Sr Site Reliability Engineer

About the job

Our team builds the cloud infrastructure that powers LN’s Data Science and Machine Learning Operations capability. Designing and building a robust data science/MLOps platform is a huge challenge as our organization transitions from on-prem to cloud infrastructure. This role will take point in continuing to build and improve our cloud analytics platform leveraging new cloud capabilities while optimizing costs. It will focus on building Cloud-Native/Self-Service implementations so we can offer seamless access and transparency to disparate data assets across the organization. You will be a critical member of a collaborative and forward-thinking team working with a diverse range of technologies, able to enjoy an amiable and supportive environment, and benefit from our investment in team skill-building and cross-training, where we leverage each other’s strengths. This is a senior position. The successful candidate is a self-starter who assesses the situation, collaboratively develops a solution, and takes the initiative to improve performance, cost, and reliability at each opportunity. You will be supported by a management team that values your contribution, your ideas, and supports you in solving problems to root-cause rather than applying band-aids or superficial fixes. If you are a doer, a thinker, and an initiator that wants a climate where they can truly pursue excellence in themselves and their work, you could be the person we’ve been looking for.
