OPEN POSITION: Engineering

Senior Frontend Software Engineer


About Prefect:

Are you looking for an incredible opportunity to work with a high-growth SaaS company? Our workflow orchestration platform bridges the gap between data engineers and data scientists, allowing them to do what they do best. We are looking for enthusiastic new additions to our team who are excited by the question “what will you build?”

Role Summary:

As a Senior Frontend Software Engineer at Prefect, you will work on and lead projects that directly impact our users and customers, allowing them to gain insight into their workflows in real time.  Our UI is the main interface for users, and as such needs to be highly optimized and performant, designed with the ability to handle and visualize millions of data points simultaneously.

You will coordinate with internal stakeholders, including our CTO and CEO, on new features and help Prefect execute our company’s product roadmap. You will proactively identify opportunities for improvement, build consensus, track risks and dependencies, and lead projects to completion with a positive attitude. You will be a mentor and provide leadership to other members of the engineering team.

You will be an enthusiastic champion for user empathy across all our products. We expect our engineers to be product focused and enthusiastic to take on new challenges and drive our product and culture forward.


  • You will be responsible for working closely with the UI team and the engineering organization more broadly to deliver a highly available, best-in-class web application for interfacing with our Core, Cloud, and Server products

  • You will drive our open source projects and engage with our community, and constantly seek to advance our internal user empathy by championing use cases

  • You will lead a high-performing and winning culture and foster a collaborative working environment with other members of the engineering team

  • You are a self-starter: you will not hesitate in taking ownership of your ideas and advocating for them

  • Extreme attention to detail - Prefect requires thinking through extreme edge cases without losing sight of providing a simple user experience

Qualifications (you must have):

  • 5+ years experience working with JavaScript and JavaScript frameworks (specifically Vue)

  • Knowledge of building scalable, modular user interfaces

  • Familiarity with GraphQL APIs

  • Genuine and uncompromising user empathy in design and implementation

  • Experience delivering projects from inception to production

About you (we’d like you to have):

  • Experience with Python

  • Deep knowledge of GraphQL and GraphQL servers

  • Experience with visualizing complex data (bonus if you’ve used D3js or a similar visualization library!)

  • Enthusiasm and experience building clean and beautiful interfaces

  • Experience contributing to open source projects

  • Excellent judgement and analytical ability

  • Experience in a start-up or high-growth environment

  • Experience with data engineering and data science workflows

  • … and an understanding of how and when to “break the mold” when the best practice for Prefect deviates from an industry standard
