Clients.ai builds AI agents that bring you clients—traffic, funnels, follow-up—done. The product’s real, the demand is real, and we’re shipping fast. If you like owning problems end-to-end and keeping systems calm under load, you’ll like it here.

The work (all backend, zero frontend)

Kill the bug backlog. Stabilize services so our agents keep working while people sleep.

Own the plumbing: queues, schedulers, worker jobs, and webhooks that power Traffic, Conversion, and Nurture agents.

clients.ai

Trace and fix hard issues across services and infra; add the logs, metrics, and flags so they don’t come back.

Keep third-party integrations boring: Stripe, SendGrid, Unipile, etc.—idempotent, retried, and observable.

Raise the floor: tests where it matters, clean CI, and clear SLOs (latency, error rate).

Languages & stack

Frontend: JavaScript with JSX for React components.

Backend: TypeScript with strict types and a real compilation pipeline.

Ecosystem: Modern JavaScript/Node.js on both sides with extensive npm deps.

Core backend: TypeScript, NestJS microservices, Prisma, PostgreSQL, Redis (queues/caching).

Infra/DevOps: Azure Kubernetes Service, GitHub Actions, structured logging/tracing, feature flags/canaries.

Must-haves

5+ years building production SaaS in TS/Node and shipping under pressure.

You’re a calm debugger: logs, traces, SQL plans, heap snapshots—you live in dashboards.

Claude Code power-user (or Cursor). We cover the high-usage plan; you bring mastery and taste.

Comfortable with queues, concurrency, back-pressure, idempotency, and migrations without downtime.

Disciplined CI/CD: you ship fast and leave the place tidier than you found it.

Nice-to-haves

Social media automation experience (posting pipelines, inbox sync, rate-limit aware scheduling, auth flows).

Security/compliance hardening (secrets, tenant isolation, audit trails).

Cost/perf tuning at scale (indexes, pooling, cache hit-rates).

How we work

Fast-paced startup, short loops, real ownership.

Remote with ET overlap.

“Definition of Done” = ticket closed, tests green, dashboards quiet.

Compensation

$5,000 USD/month (full-time contractor to start).

Upside as we scale (performance-based increases; equity talks after sustained impact).

If you can ship stable, elegant software at warp speed, our agents will do the selling—you make the machine unbreakable.
