Platform Engineer

As a Senior Platform Engineer at Maven Securities, you work from our Chicago office supporting the desks and trading teams there. You build and operate the environment Maven's applications run on: 22 Kubernetes clusters across Europe, the US and Asia, all on-premises, supporting over 1,100 production deployments for 44 teams and desks. You understand what Chicago teams are trying to accomplish, turn that into something they can run themselves, and handle the production problems that cannot wait for London.

What you'll do

• Sit with Chicago teams to understand what they are trying to accomplish, including the parts they have not spelled out, and turn that into a requirement the platform team can act on
• Design better ways of working for those teams: hosted developer environments (Coder), the path from a change to production, templates and checks that make the safe way the easy one
• Recommend how to apply what you already have, and push back when a request is the wrong solution
• Follow through across the timezone gap so things do not stall when London has gone home
• Be available in US hours when a deployment or application misbehaves, and handle the ones that cannot wait
• Contribute to the shared platform rather than a US-specific fork, maintaining one repository and one set of standards
• Work with the Chicago Linux, network and storage teams on anything that spans the hosts and the cluster

What you bring

• Around six years in a platform, SRE, DevOps or development role
• Comfort working with traders, researchers and developers: you can listen to a messy request, find the actual problem, and explain a proposed approach in their terms
• Ability to recommend a direction and to say no when the ask is unreasonable or would make things worse
• Persistent follow-up across a six-hour timezone gap
• Production Kubernetes experience: you have deployed to it, debugged a broken change, and can deal with an incident without waiting for someone else
• Comfort with GitOps, including ArgoCD, Helm and Kustomize, or equivalent experience with Terraform or similar
• Ability to write code to automate work, primarily in Python or Go
• Experience building a development or deployment process that other teams then ran themselves

Nice to have

• Experience in a trading firm or another environment where the users of the platform are close to the business
• Judgment about when to decide locally and when to wait for the rest of the team
• Experience with Coder, Gitpod, Codespaces, or another hosted developer environment
• Kubernetes on-premises or on bare metal
• Experience operating observability stacks such as Prometheus, Thanos, Grafana, OpenTelemetry or similar
• Experience in a new or growing regional team
• Experience using AI-powered tools to improve efficiency and workflows

What we offer

• Salary of $150,000 to $200,000, plus a discretionary bonus
• A great engineering environment where technology is key to success
• A great, friendly, informal, and highly rewarding culture
• Informal dress code, free food and social events
