Software Coding Jobs in Maine (NOW HIRING)

Job Description ONSITE - Westbrook, ME (Hybrid 2x per week) We're looking for a Senior Software Engineer to help shape the platform powering our diagnostic data services. Our team builds and maintains the APIs that deliver reliable, performant data to internal teams and external partners. You'll work across the full lifecycle - from design through deployment and ongoing support - partnering with analysts, product managers, and other engineers to turn business needs into systems people can depend on.

What you'll do: Design, build, test, debug, and document software based on technical configurations developed with analysts and project teams. Estimate and track effort to support project planning and financial tracking. Translate technical configurations into program designs that operate efficiently and reliably.

Understand the business function the application supports and ensure your design integrates cleanly with related systems. Write production code in the languages and frameworks best suited to the problem at hand. Test and debug rigorously to ensure smooth, predictable operation in production.

Document program design, code, and operational details so others can develop, use, and maintain the systems you build. Support, update, and maintain existing systems in response to business needs, defects, and changing requirements. Coordinate with project teams to design, code, test, and document changes.

Partner with project team members to define application requirements - identifying business needs, evaluating available technologies, and presenting clear, well-reasoned solutions. Contribute to system architecture decisions, particularly for the services and APIs your team owns. You'll occasionally be on call.

What you need to be successful: 5+ years of professional software engineering experience, with a track record of shipping and maintaining production systems. Strong proficiency in Java and Spring Boot, and/or Node.js with TypeScript, building and operating production APIs. Hands-on experience designing and building RESTful APIs that are reliable, performant, well-documented, and easy for partners to integrate against

Solid understanding of both relational (SQL) and NoSQL databases - comfortable with schema and data-model design, query tuning, and reasoning about data correctness. Hands-on experience with document stores such as Amazon DocumentDB and Google Cloud Datastore is a plus. Familiarity with cloud service providers, particularly Amazon Web Services and Google Cloud Platform - including the services typically used to run and observe API workloads (compute, storage, messaging, monitoring).

Experience with modern engineering practices: version control (Git), automated testing, CI/CD, code review, and incremental delivery. Strong written and verbal communication skills - you can explain technical trade-offs to engineers and non-engineers alike, and your documentation is clear enough that the next person doesn't need to ask. A collaborative mindset and a strong sense of ownership - you take problems to completion and care about the experience of the people using what you build.

"Nice to Have": Experience working with healthcare, life sciences, or diagnostic data, and an appreciation for the privacy and reliability standards those domains require. Exposure to event-driven architectures, message brokers (e.g., Kafka, Pub/Sub, SQS), or streaming data pipelines. Experience with containerization (Docker) and orchestration (Kubernetes, ECS, or GKE)

Familiarity with infrastructure-as-code tools such as Terraform or CloudFormation. Experience mentoring other engineers and helping shape team-wide engineering practices. Builds computer applications to meet business informational needs and requirements.

Designs, codes, tests, debugs and documents programs based on technical configurations developed by analysts and project teams. Supports and troubleshoots existing applications. Evaluates and analyzes business requirements for new systems and system changes.
