Sixtyfour is a data orchestration engine for company and people data. Our AI agents specialize in enriching detailed datapoints about individuals and organizations, gathering information from both public and proprietary sources. We enable enterprise customers to build custom data pipelines that help them find, enrich, qualify, and act on company-specific requirements for people and business data.
Our Mission
To power how enterprises understand and act on people and companies with world-class intelligence.
What you’ll do
Build polished, fast product experiences in Next.js + TypeScript (design-quality UI, accessible components, responsive layouts).
Design clean backend contracts and APIs (FastAPI/Python) for workflows, jobs, billing, and auth.
Evolve our workflow engine (DAG/state machine): scheduling, retries/idempotency, rate limits, progress tracking, logs, and user-visible run history.
Ship data pipelines and background workers (Celery/queues), with strong observability and alerting.
Deploy the stack on AWS + Docker (ECS/EKS or similar), with caching (Redis), pagination, backpressure, and cost controls.
Implement product features end-to-end: DB schema → API → UI, including tests and telemetry.
Maintain a high bar for reliability, performance, and UX; instrument everything.
Be very customer-focused on how certain product decisions impact end customers.
Minimum requirements
Strong backend skills in Python (FastAPI preferred): API design, testing, error handling, schema/versioning.
Good design taste is a must.
Experience deploying/operating with Docker and a major cloud (AWS preferred: ECS/EKS/Lambda, SQS, CloudWatch).
Comfortable with Postgres (or MySQL) schema design and Redis (caching, rate limiting, locks).
Sixtyfour deploys AI agents that investigate people and companies across the open and dark web, official records, proprietary databases, and unstructured sources. We resolve identities, map entity relationships, and surface risk signals for teams where data quality is essential.
