About the role

The Logistics Foundation team is a cornerstone of Instacart's fulfillment platform, advancing foundational systems that power earnings, pricing, routing, batching, matching, dispatch, and geospatial capabilities.
Our mission is to unlock new capabilities and business impact through scalable, reliable architecture that elevates both engineers and AI agents, enabling efficient, compliant logistics at scale.
You'll join a high-impact group of approximately 15 engineers within a broader Logistics Serving and Foundation organization of about 30 engineers.

You thrive in fast-paced, ambiguous environments, communicate clearly with technical and non-technical partners, and take ownership to deliver durable solutions under tight deadlines.
In this role, you will collaborate closely with cross-functional partners across Legal, Finance, Policy, Shopper, Enterprise Fulfillment, Operations, and Expansions to deliver resilient systems against hard external deadlines.
Own and drive complex platform workstreams end-to-end - from engineering design docs through implementation, launch coordination, war room monitoring, and ongoing support.
Design, build, and operate high-quality, high-throughput distributed backend services with clear SLOs, robust observability, and well-run on-call/incident response practices.
Establish and champion engineering standards through rigorous design reviews, production readiness, on-call ownership, and continuous improvement of instrumentation and alerting.

7+ years of backend software development experience delivering scalable, production systems end-to-end.
Proficiency in at least one backend language such as Ruby, Python, or Go.
Proven track record independently leading complex, cross-functional projects with high ambiguity and hard external deadlines.
Bachelor's degree in Computer Science or a related field, or equivalent practical experience.

Experience with compliance-sensitive systems (e.g., pay systems, SOX, GDPR, government policy/labor regulations).
Technical experience with Ruby on Rails, Python, Golang, Postgres, Redis, and AWS.
Experience with geospatial systems, mapping, or multi-jurisdiction rule engines.
Familiarity with marketplace or logistics domain problems.
Proficiency in system performance optimization, including CPU utilization, load balancing, and latency reduction.
Experience collaborating across teams to advocate for and land platform-wide solutions.
Skilled at leveraging AI to enhance engineering velocity and efficiency.
Offers may vary based on many factors, such as candidate experience and skills required for the role.
