You will join a team of software developers to plan and implement test cases and execute them to verify the embedded software modules on Embedded Linux or TI RTOS platforms primarily using C++ programming language and Scripts to control, manage and drive sophisticated Mass Spectrometry, Chromatography instrument software and their workflows. Define the scope of embedded software testing within the context of each Software releases or Engineering releases and support execution. Writing Test strategies, Test objectives, Testing scenarios, and test environment etc. after a thorough analysis. Estimate the testing efforts. Execute test cases described and documented in the test plan during the development cycle and assist in debugging issues in hardware and software to determine root cause.
Define and execute strategies to automate tests to improve performance of testing cycle. Work independently in a team to conduct complex software testing activities. Good exposure on End-to-End testing. The software controls various systems and devices like RF generators, motors, pumps, heaters, and other peripherals for processing of samples and generating analytical data. Firmware testing is critical to achieve high-level of firmware quality demanded by customers.
Roles & Responsibilities
Responsible for defining the scope of embedded software testing within the context of each software releases and support execution
Executing the tests to verify the changes in CPP and C programs in Embedded Linux firmware for mass spectrometer products.
Identify opportunities for automating the testing conditions during the software development life cycle
Responsible for setting up Lab infra prototype board setups for firmware development
Work with global software team members to deliver complete and high-quality instrument control software applications to schedule and specification.
Captures test requirements & plan tests and environment setup for execution.
Provides near to accurate time estimates on test planning of these requirements.
Clearly articulates test cases with pass criteria. Performs testing, documents test results, reviews the test data & analyses failures interdependently with root cause and counter measures to fix the issues
Leverages peer review & communicates openly to find options to simplify tasks. Adopt platform strategy and practice standard design rules/patterns
Constant learner to become a domain expert.
