Senior Software Developer Jobs in Rancho Palos Verdes, CA

BD is one of the largest global medical technology companies in the world. Advancing the world of health is our Purpose, and it's no small feat. It takes the imagination and passion of all of us-from design and engineering to the manufacturing and marketing of our billions of MedTech products per year-to look at the impossible and find transformative solutions that turn dreams into possibilities.

Summary:

We are looking for a Senior Software Developer in Test to own and evolve our automated test platform. This is a software engineering role first, you will design and build production-quality code that happens to verify software, not a testing role that occasionally writes scripts. You will architect test infrastructure, contribute to shared libraries. You are as comfortable reviewing a pull request as you are designing a new module from scratch.

The Senior Software Developer in Test will be a self-directed engineer who holds test code to the same standard as production code. They will bring strong software design instincts, a bias toward building reusable infrastructure over one-off scripts, and the communication skills to align with development teams on quality strategy. They'll thrive in environments where quality is an engineering discipline, not a phase.

Responsibilities:

• Design, build, and maintain a multi-module test infrastructure spanning API, browser, performance, and protocol-level testing disciplines.

• Develop and version reusable shared libraries, authentication clients, model libraries, device simulators, and data providers consumed across multiple test modules.

• Build software simulators for external systems and hardware devices to enable isolated, reproducible test environments independent of third-party availability

• Engineer layered API client abstractions that handle authentication, request construction, response validation, and structured logging

• Design and execute load simulations that model realistic concurrent user journeys, define SLO thresholds, and produce actionable results

• Author and maintain CI/CD pipeline definitions that execute, gate, and report on test results across environments and deployment targets

• Integrate test execution with external test management and defect tracking systems to maintain traceability from requirement to result

• Enforce production-grade engineering standards on test code, design patterns, code review, refactoring, and module-level abstractions

• Advise on API contracts, authentication flows, and system observability from a testability perspective during design and development

• Mentor engineers contributing to the test codebase and establish conventions that allow the platform to scale with the team

Minimum Required:

• Bachelor's degree, preferably in Software engineering/Computer science

• 3+ years of professional software development experience with a strong foundation in object-oriented design and clean code principles.

• Proficiency in Java; able to design and build maintainable, extensible code at module and library level

• Proven experience building test frameworks and shared libraries from scratch (not just writing tests within an existing one)

• Deep understanding of OAuth 2.0 authentication flows including client credentials, PKCE, bearer token injection, and thread-safe token refresh.

• Hands-on experience engineering browser automation frameworks including page object hierarchies, dynamic wait strategies, and failure diagnostics

• Experience designing and executing load simulations with realistic user journey modeling and JVM tuning for high-concurrency execution

• Proficiency with multi-module build systems, dependency management, and library versioning at scale

• Experience authoring and owning CI/CD pipeline definitions end-to-end, including containerized test environments

• Familiarity with structured test reporting, code coverage analysis, and static quality tooling

Preferred skills and knowledge:

• Experience building software simulators for external systems, APIs, or hardware devices communicating over non-HTTP protocols (WebSocket, MQTT, TCP, or similar)

• Familiarity with healthcare messaging standards such as HL7 v2.x or FHIR

• Experience integrating test results with test management or defect tracking platforms (e.g. Xray, Zephyr)

• Background in domains involving regulated, safety-critical, or medical device software

• Contributions to open-source testing or developer tooling

To find purpose in the possibilities, we need people who can see the bigger picture, who understand the human story that underpins everything we do. We welcome people with the imagination and drive to help us reinvent the future of healthcare. At BD, you'll discover a culture in which you can learn, grow and thrive.

We believe that when people connect in person, we learn faster, collaborate more deeply, and build a stronger culture. Join us and enjoy a culture where face-to-face collaboration supports your learning, your progress, and your success.
