We are looking for experienced Mid-level (Full Stack, Backend, Frontend) Engineers passionate about building an excellent user experience up and down the layers of an application.

We aim for our Engineering team to be a place that Mid-level Engineers can push our quick-growing startup forward, and grow into future Senior Engineers and Engineering leaders. The significant projects and initiatives available to our Mid-level Engineers provide opportunities to expand experience, ownership, and business value.

Our greatest strength is our people and we'd love for you to be one of them!

Responsibilities:
  • Collaborate closely with the development team, including UX designers, product managers, and other Engineers, to implement solutions that meet business needs and provide the best user experience
  • Work with stakeholders to design, build, test, and release new features for our platform
  • Write clean, efficient, and maintainable code. Break down code contributions into reviewable, shippable chunks
  • Contribute to the Engineering design process by bringing forward tradeoffs and opinions
  • Identify opportunities to reduce technical debt and implement changes to improve developer experience and team velocity
  • Participate independently in on-call rotation and coordinate incident response
What You'll Bring:
  • Minimum of 2 years experience as a Software Engineer (excluding internships or coop experiences) with a focus on full stack development
  • Strong proficiency in at least one backend application framework such as Django or Flask and experience with frontend technologies such as React, Angular, or Vue.js
  • Proven experience building, deploying and maintaining scalable web applications, with knowledge of database design and management
  • Knowledge of RESTful API design and integration
  • Experience working with cloud infrastructure and containerization technologies such as AWS, Docker, and Kubernetes is preferred
  • Passion for learning new technologies and keeping up with industry trends
  • Ability to collaborate with cross-functional teams, including UX designers, product managers, and other Engineers
  • Strong communication skills and ability to articulate technical concepts to non-technical stakeholders
