We are a full‑stack shop consisting of product and portfolio leadership, data engineering, infrastructure and DevOps, data / metadata / knowledge platforms, and AI/ML and analysis platforms, all geared toward building a next‑generation data experience for GSK's scientists, engineers, and decision‑makers, providing best‑in‑class AI/ML and data analysis environments, aggressively engineering our data at scale, and implementing scientific technology products.
Role Summary
The Application Engineer II is a solid individual contributor at Onyx. You will design, build, deploy, and operate data‑driven applications that serve our scientific community, turning loosely defined requirements into high‑quality features and production‑grade experiences. You will confidently break down small to medium‑sized engineering problems, lead implementation end‑to‑end, and collaborate across product, data, and platform teams.
Responsibilities
* Design, implement, test, document, and deploy full‑stack, data‑driven cloud applications; own features end‑to‑end from MVP to production‑grade experiences.
* Develop and operate reliable APIs and services (REST/GraphQL/gRPC) with strong authentication/authorization, observability, and performance characteristics.
* Operate and support applications in production, including participation in on‑call; create and maintain runbooks/playbooks; lead resolution of bugs and incidents.
* Define, measure, and monitor key product and operational metrics (e.g., performance, reliability, cost); iterate to improve them through data‑informed decisions.
* Proactively improve test coverage, CI/CD pipelines, and release safety; champion automation and high‑quality software engineering practices.
* Identify and address gaps in observability, alerting, and monitoring; implement metrics, logs, traces, and SLOs that enable robust operations.
* Collaborate with product to refine user requirements, break down work, plan milestones, and communicate progress and risks to stakeholders.
* Contribute to system design within the team; propose pragmatic refactoring to reduce complexity and technical debt while balancing short‑ and long‑term needs.
* Produce clear documentation, proposals, and technical guides so others can understand, use, and build upon your work; actively participate in code reviews.
* Help onboard and mentor engineers in your team; share best practices and contribute to a culture of innovation, transparency, and trust with a patient‑first mentality.
Qualifications and Skills
* Bachelor's degree in a communication related field or in Computer Science, together with significant demonstrable engagement experience within IT or Pharma.

* Ability to manage time effectively without supervision and to organize, prioritize and deliver tasks and projects with a sense of urgency.
* Deep knowledge and use of at least one common web backend language (e.g., Python, Scala, Java, JavaScript (Node.js)) and associated toolchains for documentation, testing, and operations.
* Experience developing and deploying applications in a cloud environment (Google Cloud preferred, AWS or Azure).
* Strong experience with modern software development tools and ways of working (e.g., Git/GitHub, DevOps tools, metrics/monitoring).
* Proficiency in front‑end technologies: JavaScript, TypeScript, React.js, Angular.js or similar.
* API development using standards such as REST/GraphQL/gRPC.
* Experience with an open‑source web framework (Python, Java, Scala or similar).
* Experience with Authentication & Authorization mechanisms such as OAuth2.
* Experience with CI/CD implementations using Git and a common CI/CD stack.
* Experience in agile software development and common environments such as Jira and Confluence.
Preferred Qualifications and Skills
* Master's degree or higher.
* Significant experience delivering cross‑functional projects.
* Experience embedding operation excellence culture within teams.
* Knowledge of database modelling, database concepts and SQL.
