Senior Back-end & Platform Engineer en Waystone Software / Altitude

We’re in a shipping sprint: fixing bugs, delivering enhancements, and shipping features from a passionate backlog of user requests. We need a senior builder who can lead by coding (player-coach), learn our platform quickly, and take ownership of the hardest problems: performance, Pathfinder integrations, data model health, and scaling reliably as usage grows.

This is a role for someone who is hungry and thrives in a startup sprint—someone willing to push hard, including late nights when needed, to make an outsized impact. We’re looking for someone who’s been through this kind of growth before, knows what pitfalls to watch out for, and is hands-on solving problems every day.

What you’ll accomplish in your first 6–12 months

• Absorb the platform fast: learn our schema and flows in weeks, not months; publish a short ERD and the “how we query” guide.
• Stabilize and speed up delivery: cut error rates, reduce “flaky” behavior, and improve latency.
• Triage → fix → ship: own slices of the bug backlog; deliver clean enhancements end-to-end, and occasionally jump into application stories to keep user-facing features moving.
• Help Build Integrations: ship production-grade integrations with OAuth2, webhooks, retries with backoff, idempotency, and rate-limit handling.
• Harden the platform: improve indexing, safe migrations, background processing, caching, and connection management.
• Make the team faster: lend your expertise to help the team level up and create guardrails that prevent regressions without slowing us down.
• Flex into application delivery: when platform demands are stable, pick up user stories on the application side (API contracts, backend logic, integrations) to help the team ship features faster.
• Grow: take on broader ownership of reliability and integrations and grow with us.
