Senior Software Engineer, AI Data Systems & Database Infrastructure

Build a safer world with us, one incident at a time.

Ambient.ai is the category creator and leader in Agentic Physical Security. Powered by Ambient Pulsar, our first reasoning Vision‑Language Model purpose‑built for physical security, the platform seamlessly integrates with existing security cameras and access control systems to unify monitoring, access control, threat assessment, response, and investigations through an always‑on reasoning layer that augments operators with superhuman capabilities. The results: 95% fewer false alarms, investigations 20× faster, and 10× faster response.

The momentum speaks for itself: we doubled new ARR in FY26 and have delivered results for world‑class customers including Cisco, Service Now, Sentinel One, Tik Tok, Bayer, and MoMA. We recently ranked #71 out of 500 on the Forbes best‑startup employers list.

Founded in 2017 and backed by Andreessen Horowitz, Y Combinator, and Allegion Ventures, Ambient.ai is on a fast‑paced journey to fulfill our mission: prevent every security incident possible.

We are looking for a Senior Platform Engineer to design, build, and scale the database platform that powers our most critical production and AI systems. The ideal candidate deeply understands databases and distributed systems, and can build the platforms, abstractions, and scaling patterns required to operate data stores reliably at high scale.

In this role, you will work at the intersection of databases, distributed systems, application architecture, and AI infrastructure. You will help scale relational, analytical, and vector data stores across both the database layer and the application layer. This includes designing systems for partitioning, sharding, routing, caching, replication, query optimization, and high‑availability operations.

You will also work closely with AI teams to build the data infrastructure that supports modern AI applications, including vector search, retrieval‑augmented generation, embedding stores, model evaluation datasets, analytical workloads, and low‑latency data access for AI‑powered product experiences.

The ideal candidate has built or operated database platforms at scale and understands the trade‑offs behind systems like Vitess, Cockroach DB, Spanner, DynamoDB, Cassandra, Redis, Click House, and modern vector search systems. You should be comfortable reasoning about latency, availability, durability, consistency, reliability, and operational complexity in Tier‑0 production environments.

This role is ideal for someone who wants to apply deep database and distributed systems expertise to the next generation of AI‑powered products.

• Design, build, and operate scalable database infrastructure for mission‑critical production and AI systems.
• Scale relational, analytical, and vector data stores to support growing product, customer, and AI workloads.
• Improve database performance across latency, throughput, availability, reliability, durability, and cost.
• Own database architecture decisions around partitioning, sharding, replication, indexing, caching, query optimization, and data modeling.
• Operate tier‑0 data services with strong reliability, observability, incident response, and disaster recovery practices.
• Build automation and tooling to improve database provisioning, migrations, monitoring, backups, failover, and capacity planning.
• Partner with AI teams to support data infrastructure needs for embeddings, vector search, retrieval workflows, training data, model evaluation, and analytics.
• Build low‑latency data‑serving patterns that power AI features in production.
• Work closely with engineering teams to design data access patterns that are scalable, reliable, and performant.
• Identify bottlenecks in production systems and drive improvements across application, database, cache, and infrastructure layers.
• Define and enforce best practices for schema design, database usage, data lifecycle management, and operational safety.
• Help evolve our long‑term data platform strategy as the company scales.

• 7+ years of industry experience in database infrastructure, backend infrastructure, distributed systems, or production platform…
