• Identify and measure levers to help move essential metrics and make recommendations

• Work backwards from understanding and sizing problems to ideating solutions

• Report against our goals by identifying essential metrics and building executive-facing dashboards to track progress

• Collaborate with engineering to implement, document, validate, and monitor our logging

We're excited about you because you have…

• A degree in Math, Physics, Statistics, Economics, Computer Science, or a similar domain

• 2+ years of experience in data analytics, consulting, or related role

• Experience working with funnel optimization, user segmentation, cohort analyses, time series analyses, regression models, etc

• Expertise of SQL queries, ETL, A/B Testing, and statistical analysis (e.g. hypothesis testing, experimentation, regressions) with statistical packages, such as Matlab, R, SAS or Python

• Proficiency in one or more analytics & visualization tools (e.g. Chartio, Looker, Tableau)

• The insight to take ambiguous problems and solve them in a structured, hypothesis-driven, data-supported way

About the Team

The Storage teams build and operate online stateful systems and abstractions that are reliable, efficient, secure and easy to use for DoorDash Engineering. The teams are responsible for understanding Product Engineering’s evolving needs and developing platform and infrastructure capabilities to serve them. The team currently supports CockroachDB, Cassandra, Kafka and Redis as well as data abstraction services to reduce the complexity of interacting with storage systems for Product Engineers.

About the Role

We’re hiring a Data Solutions Engineer with deep expertise in distributed databases, particularly Apache Cassandra, Redis, Kafka, and database agnostic abstractions. In this role, you will design, optimize, and scale distributed data access layers that power DoorDash’s most critical systems, ensuring high availability, low latency, and fault tolerance.

You’ll serve as a hands-on architect and technical partner to product engineering and infrastructure teams, helping translate complex business requirements into resilient and scalable data models. Your work will directly influence the evolution of Taulu , DoorDash’s unified storage abstraction layer, by shaping best practices and identifying platform gaps through real world engagements.

This is a high-impact, cross functional role that combines deep technical expertise with a customer centric approach. You’ll lead solutioning engagements from design through production, drive the adoption of Taulu modeling best practices, and ensure that our systems meet goals around reliability, cost efficiency, and velocity. You must be located in San Francisco, Sunnyvale, Seattle or New York for this hybrid opportunity.

You’re excited about this opportunity because you will…

• Design and implement highly scalable, fault tolerant distributed database solutions using Taulu, Apache Cassandra, Redis, Kafka, and other paved path storage solutions.

• Architect and optimize multi-region, globally distributed systems to meet our high standards for availability, latency, and throughput.

• Lead data modeling, performance tuning, and capacity planning for large-scale, mission-critical storage workloads.

• Partner with product engineering and infrastructure teams to deeply understand domain specific data needs and guide them in adopting paved path storage solutions.

• Serve as the DRI for solutioning engagements , owning modeling in Taulu from experimentation through launch and scale.

• Shape the evolution of Taulu by identifying abstraction gaps and converting customer feedback into platform improvements.

• Apply workload-aware design patterns, including caching strategies, partitioning, and consistency tuning to improve performance and efficiency.

• Drive adoption of operational best practices across observability, schema design, capacity planning, and cost optimization across storage systems.

• Promote clarity and continuity by contributing to solutioning playbooks, decision logs, and architectural documentation.

We’re excited
