Markforged is liberating designers and engineers from the long lead times and high costs of traditional manufacturing. We build cutting-edge next generation cloud connected industrial 3D printers that produce parts 50x faster that are 23x stronger and 20x lower-cost. NASA, Google, Ford, Amazon, Siemens and thousands of companies in 50 countries use Markforged printers to produce same-day prototypes and stronger end-use parts than ever before.

Our software technologies and tools empower our customers to configure print-ready parts, visualize part geometry in 3D, and push to IoT-connected printers for printing. As part of the Software Engineering team, you would be helping to lead the scaling and growth of our 3D printing platform involving end-customer applications and IoT services.

As a Backend Software Engineer you will be responsible for building out and scaling the systems that power our 3D printing platform. We move at a breakneck pace but refuse to compromise on quality. We believe in “doing it right the first time” and investing in code quality, testing, tooling and infrastructure. Your ideas will directly influence the company's future. You will do interdisciplinary work on physical systems and learn from best-of-the-best engineers across MatSci, Mech-E, EE, and Software.

In this role you will:

  • Design, build, and maintain APIs, services, and systems across Markforged's engineering teams
  • Debug production issues across services and multiple levels of the stack
  • Work with engineers across the company to build new features at large-scale
  • Improve engineering standards, tooling, and processes
  • Plan for the growth of Markforged's infrastructure
  • Build a great customer experience for people using your infrastructure
  • Build infrastructure that’s specific to our APIs, e.g. serving webhooks with low latency
  • Serve as on-call for our API, e.g. responding to API abuse impacting our databases

What we look for:

  • Hold yourself and others to a high bar when working with production systems
  • Take pride in working on projects to successful completion involving a wide variety of technologies and systems.
  • Enjoy and have experience building APIs
  • Thrive in a collaborative environment involving different stakeholders and subject matter experts
  • Think about systems — their edge cases, failure modes, and lifecycles
  • Know your way around a Unix shell
  • Are able to write and review high quality code in multiple programming languages (e.g. Javascript, Coffeescript, Python, C)
  • Can design, build and operate services that are the foundation of Markforged's cloud printing software
  • Can design and implement tooling and automation for clustering, scaling, monitoring and alerting
  • Focus on eliminating risks and build reliable, scalable and performant systems
  • Are looking for an environment where you and your teammates empower one another to become the best versions of yourselves
  • Will show empathy towards developers, e.g. when making design decisions and breaking changes
  • Are well rounded throughout the stack, capable of building infrastructure and product code (UI not necessary)
  • Derive job satisfaction from abstracting and refactoring
  • 3-5 years experience building and shipping high quality code
  • Strong CS fundamentals
  • Bachelors degree in Computer Science, or equivalent
  • Experience building APIs, Services and Scaling Systems
  • Proficiency in writing Node applications and scaling them to support thousands of users and millions of events
  • Knowledge of database internal implementation, particularly SQL planning and optimization
  • Knowledge of performance optimization, parallelization, and distributed systems
  • Experience with authentication and authorization schemes, building your own solutions and/or leveraging SSO.
  • Significant Experience with Schema Design and Query Optimization
  • Excellent command of Javascript or Coffeescript
  • Experience with Go, Rust or Scala (we're not currently using these but bonus points for experience)

It’s not expected that any single candidate would have expertise across all of these areas. For instance, we have wonderful team members who are really focused on their customers’ needs and building amazing user experiences, but didn’t come in with as much systems knowledge.
