The role

You will build backend-heavy full stack features that turn the core platform into solutions for specific industries. The work includes industry data models, workflows, automations, integrations with industry systems, and reusable templates.

What you will do

• Lead the technical design and implementation of backend-heavy features that power industry solutions
• Evaluate architectural trade-offs across APIs, data models, integrations, and event-driven systems
• Build scalable APIs and business logic using Node.js/NestJS, with Firestore, PostgreSQL, Elasticsearch, and Redis as data layers
• Use GCP tools like Cloud Tasks, Cloud Scheduler, Pub/Sub, and Cloud Functions to build event-driven infrastructure
• Build integrations with industry systems such as practice management, MLS, dealer management, and POS systems
• Own significant technical initiatives, including a reusable industry layer of configurable models, templates, and automation packs
• Own the full development lifecycle, from API design and data modeling to testing, deployment, and maintenance
• Work closely with core platform and app teams to shape the extension points industry solutions depend on
• Help meet industry requirements such as data privacy, consent, and audit trails
• Mentor engineers through code reviews, design discussions, and technical guidance

Required qualifications

• 5+ years of software engineering experience with a strong focus on backend systems and API design
• Deep expertise in Node.js/NestJS, TypeScript, and distributed systems fundamentals
• Experience with both SQL and NoSQL databases at scale
• Ability to work end-to-end across the stack, owning backend complexity and integrating with UI components
• Solid understanding of async workflows, queues, background jobs, webhooks, and system state transitions
• Experience integrating with third-party APIs, including auth flows, rate limits, data mapping, and sync reliability
• Familiarity with GCP services or willingness to get hands-on with them
• Openness to using AI tools such as Cursor, GitHub Copilot, or Claude Code
• Strong debugging and system design skills, with the ability to make pragmatic architectural decisions
• Curiosity about how different industries work, and comfort learning from non-technical domain experts

Nice to have

• Experience building vertical SaaS or industry-specific products
• Hands-on work with industry standards or systems like HL7/FHIR, RESO/MLS feeds, or payment and POS integrations
• Experience with metadata-driven or configuration-based systems, such as custom objects, workflow engines, or templating
• Experience shipping in regulated environments (HIPAA, SOC 2, GDPR)

Benefits

• Work directly with domain experts and see your features change how businesses in each vertical operate
• Join a small, high-leverage team that values product thinking and pragmatic engineering
