Senior Software Engineer Ii, Logistic Foundation

Instacart Instacart · Consumer · United States · Remote · Software Engineering

Senior Software Engineer II on the Logistics Foundation team at Instacart, focusing on building and operating scalable, reliable backend services for core logistics functions like pricing, routing, and dispatch. The role involves end-to-end ownership of platform initiatives, collaboration with cross-functional teams (including Legal and Finance for compliance), and driving the adoption of modern technologies and AI toolsets to improve engineering velocity and quality. Requires strong backend development experience, distributed systems knowledge, and experience with compliance-sensitive systems.

What you'd actually do

  1. Own and drive complex platform workstreams end-to-end — from engineering design docs through implementation, launch coordination, war room monitoring, and ongoing support.
  2. Design, build, and operate high-quality, high-throughput distributed backend services with clear SLOs, robust observability, and well-run on-call/incident response practices.
  3. Analyze and refine service and data architectures; propose and lead new systems that improve reliability, scalability, and operational excellence.
  4. Establish and champion engineering standards through rigorous design reviews, production readiness, on-call ownership, and continuous improvement of instrumentation and alerting.
  5. Partner with Legal, Finance, and Policy to deliver compliance-ready solutions across multiple jurisdictions and regulatory frameworks, balancing urgency with long-term maintainability.

Skills

Required

  • 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.
  • Hands-on experience building and operating large-scale distributed backend services with defined SLOs, on-call ownership, observability, and incident response.
  • Proven track record independently leading complex, cross-functional projects with high ambiguity and hard external deadlines.
  • Exceptional written and verbal communication skills, including authoring technical artifacts (e.g., ERDs, design docs) and coordinating launches with non-engineering stakeholders.
  • Bachelor’s degree in Computer Science or a related field, or equivalent practical experience.

Nice to have

  • 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.
