Senior/Staff/PrincipalSoftwareDeveloper

SENIOR/STAFF/PRINCIPAL SOFTWARE DEVELOPER Calgary, AB — Full-time   THE ROLE Financial software runs underneath the biggest decisions people make. When it's good, it saves real money over years. When it's not, those losses compound just as quietly. Most of it was built to capture value, not create it. Neo is building the alternative. Neo has been Canada's fastest-growing company three years running. The platform behind that growth is built entirely in-house: 150 services in production, hundreds of pull requests merged every week, tens of millions of transactions processed every month. The engineers here own their services from architecture decisions through to production. There's no QA team to hand work off to, no DevOps team to manage your deploys. You work on what matters. The priorities are real and the autonomy to execute is yours. This role is for an experienced developer who has shipped real systems at scale, has strong opinions about how to build them, and is ready to be accountable for what goes live. Our stack is GraphQL, Mongo, Node.js, TypeScript, React, and React Native on AWS. If you've spent time at a company where good ideas died in committee and you know you could be going faster, this is the environment those engineers tend to thrive in. WHAT YOU'LL BE DOING - Build and own services and clients end to end: API and schema design, production delivery, long-term technical health. - Serve as code owner for one or more repos, setting the standard for quality and architecture in your area. - Write thorough automated tests as a core part of how you build, not as a follow-up step. - Conduct code reviews that genuinely improve the work: alternative approaches, edge cases, performance, security. - Own your services in production: build observability in from the start: alerting thresholds, dashboards, tracing, logging. - Anticipate downstream risks to reliability, scalability, and security; raise them and advocate for the work to get on the roadmap. - Go beyon
