Hello everyone! Planning to submit this window and would love a sanity check from this community.
About me: Senior QA Automation Engineer since March 2022 at a venture-backed London adtech company (privacy-preserving, decentralised advertising technology serving 3,000+ publishers, reaching ~678M monthly active users and powering around 80% of the UK’s top publishers). I moved to the UK in 2024 on a Skilled Worker visa sponsored by the same company and remain on that visa today.
Mandatory Criterion
- Led the company’s QA engineering standards through sole authorship and ongoing ownership of its formal QA Test Strategy/Test Plan for more than two years, with dated CTO approval and documented technical collaboration. The document defines engineering quality standards, release governance and testing processes used across the development lifecycle.
- Took on recurring project delivery responsibilities in the absence of a dedicated Project Manager, coordinating engineering and product teams through sprint planning, delivery tracking and release activities alongside my QA role.
- Independent third-party recognition through Test IO as a “Great Tester” (top 5% globally): 1,291 completed test cycles, 1,392 approved bugs and 75 five-star ratings, achieved before joining my current employer.
OC1 (Innovation)
- Identified a previously unrecognised operational reliability gap specific to a privacy-preserving, decentralised advertising platform operating across thousands of publisher domains. Authored the engineering requirements and operating model for a permanent platform capability introducing controlled domain lifecycle management, audit logging and automated safety validation before production changes. The proposal was reviewed, approved and adopted by the CTO and engineering team.
- The platform itself has also received external recognition (I-COM Data Startup Challenge 2023 winner and participation in the Innovate UK EDGE Global Explorers Programme 2024). I am using these as contextual evidence of the innovative environment rather than as personal awards.
OC3 (Significant Technical Contribution)
- Architected and built the company’s end-to-end QA automation platform from scratch (Selenium/Java → Playwright/TypeScript), integrating it with event-driven CI/CD (GitHub Actions, Google Cloud Build, Pub/Sub and Slack reporting). I am the #1 GitHub contributor across both automation repositories.
- Measurable business impact: publisher integration timelines reduced from approximately 129 days (2023) to around 24 days (2025–26), evidenced through Jira and HubSpot data.
- Production quality ownership across the full defect lifecycle (identify → reproduce → track → confirm fix), with more than 1,270 production defects documented since 2022.
Recommendation letters
- CEO — company scale, innovation and commercial impact.
- CTO — technical authorship, engineering leadership and architectural contributions.
- External client (Director of Programmatic at a UK publisher we integrated) — independent validation of the commercial impact of my technical work.
Questions
-
My OC1 centres on a single engineering initiative that I personally identified, defined and drove into an adopted platform capability rather than multiple unrelated innovations. Is one deeply evidenced example generally viewed as stronger than several thinner ones?
-
I currently have around eight evidence documents (out of the maximum ten). Is there any benefit to using all ten slots if the additional evidence would be materially weaker?
-
For MC, is independent recognition through a well-established crowd-testing platform generally viewed as credible external validation, or do assessors typically expect stronger public recognition such as awards, press coverage or conference speaking?
-
Does MC + OC1 + OC3 seem like the right combination for a senior QA automation profile, or would you approach the optional criteria differently?
-
My title is Senior QA Automation Engineer rather than Architect or Engineering Manager. Based on the type of evidence above, does the level of contribution come across clearly enough, or would you expect assessors to place significant weight on the job title itself?
Thanks very much in advance—I really appreciate any feedback.
