Software Engineer, Infra/Data
Sazabi
What we're building
In 2026, we're on the verge of an "infinite software crisis." How will we support, maintain, and operate the explosion in application development?
Our answer is Sazabi: the AI-native observability platform for fast-moving engineering teams.
Sazabi gives teams a single place to ask questions about their production systems in plain language, automatically visualize what's happening, and get to the root cause 10x faster. No tedious instrumentation. No dashboard configuration. No alert tuning. Just answers.
We're backed by tastemakers from the world's top AI companies: Vercel, Graphite, Daytona, Browserbase, LangChain, Mastra, Replit, and more.
What you’ll do
Build and scale our log ingestion and processing pipeline
Design systems for high-throughput, low-latency data processing
Own storage, indexing, and query systems for logs
Ensure reliability, scalability, and cost-efficiency of our backend systems
Work on distributed systems that power real-time observability
Debug and optimize performance at every layer of the stack
What we're looking for
Strong experience with distributed systems and data infrastructure
Familiarity with streaming systems, databases, and large-scale data pipelines
Deep understanding of performance tradeoffs (latency, throughput, cost)
Ability to design systems from scratch, not just maintain them
Comfort working close to the metal when needed
Bonus: experience with observability platforms, logging systems, or time-series data
Our tech
Our stack is TypeScript end-to-end. We use PostgreSQL for relational data, Temporal for durable execution, and the Vercel AI SDK to orchestrate our AI agents against the latest models. At the infrastructure layer, we use Terraform, Kubernetes, and AWS.
Some of the most interesting engineering problems we grapple with are:
AI agents at production scale
Log processing at scale
Multi-region data architecture
Real-time streaming infrastructure
Evals and reinforcement learning
Zero-downtime deployments and fast rollbacks
What we offer
Competitive salary and equity
Free lunches (in-office only)
Health, dental, and vision insurance
Unlimited paid time off
Paid parental leave
Learn how we think and work
Our team comes from Brex, Y Combinator, Rootly, Google, Doppel, and other top tech companies. We move fast and hold a high bar for both the product and each other.
We operate according to six values:
Integrity. We say what we mean, do what we say, and own our mistakes.
Urgency. We treat every week like it matters, because it does.
Craftsmanship. We care deeply about the quality of our work.
Service. We're here to make developers’ and our teammates’ lives easier.
Kindness. We're direct, and we move fast, but we treat each other well.
Fun. We genuinely enjoy working together. If you don't love what you're building and who you’re building it with, what's the point?

The Sazabi philosophy
Sazabi is more than just a tool. It’s also a philosophy. We're taking a radically different approach to observability, centered on three big ideas:
Less is more. Most observability platforms drown you in dashboards and modules that you don’t need. We believe observability needs less UI, not more. Sazabi surfaces exactly the information you need in a simple, beautiful chat interface.
Logs are all you need. The “three pillars of observability” idea is outdated. Sazabi accepts only one kind of telemetry: logs. This simplifies the instrumentation and product experience dramatically.
Monitoring is dead. Creating and maintaining static alerts for a fast-evolving system is a fool’s errand. The future is agentic anomaly detection: AI agents that automatically check your app for issues 24-7.
We came to these beliefs the hard way — after years of building infrastructure and responding to incidents with tools that offered plenty of bells and whistles, but no clear answers when it counted most.
If this way of thinking resonates with you, come build with us.
