Role Description

As a Senior Platform Engineer on the Data Platform team, you will be responsible for designing, implementing, and maintaining the data models, data access patterns, contracts, database infrastructure, and instrumentation that power our transactional systems. You will be at the intersection of every major engineering initiative, working across Product Engineering, Analytics, ML, and Platform to set the bar for data quality, consistency, usability, scalability, and security. You will ensure great data starts at the moment a feature is built, not as a cleanup task afterward. You'll also own one of the team's most impactful initiatives: designing and migrating to modern data models that reflect how our business works at scale.

We’re a team of passionate, forward-thinking professionals eager to take on the challenge of the mental health crisis and play a formative role in providing life-saving solutions. If you’re inspired by our mission and energized by the opportunity to increase access to mental healthcare and profoundly impact millions of lives, apply today.

• Experience with observability, monitoring, and logging tools such as Datadog and Cloudwatch.
• Proven track record of breaking down large problems and delivering incremental value to meet deadlines while providing options for long-term improvements.
• Ability to troubleshoot complex distributed systems.
• Familiarity with AI-enabled developer productivity tooling.
• Strong communication and problem-solving skills, and the ability to work in a fast-paced startup environment.
