We are building the fastest, most powerful customer support platform for the next generation of B2B companies. Some of the world’s most forward-thinking companies, like Stytch, Sanity, and Fly.io, rely on Plain to consolidate all the channels where they speak with customers, collaborate with their teams, and speed up their workflow with our lightning-fast UI.
We’re looking for a Senior Platform Engineer to join our team and help us define the next phase of support tooling

WHAT YOU’LL DO

You’ll help define and execute the future of our platform architecture, working closely with other engineers to ensure Plain remains fast, reliable, and secure as we scale.

You will:

• Lead key infrastructure initiatives. This includes projects like building support for multi-region deployments, overhauling our pre-production and test environments, and tackling performance across the stack.
• Make the whole team faster. Your job is to build infrastructure that empowers other engineers - not just maintain what’s there. You’ll be improving deployment speed, reducing test flakiness, and enabling faster iteration across the board.
• Shape our platform direction. You’ll define how we evolve our use of AWS, set patterns and practices for managing infrastructure-as-code, and help us balance technical ambition with pragmatic delivery.
• Solve problems that matter. You won’t be chasing theoretical scale. You’ll be making high-leverage, business-impactful decisions that help us deliver value to customers faster and more safely.

THIS WON’T BE THE RIGHT ROLE IF YOU…

• Are uncomfortable with ambiguity. We have some really exciting traction but are still at an early stage and are constantly learning and trying new things as our company grows.
• Find learning about new technologies a key motivation for coming to work. We invest in what makes us productive but will prefer the known option to the experimental and novel. Postgres is great.
• Are primarily motivated by solving hyperscale, distributed systems problems. Our infra challenges are real, but the primary lens is productivity and impact—not complexity for complexity’s sake.
• Are looking to manage others. This is a senior IC role—we’re looking for someone who wants to stay close to the work.
• Expect all the perks of a big company. We’re a Series A startup—competitive for our stage, but definitely not cushy.
