Opus have partnered with a UK-based Critical Communications provider who's technology supports real-time messaging and alerting systems used by major data centre operators, large-scale healthcare and emergency services organisations.This will be a hands on contract role with strategic influence, where you'll be responsible for defining and implementing a robust and cohesive end-to-end testing strategy, working closely with engineering and product leadership in a fast-pace, environment with a start-up feel.
The key challenge is bringing structure and maturity to a fragmented testing landscape, establishing a cohesive end-to-end strategy across complex, multi-channel and highly integrated systems.
Challenge:

There is a need to improve documentation, particularly around user journeys, acceptance criteria, and customer-facing content.
