Senior Backend Software Engineer Application Development Jobs

EMPLOYER IS A CONTRACTOR FOR THE U.S. GOVERNMENT. THIS POSITION WILL REQUIRE AN ACTIVE SECRET CLEARANCE TO APPLY. Staff Platform Engineer Defense Unicorns is seeking a Senior Platform Engineer to join our team. This role is responsible for designing, building, and owning the runtime production environment that bridges applications (custom development, COTS, and OSS) to the underlying platform. You will drive platform architecture decisions, set engineering standards, and serve as the technical anchor between application teams and platform teams. This is a hands-on technical leadership role. You will own platform strategy and implementation end-to-end: defining technical roadmaps, solving complex problems that span multiple domains, driving cross-team delivery efficiency, and mentoring engineers across the team. We are looking for someone who builds and owns platforms, not someone who operates within infrastructure others have designed.

We believe that the way people interact with their finances will drastically improve in the next few years. We’re dedicated to empowering this transformation by building the tools and experiences that thousands of developers use to create their own products. Plaid powers the tools millions of people rely on to live a healthier financial life. We work with thousands of companies like Venmo, SoFi, several of the Fortune 500, and many of the largest banks to make it easy for people to connect their financial accounts to the apps and services they want to use. Plaid’s network covers 12,000 financial institutions across the US, Canada, UK and Europe. Founded in 2013, the company is headquartered in San Francisco with offices in New York, Seattle, Washington D.C., Raleigh, London, and Amsterdam. Team: Plaid is becoming an AI-first company, and AI Tooling is being built from the ground up to extend AI-native tooling to non-engineers at Plaid. Tools built for engineers assume things non-engineers don't have: local toolchains, monorepos, engineer credentials, PR-based workflows. That mismatch means Ops, Support, and other teams can't easily inherit what we build for engineering. They need their own path and we're building that path. Role: As a Senior Software Engineer on AI Tooling, you will build and operate internal systems that empower non engineering teams to automate their workflows with AI. You will own the product and platform layer for internal tools, including the constraints and infrastructure that keep those tools safe and maintainable. There's no existing playbook for this at Plaid. You will define what the right non-eng AI surface looks like, ship its first durable versions, and partner closely with internal users to make sure it solves real problems. You will act as the engineering point of contact embedded with non-engineering teams, running discovery and translating their operational needs into shipped software. What you build here becomes how non-engineering
