What You’ll Do
We’re looking for a Fullstack Engineer (Backend-leaning) to build and scale the core systems behind Airtop’s AI-powered automation platform. You’ll work across the stack with a strong emphasis on backend, distributed systems, and infrastructure. You’ll collaborate closely with product and AI engineers to ship reliable, high-performance features that power agentic workflows and real-time web automation.
You’ll be responsible for:
Designing and building backend services and APIs that power AI-driven features and web automation at scale
Owning distributed systems that handle real-time orchestration, scheduling, and stateful agent flows
Implementing robust data pipelines and storage patterns for logs, traces, evals, and long-running tasks
Standing up reliable infra: containerization, observability, CI/CD, and cost-aware cloud architecture
Building user-facing features end to end when needed, from database to UI
Driving performance, reliability, and security across the platform
Tech Stack & Tools
Services and infra: Kubernetes or container orchestration, Pulumi, modern cloud (GCP, AWS), queues and streaming (Kafka, Pub/Sub, SQS), Redis
Languages: Typescript, Go, Python
Datastores: Postgres, Redis, DynamoDB
AI platform: Multi-model orchestration (OpenAI, Anthropic, Gemini, OSS models), LangChain or LangGraph, evals and observability (Brainstrust, Langsmith)
Web automation: Cloud browsers and real-time browser control
Who You Are
5+ years building production backend systems and APIs that scale
Deep experience with distributed systems fundamentals: concurrency, queues, idempotency, retries, horizontal scaling, etc.
Strong with cloud infra and reliability engineering: containerization, networking, monitoring, alerting, incident response
Comfortable across the stack. You can build or iterate on frontend features when needed
Fluent in Typescript and comfortable in Go and/or Python
Pragmatic engineer who ships, measures, and iterates quickly. We’re a startup; we ship fast.
Nice to Have
Experience running real-time systems or automation at scale
Hands-on with LLMs, agentic systems, or tool orchestration
Background in web automation, scraping, or browser control
Experience with eval-driven development and experiment tracking
