Senior Software Engineer, Reliability

5+ years building and operating production backend or distributed systems where downtime is something real people notice

Real depth in AWS and infrastructure as code (we use Terraform), and a bias toward reproducibility

You’ve owned reliability as a discipline, not a fire drill — SLOs, meaningful alerting, load testing, and incident review that changes what gets built next

Comfortable in real-time and telephony systems, or genuinely eager to get there; SIP, RTP, and media behavior are the substrate here

Fluency using AI as a multiplier across diagnosis, analysis, and testing

Hands-on and scrappy; you’d rather run the load test or read the SIP trace yourself than wait on someone else

A clear communicator who writes things down

A collaborative, low-ego approach — everyone here sweeps the floor

Bonus: production FreeSWITCH, Kamailio, or carrier SIP trunking; load-testing a system through a seasonal peak; Postgres at scale; operating a consumer hardware fleet; or observability tooling like Grafana

We’re building tech that protects childhood: We’re on a quest to give kids a more analog childhood — one with real conversations, real connection, and way less screen time. No doomscrolling, data mining, or dopamine traps — just a simpler, better way for kids to stay in touch. This is a rare opportunity to build something that truly matters.

You’ll own the promise the whole company is judged on: Reliability is our top priority this year, and this is the engineering role that owns it. You’ll set the technical direction for how a Tin Can stays dependable as we scale.

Small, high-trust team: Every company says “team,” but at Tin Can it means something different. We’re a small, mission-driven group that genuinely has each other’s backs — professionally and personally. You’ll be joining a tight-knit crew where your ideas and instincts matter from day one.

Room to explore, not just execute: You’ll have the space to explore new ideas, challenge assumptions, and build systems that reflect our values of trust, simplicity, and care.

If you’re excited by the idea of making a kid’s phone call something their family never has to think about, we’d love to meet you.
