Our founders and team have had significant involvement in creating and maintaining projects such as CPython, NumPy, SciPy, Jupyter, Conda, Numba, and others. Our team of open-source maintainers, developers, and designers contributes to over 35 projects fundamental to scientific computing and data science.

Our mission is to make open-source software accessible, sustainable, and community-driven. We work with enterprise customers across industries to help them build effectively on open source, while ensuring their involvement strengthens the communities and projects they depend on. At Quansight, commercial success and community health go hand in hand.

We lead with transparency and accountability, work in the open, and trust each other to own outcomes. We actively seek diverse perspectives and start every collaboration by listening first.

🎯 The Role

Quansight is looking for a full-time remote Senior Infrastructure Engineer to join our team of open-source experts and software engineering professionals. This is a high-ownership, high-autonomy role where you will apply core infrastructure engineering principles such as scalability, observability, reliability, and automation across both internal systems and client engagements.

You will own Quansight's internal cloud infrastructure while serving as the technical lead on client-facing infrastructure engagements, helping clients design, implement, and maintain reliable, scalable solutions. You will also be expected to transfer knowledge to client teams so they can own what you build. This role suits someone comfortable moving between internal operations and external delivery, building systems that outlast their own involvement.

Active participation in open-source communities, as a maintainer or contributor, is a core part of this position. In line with our commitment and approach to open source, the successful candidate will be allocated between 40 and 50 per cent of their structural time to continue contributing to and maintaining existing open-source infrastructure projects.

✅ Key Responsibilities

• Own and evolve Quansight's cloud infrastructure across AWS, Azure, and GCP, ensuring reliable day-to-day operation.
• Build, deploy, and maintain internal dashboards and reporting for operations and project management, including documentation of the systems architecture.
• Lead infrastructure engagements for clients from scoping and architecture through delivery, upskilling client teams on the practices and tooling they need to maintain what you build.
• Contribute to open-source projects and participate in upstream communities.
• Mentor teammates on infrastructure practices and contribute to Quansight's technical presence in the wider community (talks, RFCs, upstream reviews).

📌 Required Qualifications

• 5+ years of experience in infrastructure, DevOps, or platform engineering.
• Open-source experience as a maintainer or sustained contributor; this role comes with structural time allocated to open-source maintenance.
• Ability to independently scope, architect, and execute infrastructure projects end-to-end, while knowing when to seek feedback and input.
• Production experience across at least two of AWS, Azure, and GCP, with working familiarity across all three.
• Strong proficiency with infrastructure-as-code tools such as Terraform, Pulumi, or CloudFormation, and experience managing containerized workloads on Kubernetes, including Helm chart development.
• Experience building and maintaining CI/CD pipelines (GitHub Actions, GitLab CI/CD, CircleCI, or equivalent).
• Hands-on experience with observability tooling such as Prometheus, Grafana, and/or the ELK/OpenSearch stack, and familiarity with cloud security best practices, including secrets management, IAM/RBAC, and pipeline security scanning.
• Proficiency in Python or another general-purpose language for scripting and automation.
• Client-facing experience: translating requirements into infrastructure designs, communicating technical decisions to non-technical stakeholders, and managing expectations.
• Fluency with Git and GitHub for version control, code review, and asynchronous collaboration across a distributed remote team.
• Ability to constructively receive and act on feedback.

⭐ Desirable Experience

• Experience with GitOps workflows and tools such as ArgoCD or Flux.
• Experience with data science workflows, platforms, data management practices and MLOps.
• Experience with configuration management tools such as Ansible.
• Experience with SQL and database management.
• Familiarity with the PyData ecosystem.
• Experience deploying AI/ML workloads in production - GPU orchestration on Kubernetes, model-serving frameworks (KServe, Ray Serve, vLLM, Triton), or LLM inference infrastructure.

🎁 Benefits

You'll become essential to a small, collaborative, fully distributed accessibility and engineering team. We strive to provide a working environment that gives you room to learn and grow.

Quansight draws from experience in many large open-source communities over the years. Because these communities operate remotely and strive to be as inclusive and participatory as possible, they must also strive to be more transparent and systematic in communicating, sharing information, and working. We are building a culture at Quansight that follows and builds upon these principles.

We offer flexibility in work times and locations, and vacation time is not just encouraged but celebrated and enforced.

We offer competitive compensation, a comprehensive sick policy and parental leave, and a generous amount of flexible paid time off. If you are located in the United States, Canada, Germany or the UK we also offer a comprehensive benefits package.

🛂 Visa & Eligibility

We are an equal opportunity employer. All qualified applicants will receive equal consideration regardless of race, religion, gender identity, national origin, disability, sexual orientation, age, veteran status, or any other basis protected by applicable law.
