Working at Kelir.
Kelir is a small team building cellular business phone infrastructure for the US market. We're not actively hiring as of mid-2026, but interesting candidates are welcome to introduce themselves — when roles do open, we start by emailing back people we've already heard from.
When we hire, we hire for: telephony engineers (Telnyx, VoLTE, SIP, eSIM provisioning); platform engineers (Node/TypeScript, AWS, PostgreSQL); mobile engineers (Flutter, iOS, Android, eSIM CTCellularPlanProvisioning); product designers who care about systems thinking; and a small number of go-to-market hires focused on small-business sales.
We're remote-friendly within the United States. We pay in cash, we don't dilute early hires, and we pick people based on what they've shipped — not pedigree.
Drop us a line.
Email jobs@kelir.io with a couple sentences about who you are, what you've shipped lately, and what you'd want to work on at Kelir. Real human reads the inbox; we'll respond when there's a fit, and we'll keep your note for when there is.
We don't accept unsolicited résumés or recruiter pitches.
