Staff Backend Software Engineer - Carbon, Inc.

At Carbon, our mission goes beyond 3D printing.  We are enabling creators everywhere to make what the world needs, right now.  Our company is built on the idea that diverse fields of study must come together to solve intractable problems. We have grand ambitions to create technology that will influence industry around the world. You will be joining a diverse team with a vibrant culture, where team success is as important as celebrating individual contributions.

Help us change the world and we will help you change yours.

Working at the intersection of hardware, software, and molecular science, Carbon delivers on the promise of 3D printing by helping commercial customers move beyond prototyping to produce real-world parts. Every one of those parts depends on a printer in a customer's factory staying online, up to date, and in perfect two-way conversation with our cloud.

We are looking for a Staff Backend Engineer to own the services that live on that seam between our cloud and our global fleet of printers. You will design and build the backend systems that provision, update, and communicate with printers in the field, own major initiatives end to end, and set a high bar for how we build Linux-based systems that have to be right the first time, on hardware we can not physically touch.

You will:

• Own the Services Behind the Fleet: Be a core owner of the backend services that manage printer identity, connectivity, provisioning, updates, and telemetry. You will keep them resilient and highly available as our fleet grows, and drive the design of new services that unlock new device capabilities.
• Build the Linux Layer Underneath: Design and improve how our printers come up, install, and update, from initial bring-up through in-field OS updates and rollbacks. You will bring deep Linux fundamentals to bear on real problems in the field, where "reinstall the machine" is not an option.
• Own the Network Between Cloud and Printer: Design the protocols, connections, and failure modes that keep a printer talking to our cloud reliably from anywhere in the world, including flaky networks, restrictive corporate firewalls, and long offline periods. You will care about latency, back-pressure, retries, and the boring reliability details that make the whole system feel solid.
• Drive Major Initiatives End-to-End: Take full ownership of substantial backend initiatives, from design through production rollout on real printers. You will influence architectural decisions and help shape the long-term direction of the cloud-to-device platform.
• Own Reliability Alongside the Team: Participate in on-call for the services you own, drive incident response and postmortems, and turn recurring pain into permanent fixes. You will help other teams operate the services that depend on yours.
