ROLE OVERVIEW

We are looking for full-stack application developers to focus on building & evolving product features and to grow into ownership of application-level features. This specific role will focus on our third-party integrations (e.g., CRMs, Zapier, Slack) and our integrated applications (i.e., desktop/Electron application and Chrome extension).

As part of our team, you’ll play a critical role in improving customer experiences by scaling our services and contributing to our culture of innovation and continuous improvement. You’ll work closely with our backend, infrastructure, and application engineers, as well as our outstanding customer support team to deliver an unmatched customer experience.

HOW YOU’LL HELP US WIN

Contribute to our collection of highly-scalable services (some stateless, some stateful). Our services run in multiple regions, are engineered to support spiky but predictable workloads, and are deployed via multi-stage rollouts to build confidence in the correctness and efficiency of changes.

REQUIREMENTS

Hard Skills

• Familiarity with our tech stack or equivalents: Ruby/Rails/Sidekiq, Typescript/TSX, MySQL, Redis, Pusher, Electron, GCP/GKE

• Experience in a SaaS or PaaS environment at our scale (currently 100s of millions of async jobs per week)

Soft Skills

• Curiosity-driven and pragmatic with a focus on delivering results

• A generalist mindset with the ability to dive deep into a wide range of challenges

• Resilience, attention to detail, and an ability to grind through complex problems

• Openness to disagreement and commitment to decisions once made

• Strong collaborative skills, with the ability to explain complex insights in an accessible manner to both technical and non-technical audiences

• Independence in managing one’s workload and priorities

WHAT'S IN IT FOR YOU

• The opportunity to shape the foundational software services of a growing company

• A role that balances innovation and incremental improvement

• A dynamic and collaborative engineering team

• Competitive compensation and benefits

• A supportive environment that encourages innovation and personal growth

WHY YOU SHOULD JOIN US

• Opportunity for impact. We’re established enough to ship instead of fighting fires and early enough that your work will have a real impact.

• Startup experience. You’ll work closely with our CEO, a 2X Founder/CEO with a background in computer science and product design.

• We embrace being fully remote. We schedule meetings sparingly and instead heavily use async comms (Slack, Notion, Loom)

ABOUT THE INTERVIEW

• No live coding. We have no idea who thought writing code on whiteboards was a good idea but we hate it. We’re much more interested in what you’ve done and learned.

• You’ll meet the entire team. We think it’s important that you get to meet everyone you’ll be working with.

• No bullshit. Ask us anything you like. We’ve never understood why companies pretend they’re something that they’re not in the hiring process - you’re going to find out eventually so we’d rather you know who we are up front so we can both make sure this is a good fit for all involved.

• Quick turnaround time. We know you have lots of options so we move fast usually in less than a week from start to finish.
