The Senior Software Engineer will play a key role in strengthening and modernizing aPriori’s legacy product portfolio, with a focus on our best‑in‑class automation solutions. Working with a distributed team of engineers, you will design, develop, and evolve complex enterprise applications that power our manufacturing insights platform. This role combines hands‑on software development with technical leadership, balancing new feature delivery, modernization efforts, and quality improvements.

Our technology stack includes Java with Spring Boot, PostgreSQL, REST APIs, React/TypeScript, Redis, and Docker, all deployed in AWS. Experience with containerized, distributed SaaS applications is essential, along with the ability to mentor and guide teams toward best practices in design, testing, and delivery.

Responsibilities

• Lead technical design and implementation of new product features and enhancements.
• Modernize and refactor existing codebases for scalability, maintainability, and cloud readiness.
• Provide day‑to‑day technical direction and mentorship for a mixed team of internal and contract developers.
• Collaborate with product and architecture teams to ensure consistent technical alignment across applications.
• Provide clear and concise progress updates, risks, and trade‑offs to management to support informed decision‑making.
• Clearly articulate complex technical concepts to non‑technical stakeholders and management.
• Build and maintain automated CI/CD pipelines using Docker and Kubernetes.

Requirements

• Working knowledge of Docker and AWS‑based SaaS environments.
• Strong understanding of code quality practices, including unit testing, CI/CD automation, and automated code scans for both quality and security.
• Skilled in PostgreSQL and Redis in production systems.
• Experience designing or building analytical / reporting APIs, including considerations like data aggregation, query performance, and consumer‑friendly response shaping, is a plus.
• Familiarity with API Gateway concepts and patterns (e.g.: routing, rate limiting, auth delegation).
• Experience with customer‑facing, productized APIs and the platform underpinnings that support them is a plus.
• Familiarity with modern workflow orchestration tools (e.g. Apache Airflow, Temporal, etc) for managing and automating data or processing pipelines is a plus.
• Self‑starter with the ability to work as part of a global project team.

Education and Experience

• 7+ years of professional software engineering experience.
• 3+ years of hands‑on experience with Java and Spring Boot.
• Bachelor’s degree in Computer Science or a related field.
