Headquartered in Chicago, IL with a 2nd HQ in Bengaluru, India we are powered by a diverse global team that is tackling the toughest logistics challenges with innovation, urgency, and purpose. If you're driven to solve meaningful problems, leverage AI to scale rapidly, drive impact daily, and be part of a high-performance team - we should talk.

Description:

project44 is looking for a Senior Software Engineer to join our Visibility Platform team in Amsterdam. You will help shape the shared engineering foundation that powers every one of project44's visibility products - Ground (FTL, LTL, Parcel, Rail), Ocean, Air, and Orders - turning billions of carrier signals into real-time tracking, milestones, and notifications for the world's largest shippers and logistics providers.

Key accountabilities: What you'll work on

• Build and evolve the core platforms behind every visibility product - event ingestion, milestone computation, webhook and notification delivery, scheduled work, and shared APIs used across all modal teams.
• Design event-driven systems that process high-throughput carrier data reliably and with low latency.
• Own reliability, performance, and scalability of the platforms your team operates.
• Building systems in a multi-cloud environment. We use AWS and GCP but value experience in other cloud environments such as Azure.
• Partner with modal engineering teams across Ground (FTL, LTL, Parcel, Rail), Ocean, Air, and Orders to expose platform capabilities they can build on.
• Share ownership of all facets of software delivery, including development, operations,and test.
• You will assume on-call responsibilities for systems (together with the team) that are built and owned by your team.
• You will invest in tools, monitoring, and automation to improve on-call experience for everyone on your team.

Qualifications:

• 5+ years professional experience building large scale and real time or near real time cloud systems.
• Strong programming and debugging skills, with proficiency in Java Backend.
• Demonstrated experience with systems that operate at high scale - high event throughput, tight latency SLAs, and high availability as first-class design constraints, not stretch goals.
• Experience in:
  • Designing and operating event-driven and stream-processing systems on Kafka or Kinesis.
  • Creating and working with scalable Java-based micro-services.
  • Working with databases (preferably Postgres or other SQL based DB).
  • Building systems in a multi-cloud environment. We use AWS and GCP but value experience in other cloud environments such as Azure.
  • Working in an agile software development environment.
• Desirable and helpful (but not necessary) are experience in:
  • Building shared platforms consumed by other engineering teams - API design, versioning, and backward-compatibility considerations.
  • Experience with investigating large and complex codebases.
  • Hands-on experience with Java.
  • Creating API's/web services: REST, OpenAPI/Swagger is a plus.
  • Container-orchestration: Docker & Kubernetes.
  • Enjoy database related work: DynamoDB, MongoDB, Postgres.
  • Observability tooling (metrics, tracing, logs) and running production systems at scale.
  • Analytical approach to problem solving.
  • Personal drive and maintaining a high pace - while taking responsibility for things working.
  • Willingness to vocalize your ideas and pick yourself up if you get knocked down.

In-office Commitment:

This position requires a commitment to contribute to our collaborative culture by working in-office Three days weekly.
