Command Line Design Engineer - Rust

North America
Posted on Friday, May 26, 2023
In this role, you will be responsible for designing and developing Ockam's Open Source Command Line.
Ockam crates implement a collection of messaging and cryptographic protocols that provide end-to-end application layer trust in data. We believe that, in order to have a realistically manageable vulnerability surface, all modern applications need end-to-end guarantees of data integrity and authenticity. The only way to build secure and private applications is to remove unnecessary implicit trust in network boundaries, intermediaries and infrastructure.
As a Command Line Design Engineer, you will play a crucial role in developing and improving our command line interface (CLI) tools, ensuring they deliver a seamless and user-friendly experience. You will need to combine your expertise in Rust programming with a strong focus on user experience (UX) design to create efficient and intuitive command line interfaces that meet the needs of our customers.
The Ockam team is passionate about making powerful cryptographic protocols simple and safe for application developers. In this role you will collaborate across the Ockam Engineering team to deliver a safe, secure, stable, well-documented, easy to use, 100% open source Rust command line.


  • Strong proficiency in Rust programming language, with a proven track record of developing robust and efficient command line applications.
  • Experience with user experience (UX) design principles and methodologies, and a demonstrated ability to create intuitive and user-friendly interfaces.
  • Customer empathy and the ability to understand user needs and translate them into effective design solutions.
  • Excellent problem-solving and debugging skills, with a keen attention to detail.
  • Building components in complex code bases.
  • Modern build systems, CI/CD pipelines and DevOps.
  • Consuming and contributing to open source codebases.
  • Git and GitHub's workflow.
  • Strong communication and collaboration skills, with the ability to work effectively in a team environment.

  • Distributed systems, Actor based concurrent systems and Messaging Protocols.
  • Provisioning and operating basic cloud services in AWS, Azure or Google Cloud.
  • Familiarity with multiple programming languages
