Senior Platform engineer

Location: Herndon, VA (Remote) Type: Full-time Who You Are We're looking for a Platform Engineer to help build and maintain the infrastructure that empowers our engineering teams to ship software reliably at scale. This is a role for someone who is equally comfortable diving deep into technical problems and stepping back to lead, mentor, and influence across teams. You'll play a central role in shaping the direction of our platform; not just by writing great code and building robust systems, but by setting technical standards, guiding architectural decisions, and helping grow the engineers around you. Being successful starts with being able to thrive in environments undergoing maturity transformation; embracing ambiguity, driving process improvements, and turning ad hoc practices into scalable, repeatable engineering standards. Understanding what it takes to build platforms not just for today's demands, but for the next order of scale, designing systems and team practices with future growth in mind.
