Job description

Senior Software Engineer, Data Foundation

About Mixpanel

Mixpanel turns data clarity into innovation. Trusted by more than 29,000 companies, including Workday, Pinterest, LG, and Rakuten Viber, Mixpanel’s AI‑first digital analytics help teams accelerate adoption, improve retention, and ship with confidence. Powering this is an industry-leading platform that combines product and web analytics, session replay, experimentation, feature flags, and metric trees. Mixpanel delivers insights that customers trust.

About The Role

Data governance is one of the most critical challenges for Mixpanel's enterprise customers, and the AI era turns it into a foundational problem. Analytics and agents are only as trustworthy as the data beneath them. Poor data quality compounds: incorrect analyses spread as it becomes easier for anyone — or any agent — to query data, and the problem multiplies as customers scale into projects with high‑cardinality events and fast‑growing user bases. A data foundation that stays clean, consistent, and trusted is what sets Mixpanel apart.

As a Senior Software Engineer on the Data Foundation team, you'll work across the stack to build high‑impact features with extreme customer focus. You'll partner closely with engineers across the company, and with Design, Product, and GTM, to solve one of the hardest problems in analytics: keeping data clean, consistent, and trustworthy at scale.

• Build customer‑facing features on our web application (React SPA)
• Collaborate closely with engineers and cross‑functional partners across Product, Design, GTM, and beyond
• Take full ownership of projects — from shaping and delivery through iteration

We're Looking For Someone Who Has

• Full‑stack experience, with deep expertise in at least one of:
  • Web application backends (Python, Django)
  • High‑volume APIs
  • Search indexing
• A track record of leading projects end to end, not just executing tickets
• Comfort moving across the stack

Bonus Points For

• Experience with data ingestion (Go)
• A data‑driven or metrics‑focused approach to decision‑making

Example Projects You Might Work On

• Advanced Delete
• Data Volume Monitoring and Anomaly Detection

Culture Values

• Make Bold Bets: We choose courageous action over comfortable progress.
• Innovate with Insight: We tackle decisions with rigor and judgment - combining data, experience and collective wisdom to drive powerful outcomes.
• One Team: We collaborate across boundaries to achieve far greater impact than any of us could accomplish alone.
• Candor with Connection: We build meaningful relationships that enable honest feedback and direct conversations.
• Champion the Customer: We seek to deeply understand our customers’ needs, ensuring their success is our north star.
• Powerful Simplicity: We find elegant solutions to complex problems, making sophisticated things accessible.
