Senior Full Stack Developer, R&D;

We are looking for a Senior Full Stack Developer who can bridge exploratory research and production-grade delivery. The ideal candidate is a full stack developer, with strong product instincts and who can take an idea from prototype to shipped feature without losing rigor or velocity. We are looking for someone who thrives in ambiguous problem spaces, writes code that others are proud to maintain, and brings a genuine curiosity about applied AI to everything built.

Design, develop, and ship full stack features across our Node.js/TypeScript backend and React frontend, from initial scoping through deployment and monitoring.

Translate R&D; prototypes and research findings into production-ready, maintainable code that meets Estateably’s quality and reliability standards.

Actively participate in Scrum ceremonies: planning, stand‑ups, reviews, and retrospectives, to stay aligned with product and engineering teams.

Build and integrate AI‑powered capabilities (e.g. document processing, intelligent automation, multi‑agent workflows) using modern LLM tooling and patterns.

Investigate and resolve production issues promptly, applying well‑tested, robust solutions that protect customer trust and service continuity.

Partner closely with QA, product, and design to deliver a cohesive, high‑quality user experience, including thoughtful use of our design system.

Contribute architectural thinking on recent features, evaluating trade‑offs across scalability, maintainability, performance, and long‑term system health.

Support the growth of peers through code review, technical mentorship, and knowledge sharing across the team.

5+ years of full stack engineering experience, with a track record of shipping production systems.

- API design, data modelling, frontend components; Experience collaborating on cross‑functional teams alongside product, design,



and QA in an agile environment.
- Strong written and verbal communication skills, with the ability to articulate technical decisions to both engineering and non‑engineering stakeholders.
- Advanced English proficiency (written and verbal) to effectively collaborate with team members across Canada and the United States.
