connecting with cross-functional teams β€” surface non-goals before anyone asks, and partner with product, security, and platform peers as one delivery surface.
  • A strong sense of ownership and accountability, eager to own mission-critical systems and drive them toward peak performance and unparalleled reliability.
  • Bonus if you have: Software-engineering depth. A software-engineering background, not only config and scripting β€” 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.

Benefits & perks (UK full-time employees):

  • Generous PTO, plus company holidays
  • Comprehensive medical and dental insurance
  • Paid parental leave for all parents (16 weeks)
  • Competitive pension scheme and company contribution
  • Wellness stipend for gym, massage/chiropractor, personal training, etc.
  • Competitive compensation and company stock options

✨Brush Up on Your Technical Skills

For an IT consulting role, be ready to demonstrate your technical prowess. You might face questions on systems integration, cloud technologies, or even troubleshooting specific software. If you have experience with tools like AWS, Azure, or even specific programming languages, make sure you can talk about them fluently.

✨Showcase Your Problem-Solving Approach

IT consulting is all about solving problems for clients. Think about how you can illustrate your approach to a past challenge using the STAR method (Situation, Task, Action, Result). It's a great way to show how you tackle complex issues and come up with effective solutions.

Be prepared with examples that demonstrate your adaptability, communication skills, and how you handle client feedback. Before the interview, think of situations where you worked closely with clients to create effective IT strategies or changes.
