Founding Software Engineer, Data Infrastructure

role.

This range is provided by Airweave (YC X25). Your actual pay will be based on your skills and experience — talk with your recruiter to learn more.

Base Pay Range We're looking for a founding engineer to own Airweave's data and infrastructure layer, the systems that make our distributed search and data pipelines scalable, reliable and observable.

At Airweave, you'll build and operate the platform that thousands of AI agents depend on. That means distributed sync pipelines pulling data from dozens of sources, vector databases powering LLM search, and the orchestration layer that keeps it all running. You'll work closely with the product team, but your focus is on the foundation: making sure data flows reliably at scale, LLM inference stays fast, and the whole system holds up under real production load.

This is early‑stage infrastructure work. The architecture is still being shaped, and your decisions will define how we scale.

What You'll Work On

Design and scale distributed data pipelines that sync hundreds of millions of documents from dozens of sources into advanced search indexes

Build and improve Temporal workflows for parallel sync orchestration: retries, backpressure, and failure recovery across workers

Own our Kubernetes deployments with Helm charts: autoscaling, and resource management for bursty search, sync and LLM workloads

Scale PostgreSQL for high‑throughput; connection pooling, read replicas, partitioning (we ask a lot from this database)

Manage vector database (Vespa) infrastructure: sharding, replication, backup strategies for large‑scale agentic search

Orchestrate and optimize LLM inference pipelines: batching, caching, provider failover

Build monitoring and alerting with Prometheus, Grafana, and custom instrumentation for cluster health

Infrastructure as code for the base with Terraform

You Might Be a Fit If

You've built or operated data pipelines at scale: ETL, event processing, streaming, or sync infrastructure

You're comfortable with Kubernetes, Terraform, and infrastructure as code

You've scaled databases and understand the tradeoffs (pooling, replication, sharding)

You have experience with distributed systems: workflow orchestration, message queues, eventual consistency

You're interested in LLM infrastructure: embeddings, vector search, inference optimization

You like building reliable systems and have opinions about observability

You're drawn to early‑stage environments where you own the whole problem

Bonus Points

Experience with Temporal, Airflow, or similar workflow engines

Background in scaling search (Elastic, Qdrant, Pinecone, Weaviate)

Familiarity with LLM inference
