Waystone Software is building the future of CRM, marketing, and practice management automation for financial advisors.

Our products, Altitude (www.gainaltitude.ai) and Pathfinder, are built to simplify complex client management, drive growth, and make every process smarter through automation and AI.

We’re looking for a Senior Backend & Platform Engineer who is fast, sharp, and can cook. This is a critical, hands-on role where you’ll work directly on our core infrastructure, integrations, and performance as we scale. You’ll be joining a small, senior team shipping weekly, tackling real problems, and building tools our users rely on every day. If you’re hungry to lead by doing—and want your work to matter—you’ll thrive here.

Altitude and Pathfinder stack: Node/TypeScript, PostgreSQL/Prisma, AWS, React/Next.js on the front end.

This offer is exclusive to getonbrd.com.

Where you come in

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 with measurable impact.
  • 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.
  • Grow: take on broader ownership of reliability and integrations and grow with us.

You must come with (non-negotiable)

  • English fluency (C1/C2) — quick, clear spoken and written communication; we do live technical discussions daily.
  • 7+ years backend with Node.js/TypeScript.
  • PostgreSQL expertise in production: indexes, transactions/locking, safe migrations, constraints for data integrity.
  • Prisma experience and judgment to use raw SQL when it’s the right tool.
  • AWS hands-on: RDS tuning/monitoring, CloudWatch alarms, ElastiCache/Redis, SQS/SNS workers.
  • Integrations at scale: OAuth2 auth flows, webhook ingestion with signature validation, idempotency keys, retries/backoff, rate limits.
  • Observability that drives action: tracing/metrics/logs, define SLOs and keep them green.
  • Bias to ship: comfortable fixing gnarly bugs today and designing the durable solution tomorrow.
  • Work ethic: willing to flex hours for production fixes and critical cutovers.

Nice to Haves

Experience working with AI in SaaS applications (LLM integrations, embeddings, vector search).
Advanced data patterns — Outbox/CQRS, event sourcing, read replicas, partitioning, or stream processing.
Performance engineering — load testing, chaos testing, and CI/CD gates for latency and query budgets.
Fintech/CRM background with awareness of compliance-sensitive environments.
React/Next.js familiarity for smooth API contracts and end-to-end collaboration.
Agile leadership experience — mentoring, sprint execution, breaking down epics.
Multi-tenant SaaS mastery — tenancy boundaries, data isolation, advanced caching strategies.
Incident response readiness — on-call, runbooks, distributed tracing/observability tools.
Domain-driven design — mapping advisor workflows into clean, modular schemas.
Security & compliance mindset — SOC 2, data privacy, and secure coding in regulated SaaS.

Conditions

Ownership over what you build — you design it, ship it, measure it.
Small, senior team — no bureaucracy, just experienced people solving hard problems with speed and quality.
Modern tech stack — Node/TypeScript, Postgres/Prisma, AWS, React/Next.js — minimal technical debt.
Startup speed — we move fast, iterate daily, and ship enhancements weekly.
Direct access to product — your work impacts real users immediately.
Pragmatic engineering — Prisma for most flows; raw SQL when performance demands it.
Lightweight process — short design notes, schema diagrams, runbooks; just enough to align without slowing down.
Culture of ownership — when you pick up a problem, you carry it through: design → fix → deploy → measure.
Obsessed with users — advisors love our platform and are vocal; what you build matters the moment it’s in production.
Flexible remote work — full autonomy with LATAM-preferred timezone overlap.
