Build and operate infrastructure that powers open source software at scale. You will work directly with client engineering teams to design, deploy and maintain production platforms. Kubernetes is central to how we work and a tool we are investing in heavily, but the role spans the broader infrastructure landscape.
This isn't passive infrastructure management. You will be solving real operational problems, recommending open source solutions that genuinely fit the problem and helping clients build platforms they can own and maintain long term.
This role combines deep technical work with collaborative consulting. You will partner with client engineering teams to solve their toughest infrastructure challenges, develop genuine platform expertise and grow into technical leadership over time.
Location: Fully remote (preference for EU or East Coast US hours)
Travel: Optional conference attendance
What You'll Actually Do
Platform Engineering: Design, deploy and maintain production infrastructure for client workloads: Kubernetes is a key part of our toolkit and you will use it regularly, but you will also work across the broader platform stack including networking, storage, observability and CI/CD
Reliability Engineering: Own the operational health of client platforms: you are comfortable with incident response, post-mortems and building systems that fail gracefully
Open Source Solutions: Favour open source tooling that is well-maintained and community-aligned. You do not need to be an active upstream contributor, but you should understand the ecosystems you are working in and be able to evaluate tools critically
Infrastructure as Code: Treat infrastructure configuration as software: version controlled, reviewed and repeatable. This is a mindset as much as a skill set and it shapes how you approach every engagement
Client Partnership: Translate client operational needs into technical solutions. You will help clients understand the trade-offs between convenience and long-term maintainability
Navigate Constraints: Balance technical excellence with real-world pressures: customer deadlines, legacy infrastructure, budget limitations, all while keeping quality high
Be a Technical Advisor: Explain complex infrastructure decisions to product and engineering teams, provide honest timelines and build trust through transparent communication
Grow the Practice: As you develop in the role, you will take on more responsibility for shaping how Collabora delivers infrastructure consultancy - mentoring colleagues and leading client engagements
What We're Looking For
Solid Kubernetes experience. You are comfortable operating clusters in production, troubleshooting workload failures, managing networking and storage and navigating unfamiliar configurations independently. You do not need to have seen everything, but you should know how to find your way
Broader infrastructure competence. Kubernetes is not the whole job. You are comfortable working across the platform stack: networking, storage, Linux systems, CI/CD pipelines and observability tooling
Infrastructure as Code mindset. You treat infrastructure configuration as software: version controlled, peer reviewed and repeatable. You are uncomfortable with manual changes to production systems and you can articulate why. Experience with Ansible, Terraform or equivalent tooling is expected
SRE or customer-facing support background. You are comfortable diagnosing and resolving issues reported by clients, often from vague descriptions and limited reproduction steps. You understand that good incident response is as much about communication as it is about technical skill
Consultancy or client-facing technical background. You know how to balance technical excellence with business constraints, manage expectations across multiple projects and advocate for the right solution while respecting customer timelines
Strong English communication skills, both spoken and written, for documentation, incident reports and client discussions
Self-directed work style. You thrive in a remote, asynchronous environment and take ownership of your work without needing close supervision
Nice to HaveHelm familiarity is useful. We use it regularly on client engagements and you will pick it up quickly if you have not worked with it deeply yet
Cloud provider experience: AWS, GCP or Azure experience informs good infrastructure decisions; understanding the primitives matters
CI/CD pipeline experience: GitLab CI, GitHub Actions or equivalent
Observability tooling: Prometheus, Grafana, Loki, OpenTelemetry or similar
Security and compliance awareness: network policy, RBAC, pod security standards or supply chain security tooling
Scripting and automation: Python, Bash or Go for operational tooling
Rust: increasingly relevant for infrastructure utilities and systems-level tooling; not a primary requirement but a genuine advantage
Open source contribution history. We know not every employer makes this easy. Active community participation at any level is valued and we will support you in building that profile as part of the role

We offer a competitive benefits package tailored to each country in which we have employees, plus a core global benefit offering accessible to all Collaborans. Our core benefits include:
A Typical Day
Review overnight alerts for a client platform, triage and resolve or escalate
Pair with a colleague on a tricky networking issue in a client's cluster
Write up findings from yesterday's incident as a post-mortem draft
Deep work: build out Terraform modules for a new client environment
Quick video call with a client team to walk through your proposed architecture and answer questions
Review a colleague's Helm chart changes before they are applied to staging
Respond to a client query about a deployment failure, diagnose from logs and explain the fix clearly
Update a client on progress, discuss the trade-offs between a fast workaround and a properly engineered solution
Join team meeting to discuss tooling decisions
Write documentation that explains not just what was configured but why
No two days are identical but here is a realistic picture of what this role looks like in practice.
Morning
Midday
Afternoon
Some days are deep technical work, others involve more client communication. You will balance both based on project needs and your strengths.
Our Interview Process
Application Review (within 1 week) — we look at your experience, any public work and your screening question responses

Technical Interview (2–3 hours)
Technical Deep-Dive — discuss infrastructure architecture, past incidents you have owned and how you approach problem-solving. No whiteboard exercises
Infrastructure Review Session — review a real infrastructure configuration or scenario together and discuss the trade-offs
Client Scenario Discussion — talk through a realistic customer situation involving technical debt, timeline pressure and competing priorities. We want to see your thought process, not a right answer
Head of Open Source Software Consulting team Discussion (60 min) — ask about day-to-day work and how Collabora operates, discuss compensation and benefits
Offer (within 1 week of final interview)

Even if we do not move forward, we will tell you why
We respect your time and provide a clear, structured process.
Total timeline: 3–4 weeks from application to offer
What Happens Next
Collabora's Commitment
We are committed to building a diverse team and inclusive environment. We encourage applications from people under-represented in tech.
We evaluate candidates based on skills and contributions, not pedigree. If you are unsure whether you qualify, apply anyway. Imposter syndrome is real and you might be exactly who we are looking for.
We recognise that the combination of deep infrastructure expertise and consulting skills is rare. If you have strong Kubernetes and platform experience and are newer to the consulting side of the role, or vice versa — we want to hear from you. We can develop one if the other is solid.
