About The TeamMixpanel Engineering is a small, fast-moving team focused on delivering real value to customers. We build powerful AI-powered product analytics while obsessing over clarity, simplicity, and delight. Engineers here own problems end to end. You can move across the stack to ship impact without being blocked by silos or heavy process. Product innovation drives our business, and product engineering teams own that responsibility.
Our OLAP engine queries over 500 trillion events; a typical blob storage system we interact with processes 300 PiB/month at 1.2 Tbps sustained, and we run many of them across the world.
The Data Runtime team owns the data execution layer that powers every Mixpanel product. We ensure that every customer query runs fast, cheap, and reliably, at any scale.
This is an exciting time to join. Mixpanel's agentic and AI-first products are driving rapid growth in query volume, and Data Runtime is making the big bets that power it. We’re investing in elastic query compute and a distributed file cache that will let us scale query workloads dramatically without scaling cost with them. We sit at the center of the data platform, interfacing daily with Query Serving, Streaming, Core Analysis, Data Foundation, Product, and other teams across the company.
The team combines deep expertise in high-scale distributed systems and backend engineering. It's a senior-heavy team, including Staff-level engineers with years of context in the engine internals, which means you'll be surrounded by people you can learn from and grow with.
About The RoleAs a Software Engineer III (L3) on Data Runtime, you'll design and build the systems that execute every query at Mixpanel. You'll contribute to the technical design for complex distributed-systems projects, from prototype to global rollout, on initiatives like elastic query compute, the distributed file cache, columnar storage internals, and compaction.
You'll work alongside some of the most senior engineers at Mixpanel, partner with peer infrastructure teams (Query Serving, Streaming, Data Foundation) and product teams (Core Analysis, AI-powered experiences) on shared architecture, and have real influence over the technical direction of the compute layer that Mixpanel's AI-first future runs on.
We're Looking For Someone Who Has- Bachelor's degree in Computer Science, a related field, or equivalent practical experience.
- 3+ years of professional software engineering experience building and operating data infra/backend systems, with a track record of shipping quality work quickly.
- A solid foundation in distributed systems or data infrastructure, and the drive to go deep.
- Experience owning a project or significant component end to end: driving the design, building it, shipping it, and running it in production.
- Strong technical communication, especially in writing, e.g., design docs, code review, async discussion across a distributed team.
- Sound judgment in technical tradeoffs, informed by real lessons from operating systems in production.
- High ownership and accountability.
- A desire to be at the forefront of the infrastructure powering AI-first analytics at thousands of companies.
- Languages: Go, C/C++, Python, and SQL.
- Distributed systems: sharding/partitioning, replication, distributed scheduling, work fanout/merge, consistent hashing.
- Storage & query engines: columnar formats (Arrow/Parquet or in-house equivalents), indexing, and compression.
- Caching: distributed file/block caches, admission and eviction policies, tiered storage.
- Performance engineering: profiling (pprof, perf), concurrency, memory management, benchmarking.
- Cloud & infra: GCP (GCS, GKE, Spanner) or equivalent AWS/Azure, Kubernetes.
- Reliability: observability (metrics, tracing, logging), SLOs, incident management.
- AI-augmented engineering: LLM tooling to accelerate development, triage, and operations.
- Teams operate as autonomous pods, with engineering, product, and design working side by side on clear strategic goals. Teams have direct access to customer feedback, product usage data, business metrics, and design context.
- We start with customer problems. We reason from first principles. We challenge assumptions. We aim for simple solutions to complex problems and avoid unnecessary abstraction.
- Engineering owns execution, quality, and operations. There are no project managers, QA teams, or separate SREs. Ownership stays with the people building the product.
- We value written thinking, dashboards, and demos over slide decks. We work openly using tools like Slack, GitHub, Mixpanel, Notion, Figma, and Zoom — and we lean heavily on AI-assisted development (Claude Code and beyond).
- Our team is distributed across North America, with strong clusters in the San Francisco Bay Area and New York.
