Principal Engineer Quality Assurance

YOUR FUTURE ON DEMAND

The ideal blend of stability and flexibility. A genuinely human employer that cares for people and the planet. True autonomy to shape what comes next for us and you. This is the perfect platform to take your career where you want.

Back in 2005 we pioneered Europes first TV streaming service. Today were a leading TV streaming provider with millions of monthly users and since 2021 weve been ClimatePartner-certified. Over 200 colleagues of 47 nationalities. Were the grown-up start-up helping to shape a better future since day hasnt changed even if the world has. Were friendly international inclusive and our people say were reliable and transparent too. Its why they trust us and believe in what we do.

THE ROLE

We are looking for a Principal Engineer QA as a senior individual contributor. You will define how quality risk is assessed measured and gated across the full streaming path - and embed that craft into engineering teams who own day-to-day tests and suite health.

• Quality strategy & risk - Build and maintain a living risk model for the streaming chain. Raise effort where failure hurts most. Make coverage vs. speed and pre-release vs. production trade-offs explicit with product and eng.
• Release constraints & quality gates - Define what releasable means for backend middleware and clients - including how continuous backend/middleware delivery is gated relative to client store cadences (web/TV/mobile). Keep gates fast trustworthy and hard to bypass.
• Rollout practice (build with the teams) - Define and establish staged rollout canary and rollback strategies together with eng and SRE/ops. Own the definition; establish and operate them collaboratively.
• Test architecture - Set the pyramid and ownership boundaries (unit through E2E performance playback/stream validation) so each layer has a clear home inside eng. Drive cross-stack design that exercises real policy and format decisions.
• Incident & reliability partnership - Join major quality incidents with a quality lens; strengthen production feedback for streaming health; turn escapes into durable tests monitors gate changes and rollout improvements.
• Tooling & automation standards - Set practical standards for frameworks CI integration test data environments and reporting so teams share patterns with clear ownership and measurable ROI.
• AI-enabled quality engineering - Define where AI raises quality leverage: test generation and maintenance risk-based test selection failure triage and incident analysis. Set standards for AI-assisted testing and shape quality expectations for AI-authored code as delivery speed and change volume increase.
• Mentoring & influence - Embed quality craft into eng: risk-based testing quality in PRs middleware policy and multi-platform client testing. Socialize lightweight strong-default standards (definition of done flake policy critical-path coverage). Influence design reviews when quality risk is material.

• Org-wide quality strategy risk model and whole-stack standards
• Release constraints and quality gates; definition of releasable
• Definition of staged rollout/canary/rollback strategies (to be established with partners)
• Test architecture principles and automation norms
• Cross-stack escape analysis and quality debt for gates and tooling
• Embedding quality craft in engineering; influencing high-risk designs
• Standards for AI-assisted testing and quality expectations for AI-authored code

• Engineering - They implement and own tests/suites in services and clients; you set architecture gates and standards and build quality practice into delivery.
• Product - Journey and tenant/feature priority; acceptance of residual risk within the gates you define.
• SRE / Ops - Establish and operate rollout strategies together; production signals incident response capacity/reliability.
• Platform/tooling - CI environments shared frameworks observability for quality signals.

• Track record as a senior IC in quality engineering (or equivalent) for complex multi-service products - ideally streaming media or similarly high-availability consumer platforms
• Experience designing whole-stack quality strategy: backend services configuration/policy layers and multi-platform clients
• Ability to define and land test architecture (pyramid ownership cross-stack integration/contract/playback-style validation) that engineering teams can run and own
• Strong influence without authority: you raise the bar inside eng teams socialize standards and hold the line on gates without managing a QA org
• Strong software engineering skills at senior level or above; you write production-quality code not just test scripts
• Designing and coding for testability and building automation as a first-class engineering product
• Deep familiarity with CI/CD with a track record of making pipelines faster and more reliable
• Hands-on experience applying AI to quality engineering with judgment on where it reduces risk and where it adds noise
• Comfort partnering on incidents and turning production failure modes into durable quality improvements
• Practical judgment on automation: enough to protect risk not so much that brittle suites block the org
• Bonus:
  • Hands-on engineering background with video ingest encoding/packaging playback or multi-tenant config/policy surfaces
  • Work across web TV and mobile client quality risk (device/OS/store constraints)
