Senior Software Engineer (Python/React)

Architect the Future of Logistics: Senior Full Stack Software Engineer! About Us: Trimble is a leading provider of technology solutions that connect the physical and digital worlds. Transporeon, part of Trimble's Transportation & Logistics division, operates one of the world's largest freight collaboration platforms, processing millions of transport orders annually across global markets. About the Role: Join our Autonomous Procurement - Applications & API Team as a Senior Software Engineer to design and build full-stack features that power robust applications and APIs that enable efficient procurement and carrier management. You'll work with cutting-edge technologies including machine learning and large language models to deliver intelligent, automated solutions using React, Python, AWS, and Azure. Our globally distributed, async-first team values autonomy, quality craftsmanship, and pragmatic problem-solving. We prioritize deep work by defaulting to Slack & Notion for collaboration, keeping synchronous meetings to a purposeful minimum. We ship iteratively, prioritize clear communication, and believe in raising the engineering bar through continuous engineering excellence and career development. About Autonomous Procurement: You'll be developing and owning solutions that power our Autonomous Procurement (AP) platform—our next-generation closed-spot procurement product that enables shippers to efficiently source transport capacity from their trusted carrier networks. AP delivers significant value to our customers by streamlining procurement workflows, reducing manual effort, and accelerating time-to-award while maintaining full control over their carrier selection. Responsibilities: * Design and implement highly available, scalable backend services and APIs that orchestrate complex procurement workflows across distributed systems (REST; service-to-service communication; event-driven architectures) * Architect resilient service designs and data models that handle high-volume transaction processing, ensuring performance under load and graceful degradation * Continuously improve reliability, performance, and scalability through profiling, observability, and load testing * Implement comprehensive security, data protection, and fault-tolerance patterns for critical procurement operations * Build and optimize asynchronous task processing pipelines for automated procurement decisions and carrier notifications * Design caching strategies, database optimization, and service orchestration patterns to achieve sub-second response times at scale * Build, test, and ship user-facing web experiences with high performance and accessibility * Contribute in architecting and designing scalable frontend architecture * Own entire features from specification to shipping, including technical planning, estimation, and rollout * Collaborate with product managers and designers to shape solutions and deliver iteratively * Work effectively with a high degree of autonomy in a globally distributed, async-first team * Participate in code reviews, raise engineering standards, and reduce technical debt through pragmatic refactors * Leverage AI-assisted development tools to accelerate feature delivery, refactoring, and debugging while maintaining code quality, test coverage, and system observability * Mentor junior developers and help establish coding standards and best practices Requirements: * 5+ years of professional software engineering experience, including meaningful ownership of production systems * Strong backend experience building services in Python (Python 3) in cloud environments (AWS) * Experience with common backend patterns and tools (Flask, Celery, PyTest or similar) * Solid database skills with PostgreSQL (schema design, indexing, query performance) * Familiarity with distributed systems and microservices architecture; ability to reason about tradeoffs * Experience using AI-assisted development...
