The posting
We’re building Rumor, a data-rich, AI-enhanced platform powering culture’s most important events. Our focus now is on real-time intelligence: profile enrichment, discovery, recommendations, and network graph. We’re looking for a Senior Founding Engineer to design and own the backend systems that make this possible.
What You’ll Lead
- Core backend architecture: evolve our microservices, data models, API layer, and system reliability.
- Data & intelligence layer: build enrichment pipelines, scoring engines, and recommendation logic.
- Cross-product execution: ship features across Host Portal, Member App, and Admin tools in tight partnership with product + design.
- Technical decisions: set patterns, improve tooling, drive performance, and shape the engineering culture.
What You Bring
- 6–10+ years engineering experience, ideally across startups and system design.
- Strength in backend architecture, distributed systems, and microservices.
- Experience with Node.js/NestJS, TypeScript, Postgres, Redis, AWS, queues, and event-driven architectures.
- Strong grasp of data modeling, search, rankings, and real-time systems.
- Ability to move fast without breaking quality — pragmatic, not academic.
- Comfortable owning large scopes and collaborating closely with product/design.
Engagement Structure
- Contract with the intention to convert to full-time
- NYC preferred (hybrid)
- High ownership, high impact, high visibility role
