Platform Engineer in Cambridge

The role Healx is hiring a motivated Platform Engineer to build cloud infrastructure and develop production pipelines that enable our AI drug discovery process. You will bridge the gap between infrastructure and scientific software, designing, building and supporting cloud infrastructure while collaborating with bioinformaticians, machine learning engineers and data scientists to implement data pipelines. You will join a small, agile engineering team where individuals take ownership of tasks, innovate quickly and collaborate extensively through pair programming. Working closely with technical members of data and digital science teams you will clearly see the impact your work has on pioneering the next generation of AI drug discovery and finding treatments for rare disease patients in need.

We encourage you to provide a covering letter to explain why you think you would be successful in this role.

Key Responsibilities

• Design, build, maintain and improve cloud infrastructure in AWS (and some GCP) to enable AI drug discovery workflows.
• Follow infrastructure as code (IaC) and CI/CD principles to build maintainable infrastructure using Terraform and CircleCI.
• Take advantage of latest AWS tools and apply best practices across our cloud estate to ensure security, availability and observability.
• Work closely with technical users across the company to understand and support their computational needs.
• In collaboration with data scientists write code to build, test and automate production pipelines in tools such as Nextflow, Airflow, MLflow and KNIME.
• Embrace the use of AI coding tools and agents to accelerate delivery while retaining responsibility for system design, implementation and testing of code.

You will know you are successful when

• You have strong ownership of parts of our cloud infrastructure, familiarity with our Terraform codebase and are shipping regular improvements.
• Infrastructure you've designed and deployed is supporting drug discovery pipelines.
• You have taken ownership of security, cost management and observability in our cloud estate.
• Computational workflows are in production that you've built in Nextflow, Airflow, MLflow or similar in collaboration with digital scientists.
• You have shipped maintainable code to enable lambda functions, automation scripts and internal tools in several of our Python repositories.

What We're Looking For

• We're looking for a mid level engineer with solid hands on experience building cloud infrastructure in a commercial environment who is keen to apply what they already know and learn new skills.
• You are highly collaborative and driven to solve problems that help others and drive the Healx mission.
• You have hands-on experience (typically around 2+ years) working with a cloud platform, ideally AWS, and are excited about building cloud infrastructure following best practices.
• You are a proponent and practitioner of infrastructure as code principles, ideally with experience in Terraform, and have experience building, maintaining and scaling CI/CD pipelines.
• Solid experience writing maintainable and well tested code following best practices in at least one language (we use mainly Python and some Go).
• An automation mindset, ideally with experience building production workflows in tools like Airflow.
