Founding Engineer (Full-Time)

Location: Ahmedabad, India (In person Only)

Type: Full-Time, On-Site

Experience: 2–5 years

About Us

Perceptive Labs is building the marketplace of autonomous AI agents. Each agent runs 24/7, connects directly to customer data, and delivers measurable business outcomes (recommendations, automations, workflows). We’re early-stage and looking for a Founding Engineer to join us at inception. This role will own the technical backbone of the company and help shape the culture, standards, and product DNA.

What You’ll Do

• Architect and build the core platform: multi-tenant backend APIs (FastAPI/NestJS), workflows (Temporal), Postgres schemas, Redis event queues.
• Develop & deploy the first AI agents: end-to-end orchestration, tool APIs, and connectors (Postgres/MySQL, Google Sheets, S3/R2, WhatsApp APIs).
• Implement multi-tenant architecture: enforce tenant_id across Postgres/pgvector, per-tenant file storage (R2/S3).
• Set up CI/CD pipelines with GitHub Actions, Vercel (web), Fly.io/Render (API + worker).
• Manage observability: tracing/logging with OpenTelemetry, Langfuse, Sentry, PostHog, Grafana.
• Optimize infra costs: scale-to-zero workers, token usage tracking, Cloudflare R2 storage.
• Collaborate directly with founder + design intern on roadmap, architecture, and product decisions.

Required Skills & Experience

• Strong in Python (FastAPI, Pydantic) and/or TypeScript (NestJS, Node.js).
• Proficient with Postgres (schemas, multi-tenant patterns, pgvector).
• Experience with Redis (Streams, caching, queues).
• Hands-on with Temporal (or Celery/Airflow but must be willing to learn Temporal fast).
• Comfortable with containerization (Docker) and deploying to Fly.io, Render, or AWS/GCP/Azure.
• Knowledge of CI/CD (GitHub Actions), infra-as-code (Terraform basics).
• Exposure to LLM integration (OpenAI APIs, LangChain, or direct API calls).
• Strong debugging skills across full stack (frontend → backend → DB → infra).

Nice to Have

• Prior work with Langfuse (prompt/version tracking) or OpenTelemetry.
• Experience with S3/R2 storage and CDN integration.
• Understanding of multi-tenant security (scoped API keys, audit logs).
• Startup/early-stage experience, shipping 0→1 products.

Interview Process

1. Initial Conversation (30 minutes, online): Introduction to Perceptive Labs, career aspirations, and behavioural assessment.
