Full Job Description

Summary:

The Software Development Engineer in Test ( SDET) position will be responsible for developing automated tests to ensure the quality of software systems and applications. The role involves creating test plans, writing code for automating tests, maintaining existing tests, and reporting on product defects. The SDET will work closely with developers and other stakeholders to identify issues early in development cycles and provide feedback to improve overall system reliability. This position requires strong technical skills as well as excellent communication abilities.

About the Role

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.

What We Are Looking For

A self-directed engineer who holds test code to the same standard as production code. You 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. You 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 Qualifications Required:

  • 5+ 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

At BD, we prioritize on-site collaboration because we believe it fosters creativity, innovation, and effective problem-solving, which are essential in the fast-paced healthcare industry. For most roles, we require a minimum of 4 days of in-office presence per week to maintain our culture of excellence and ensure smooth operations, while also recognizing the importance of flexibility and work-life balance. Remote or field-based positions will have different workplace arrangements which will be indicated in the job posting.

For certain roles at BD, employment is contingent upon the Company’s receipt of sufficient proof that you are fully vaccinated against COVID-19. In some locations, testing for COVID-19 may be available and/or required. Consistent with BD’s Workplace Accommodations Policy, requests for accommodation will be considered pursuant to applicable law.
