Systems Engineer
Telavox
Join Telavox as a Systems Engineer for Developer Platform ️
Are you a hands-on systems engineer who thrives in operational depth and wants to own the infrastructure that the rest of engineering runs on? At Telavox, we run our own: on-prem Kubernetes, our own Ceph clusters, and a fleet of physical servers across six countries. We're providers of infrastructure, not consumers of cloud.
If your background is mostly cloud, that's not a problem — the operational instincts transfer, and we'll teach you the on-prem specifics. We care about depth and judgment, not which platform you learned them on.
Telavox is a fast-growing digital telco combining the reliability of telecom with the agility of SaaS. On-prem is a deliberate choice; it's what our product and economics demand, and we're investing in operating it well. As the platform grows in usage and footprint, we need someone who can carry real day-to-day operational ownership while helping us level up how we work.
About the job
This role spans the operational and the architectural in roughly equal measure. Some days you're deep in a cluster issue or pushing an upgrade; other days you're designing how things should work at scale and building the processes that make the team more effective. We don't expect you to master every corner of the stack from day one — bring real depth in one or two areas, and the team covers the rest.
Your day-to-day work includes:
Keeping clusters healthy, responding to issues, and helping with capacity and upgrades across compute and storage.
Designing how things work over time, upgrade procedures across regions, runbooks for recurring operations, and automation for what's currently manual.
Carrying that out in practice. Automation is the direction, but some manual work always remains; you're comfortable at both ends.
Contributing to architecture and tooling decisions where you're strong, and learning from teammates where you're not.
The three areas you'd work across:
Kubernetes on-prem runs most of our application workloads. Cluster lifecycle management — upgrades, capacity, version drift across regions — is a real area we want to invest in.
Ceph (block and S3) is gaining traction across regions, with Sweden having the largest footprint. The challenge is getting the operational foundations right — stability, security, predictable scaling — solved at 1x, not 10x.
Server and OS fleet management spans six countries; most sites are small, Sweden the largest. We use Ansible-driven configuration and keep tightening the lifecycle: upgrade procedures, patching cadence, and drift control.
We're not hiring someone to do all three. If you can drive progress in one or two, the team fills the gap, so strength in just one of these today still makes you who we're looking for.
How we work together
You’d join Infrastructure Engineering, a 15-person team split between Network and Developer Platform. This role is on the Developer Platform team and reports to one of our engineering managers.
This is a hybrid role based at our Malmö HQ, Gjuteriet. We manage our sites in other countries remotely.
English is our working language; Swedish is a small bonus, not a requirement — international candidates are very welcome.
No mandatory on-call. There's a shared org-wide on-call line, and Compute and Storage keep an informal secondary list — maybe 1–3 times a month per domain.
We use Claude Code across engineering, including infrastructure, and you'd help figure out where it's safely and usefully applied to platform work.
About you
You're an autonomous engineer who sees automation as the direction, even when today's task is manual — repetition is a trigger to automate, and you factor in risk from the start rather than discovering it at the end. You're also pragmatic enough to do the manual work while automation catches up, because some of it always remains.
We're looking for someone with:
Strong Linux fundamentals — the substrate everything else sits on.
Operational depth in at least one of: on-prem Kubernetes operations, Ceph (or comparable distributed storage), or server/OS fleet lifecycle management.
Comfort owning work autonomously — taking an unclear problem, scoping it, and seeing it through.
Strongly valued:
A second area from the list above
Ansible or comparable configuration management
A track record of operating systems at scale across distributed sites
Sub-OS work (firmware, BIOS, BMC/IPMI) is a nice addition — we do some ourselves.
This is a mid-to-senior role, with a path toward Senior and eventually Domain Owner in Compute or Storage as you build context. Earlier in your operational career, but strong on the fundamentals and hungry to own real ground? We'd still like to hear from you.
