• 🔧 Hands-on autonomy – You’ll own projects end-to-end and help shape system architecture from the ground up.
• 🧠 Smart, no-fluff culture – Work with a team that values clarity, extreme ownership, and fast iteration.
• 💡 Mission-driven – Build tools that help community banks compete in a world of megafintech.

If you like building durable, production-grade systems that solve real problems—and doing it alongside talented engineers who care deeply about their craft—this is the place.

Role context
:
This is a hands-on, senior individual contributor role on a small, high-throughput platform team. You will own and operate real production systems. You will ship to production early. You will be on-call for the systems you touch. You will be expected to design your part well — and live with the consequences. This role is not about exploration, endless design, or theoretical elegance.

It is about turning ambiguity into working systems under pressure.

• Own one or more production agent workflows or platform components end-to-end.
• Build and operate event-driven systems processing thousands of records per job and millions of events per day.
• Design for failure retries, DLQs, isolation boundaries, alarms, and recovery paths.
• Add telemetry and dashboards to understand job state, throughput, and failure modes.
• Ship changes safely using CI/CD checks and deployment guardrails.
• Participate in on-call rotation and incident response.
• Debug production issues with incomplete information and time pressure.
• Make tradeoffs explicit and ship decision artifacts (code, docs, fixes).
• Improve code quality, tests, and operational clarity in areas you own.
• Work closely with the CEO, COO, and senior engineer on real system constraints.

• Strong Ruby fundamentals as a design tool (encapsulation, boundaries, responsibility), not just syntax.
• Hands-on experience shipping and operating production systems you personally supported.
• Real-world AWS experience, especially Lambda, SQS, Event Bridge, S3, Cloud Watch.
• Firsthand experience with Lambda limits and failure modes; retries, DLQs, timeouts, and back pressure; cost, blast radius, and operational tradeoffs.
• Comfort making decisions with incomplete data and shipping anyway.
• Willingness to be on-call and accountable for outcomes.
• Clear communicator who externalizes thinking and closes loops.

• Only academic, tutorial, or toy-project experience.
• No on-call or incident ownership.
• I was part of the team without first-person responsibility.
• Service-name listing without discussion of outcomes or tradeoffs.
• Preference for extended exploration over shipping.
• Avoidance of pressure, accountability, or ownership.

• Experience in fintech, banking, or regulated environments.
• Exposure to automation, orchestration, or workflow engines.
• Experience operating multi-tenant systems at scale.
• Familiarity with CI/CD pipelines and deployment safety mechanisms.
