What Skills Should You Bring?

6+ years with backend JavaScript and TypeScript 6+ years with Go and React Knowledge of distributed systems and cloud platforms Experience with AWS / MongoDB + Postgres

You need to be comfortable working on full-stack web applications. You can change UIs, APIs, database schemas, or deployment pipelines as needed. Ideally, you've worked on and led large system migrations. Preferably, you’ve experienced one migration that’s gone well (so you recognize success) but also one that was challenging (so you've learned from mistakes).

What Will You Work On?

Our team owns multiple new products that will be part of our assessments platform. We have initial projects underway but by no means is the plan fully defined. As a senior-level developer, you have opinions on design tradeoffs in this space and can articulate them in productive debates with the team, weighing short vs. long-term impact. You'll be the glue between leaders in Product and the rest of the development team. You'll work directly with product managers to prioritize features and improvements. It's essential that your technical perspective informs what's possible. Your opinions are as strong as the data you have to defend them.

Along the way, you will help guide our quality improvements. We expect you to be familiar with techniques and processes such as pair programming, code reviews, automated testing (unit/integration/end-to-end), feature flagging, monitoring, and alarming. We expect that you will mentor developers to adopt the practices that meet your quality expectations. We also expect that you can articulate the limits of these approaches and know what mix to use for any given problem.

As a Senior Developer it's crucial that you have strong written and verbal communication skills. You should have no problem discussing issues publicly on Slack, ensuring your reasoning is available to anyone when needed. Your project plans, status updates, high-level task summaries should be clear and easy reads. You will contribute all manner of system and architecture diagrams to the wiki to ensure the whole team is aligned with your technical vision. You also know when it’s time to hop on a video call to hash something out.

You're also adept at providing feedback. You can gauge where a developer is at and provide them with specific, actionable feedback to improve. Your commits and pull requests will set the high standard for other developers to follow. Your review comments will be written with empathy and tact where code quality could be improved to meet your professional standards.

Interview Process

Here are the steps you can expect:

Conversation with Recruiter.

Have a 30-minute phone call during which you get to share your professional journey, career interests and assess initial skills. Meet the Manager.

Spend 45 minutes on a video call with your potential future manager. Discuss your relevant technical work experiences and learn in-depth about the day-to-day of the team and role. Asynchronous Code Review.

A brief take-home project that offers you the opportunity to showcase your ability to give feedback and mentor other team members. Meet the Team & Showcase Your Technical Abilities.

Meet with 3 more team members, a blend of technical and non-technical people, leaders, future peers and collaborators. You’ll meet 1-1 in a remote setting, go through live coding and system design exercises.
