Position Summary:
We’re looking for a Senior Software Engineer to help modernize the technology behind USPS shipping. You’ll join the small, high-trust team that owns EasyPost’s most critical, highest-traffic platform — the USPS PC Postage system — and play a key role in our journey to the cloud. Your Go expertise will help refactor legacy services, design cloud-native solutions, and deliver the low-latency, high-throughput systems our customers count on every day. If you thrive on solving complex engineering challenges and want to shape a platform that handles massive scale and real-world impact, this is the role for you.
Essential Duties and Responsibilities:
The essential functions include, but are not limited to the following:
o Build the future - design, code, test, and optimize high-performance Go services that power USPS shipping for millions of users.
o Drive the migration - help refactor legacy systems for the cloud, then design new cloud-native services that take full advantage of Azure, Kubernetes, Kafka, and more.
o Collaborate and influence - work hand-in-hand with product managers and other engineers to translate big ideas into rock-solid architecture.
o Raise the bar - participate in peer reviews, mentor teammates, and bring modern Go best practices (gRPC, microservices patterns, performance tuning) into the codebase.
o Solve real problems - troubleshoot production issues in high-throughput, low-latency environments without downtime.
o Document for the future - create clear technical docs so the next engineer can pick up right where you left off.
o Continuously improve - bring fresh ideas from the industry to improve speed, scalability, reliability, and developer experience.
o Test like you mean it - build and run automated unit, integration, and performance tests to ensure we ship with confidence.
o Work smart with tools - use Git and other version control systems to manage complex, distributed workflows.
Minimum Education & Experience Qualifications:
o Bachelor’s Degree
o 8+ years of software development experience, master’s degree and 6+ years of software development experience, or equivalent related work experience.
o Proven experience in software development, including designing, coding, testing, and debugging applications.
o Proficiency in Go; experience with additional languages such as Python, C++, or similar is a plus.
o Familiarity with Agile or Scrum methodologies and tools like JIRA and Confluence.
o Strong understanding of data structures, algorithms, and design principles.
o Experience with backend frameworks and APIs; familiarity with front-end frameworks such as React, Angular, or similar is a plus.
o Knowledge of SQL and NoSQL databases and data modeling concepts.
o Excellent analytical, troubleshooting, and problem-solving skills.
o Strong verbal and written communication skills, with the ability to convey complex ideas to technical and non-technical audiences.
Core Competencies Required:
o Big-picture thinker, hands-on builder - you understand how systems fit together and can move seamlessly from high-level architecture to production-ready code, improving what’s there while respecting the work that came before.
o Creative problem-solver - you thrive on solving complex engineering challenges, weighing trade-offs, and delivering solutions that work in the real world.
o Collaborative influencer - you connect with teammates across disciplines, earn trust quickly, and know how to communicate ideas that inspire action.
o Adaptable leader - you’re comfortable in ambiguity, able to chart a path forward, and you elevate the people and projects around you.
