About the role

  • This role is product-facing, but we're specifically looking for an infrastructure-minded engineer.
  • You'll be working on a team that will focus on improving our shared services, frameworks, tooling, and deploy infrastructure, not just our product.

Responsibilities

  • Drive Technical Delivery: Lead substantial technical initiatives from concept to production, ensuring inter-team dependencies are accounted for.
  • Build on (and Improve) the Platform: Write, test, and deploy production-quality code in Node.js/TypeScript/PostgreSQL, with React/React Native for web and mobile. Find bottlenecks and improve, or rethink, our architecture when it's a bottleneck.
  • Architect for Scale: Design message-driven workflows (Kafka/SQS/RabbitMQ) and distributed systems that handle the complexities of a real-time marketplace.
  • Raise the Infra Bar Across the Org: Identify and drive cross-cutting improvements to shared libraries, CI/CD pipelines, developer tooling, observability, and Kubernetes/Terraform infrastructure. Make other teams faster and safer, not just your own.
  • Own the Lifecycle: Manage the full software lifecycle in a high-ownership, low-process environment - observability, incident response, safe rollouts, and performance tuning.
  • Collaborate & Mentor: Partner with Product, Data Science, Platform, and business stakeholders to solve ambiguous problems. Mentor junior en
  • Platform/Infra Sensibility: Experience building or improving the foundations other engineers rely on, such as shared libraries, frameworks, CLIs, CI/CD, or developer tooling, with attention to backward compatibility and migration paths.
  • With nearly 700 teammates across offices in Denver, CO; Portland, OR; Seattle, WA; Springfield, MO; Toronto, ON; and Bangalore, India, DAT combines the credibility of a multi-decade market leader with the drive of a company that is not done disrupting the industry it helped build.

Requirements

  • 7+ years of professional software engineering experience with a proven track record of shipping impactful products.
  • Backend Mastery: Strong proficiency with TypeScript and Node.js, including API design and debugging in production environments.
  • Messaging & Cloud: Hands-on experience with message queues ( Kafka or RabbitMQ) and cloud-native deployments (AWS).
  • You are comfortable breaking down complex, undefined problems.
  • Communication: Excellent ability to advocate for technical direction and communicate progress to non-technical stakeholders.
  • Specialized Domains: Experience in logistics, fintech/payments, fraud prevention, or two-sided marketplaces.
  • Developer Experience: Built local dev environments, code generators, or tooling used by other engineering teams.

Nice to have

  • Proficiency with SQL (PostgreSQL preferred) including schema design, migrations, and query performance.
  • Production experience operating services on Kubernetes, and familiarity with service mesh concepts.
  • Direct experience with Istio, or Envoy is a strong plus.
  • Data Expertise: Proficiency with SQL (PostgreSQL preferred) including schema design, migrations, and query performance.
  • Orchestration & Networking: Production experience operating services on Kubernetes, and familiarity with service mesh concepts.
