The Onyx Research Data Platform organization represents a major investment by GSK R&D and Digital & Tech, designed to deliver a step-change in our ability to leverage data, knowledge, and prediction to find new medicines. 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, increasing productivity and reducing time spent on “data mechanics”
  • Providing best-in-class AI/ML and data analysis environments to accelerate our predictive capabilities and attract top-tier talent
  • Aggressively engineering our data at scale to unlock the value of our combined data assets and predictions in real-time

A Senior Engineer is a leading technical contributor who can consistently take a poorly defined business or technical problem, work it to a well-defined problem/specification, and execute on it at a high level. They have a strong focus on metrics, both for the impact of their work and for its inner workings/operations. They are a model for the team on best practices for software development in general (and their specialization in particular), including code quality, documentation, DevOps practices, and testing, and consistently mentor junior members of the team. They ensure the robustness of our services and serve as an escalation point in the operation of existing services, pipelines, and workflows.

A Senior Engineer should be deeply familiar with the tools of their specialization and of their customers and engaged with the open source community surrounding them – potentially, even to the level of contributing pull requests.

  • Produces well-engineered software, including appropriate automated test suites, technical documentation, and operational strategy.
  • Diverse problem solver who surfaces opportunities to reuse modular code and develop microservices to drive efficiencies.
  • Provides input into the roadmaps of teams representing upstream dependencies to help improve the overall program of work.
  • Ensure consistent application of platform abstractions to ensure quality and consistency with respect to logging and lineage.
  • Fully versed in coding best practices and ways of working and participates in code reviews and partnering to improve the team’s standards.
  • Adhere to QMS framework and CI/CD best practices and helps to guide improvements to them that improve ways of working.
  • Stay updated on emerging API technologies, trends, and best practices. Identify areas for improvement in API architecture, performance, and development. Mentor and guide junior engineers, supporting their growth.
