Senior Software Engineer (Backend & Infrastructure)

About the Company Forager is a leading provider of person and organization data, powering enrichment, search, and discovery for B2B platforms worldwide. Our APIs and bulk data feeds deliver billions of data points daily - used by the most widely used go-to-market and sales-intelligence platforms. Our data is refreshed on an industry-leading ~2.5-week cycle: 200M+ verified mobile numbers at a 99% accuracy rate, 850M+ person and company records, and 100M+ intent signals ingested every month. We're a small, remote team, shipping fast with high autonomy and little-to-no bureaucracy. The Role You'll own the backend, data, and infrastructure that deliver Forager's data to platform customers at scale - from ingestion all the way through to the APIs and feeds customers integrate against. This is a backend-first role: most of your time is spent building API features, operating our search and ETL data infrastructure, and owning the DevOps and platform layer underneath it. You'll also contribute to our customer-facing React/TypeScript web app, but that's the minority of the work. This is a senior, high-ownership role on a small team. You won't just contribute features - you'll be responsible for the design, reliability, and evolution of the platform itself. You'll have direct input into product direction and the freedom (and responsibility) to ship work that materially moves our coverage, accuracy, latency, and uptime metrics. You'll grow into full ownership of the platform over time, taking areas over from our CTO as you ramp up - you won't be thrown in the deep end on day one. What You'll Own Ranked by where your time goes: Backend & API development - real-time enrichment APIs (person/org lookup, contact data, reverse search), search and filter endpoints, waterfall enrichment logic, and the credit/billing surfaces customers meter against. Match rate, latency, and freshness directly drive customer value. Design, build, and operate RESTful APIs and scalable backend services - workers, task queues, waterfall lookups, data pipelines - that keep refresh cycles predictable and fill rates high. Build the metering, credit-logging, and billing logic customers rely on for accurate consumption, and help shape which features have the highest impact. Data engineering, ETL & search infrastructure - own the Elasticsearch/ECK stack end-to-end: index and mapping design, ingestion, relevance tuning, cluster health, scaling, and migrations. Design and operate the ETL applications that move billions of data points daily into searchable stores, Snowflake data products, and warehouse exports (S3) while holding fill rates and accuracy. Optimize PostgreSQL (query performance, indexing, caching) and drive measurable improvements in latency, uptime, error rate, fill rate, and scalability. DevOps & platform (core owner) - own day-to-day AWS infrastructure (ECS, S3), infrastructure-as-code, and CI/CD. This is not shared-on-the-side ops: you're responsible for…
