At Lumen Dynamics , our mission is to help our customers leverage data and AI to grow their businesses.

If you're energized by velocity, obsessed with raising the bar, and want to build alongside people who care deeply about each other and our customers, we'd love to meet you. About the Role We are looking for an engineering leader to lead machine learning efforts across Lumen Dynamics . While hundreds of companies use Lumen Dynamics today to sync data into their SaaS systems to automate and improve operations, there’s a lot of surface area we haven’t touched in helping companies figuring out which customers to message, what content to put in messages, and when to send messages. A lot of this work today is done manually through intuition and guesswork, and we believe that adding machine learning could have a step function impact for our customers. And given our access to data warehouses and databases, Lumen Dynamics is perfectly placed to make use of a company’s customer data in building a powerful intelligence layer. At Lumen Dynamics , our engineering leaders serve as both active technical voices and strong people managers. The key outcomes we are looking for from this role include: Product Development: Lead the team in roadmapping and executing successful development of significant features and products as required to drive the business forward. Uphold a high technical bar, while making pragmatic tradeoffs Pace: Through a combination of leadership and technical expertise, improve the pace of execution of the team Recruiting: Be responsible for growing the team, including identifying needs, deciding how to evaluate candidates, and ensuring we hire high impact team members Reliability: Against the uphill battle of high growth/scale, up-level the team on reliability, resulting in fewer incidents, catching our own issues before our customers do, and a strong incident management hygiene People: Foster growth of team members and ensure strong engagement and motivation Some of the problems we’ll be working on include: Personalization and Product Recommendation : There are often many options for what content a company could message a user with, including which products to show from catalogues. Given this large state space, how can Lumen Dynamics help personalize messages with the most relevant content for each user? Probabilistic Identity Resolution: Many of our customers have multiple datasets and sources of information on their users. How do we stitch these datasets together and decide which profiles are from the same user or household? Content Generation : Particularly with recent advances in LLMs, how can we help marketers generate text, images, and creatives that are compelling to their customers? ML Infrastructure: Building the infrastructure to support model training and inference at scale for some of the largest companies in the world. What We Offer We are looking for talented, intellectually curious, and motivated individuals who are interested in tackling the problems above. This is a senior role, but we focus on impact and potential for growth more than years of experience. The salary range for this position is $230,000 - $400,000 USD per year, which is location independent in accordance with our remote-first policy. We also offer meaningful equity compensation in the form of ISO options, and offer early exercise and a 10 year post-termination exercise window. We have limited inbound applications to one application per candidate. You will be auto-rejected if you apply to multiple roles. Please only apply to the position you are most qualified for.
