💻 Product Engineer (full-stack)

Knock is on a mission to help products communicate with their users in a more thoughtful way. Building product notifications in-house takes months, often leading to poor user experiences. We believe that—when done right—product notifications help users find value in the products they use every day. That’s why we built Knock.

We're a remote-first (with a NYC base) seed stage startup of 11 employees that believe in the power of great software. We're APIs all the way down at Knock—Stripe for payments, Algolia for search, WorkOS for SSO. We're excited to add Knock to that list and to push forward the API-first movement. If you are, too, come join us and let's build something great together.

We’re backed by top investors and operators including Afore Capital, Preface Ventures, Worklife Capital, Guillermo Rauch (CEO/Founder @ Vercel), Scott Belsky (CPO @ Adobe), Adam Gross (CEO @ Heroku), John Kodumal (CTO @ LaunchDarkly), Nate Stewart (CPO @ Cockroach Labs), Charley Ma, and Zach Holman, to name a few.

About the role

We're looking for a full-stack engineer to join our small but growing team. Full-stack engineers at Knock work on product features end-to-end, from our customer facing APIs, through to our Next.js powered workflow builder. We’re an engineer led team, with a strong belief in shipping high-quality product at a fast pace. This is a role where you will have a high degree of ownership and autonomy over the features you design, build, and support.

We care deeply about building a team and culture that is inclusive and equitable for people of all backgrounds and experiences, and believe firmly that the best teams are diverse. We particularly encourage people from underrepresented communities to apply.

Last thing: you can be a great fit even if you don't perfectly match what's described below. We know there's a lot we don't know and haven't thought of yet, and we're looking for teammates that can tell us what those things are. If that's you, don't hesitate to apply and tell us about yourself!

What you'll be doing in this role

• Work on features across the Knock product, from our Dashboard that supports our customers, through our CLI and API to enable developer workflows
• Own product features from design through to shipped documentation, working closely with our founders and experienced team to shape a feature and ship it to our growing customer base
• Contribute to our open-source SDKs and libraries that our customers use to integrate Knock into their applications
• Talk to and support our customers in bringing to life best-in-class notification systems. We are a team that believes in everyone having direct contact with the customer and bringing that voice to the decisions we make every day

What we’re looking for in this role

• You have 3+ years of experience building full-stack web applications, with strong fundamentals with JavaScript or (ideally) Typescript and a background in writing React
• You care deeply about building elegant systems that are delightful to interact with on every level, from API design, to documentation, and the user interfaces
• You're interested in building sharp tools that solve problems that you and countless other engineers and product teams face on a day-to-day basis
• You like the idea of joining an early-stage team where you can play a meaningful part in shaping the direction of the company, product, and culture
• You might have some prior experience writing Elixir, but this a nice-to-have and we’re more than happy to support you in learning the language

Our stack

Our backend services are primarily written in Elixir (which runs on the Erlang VM), with some Rust as well. We build our front-end using Next.js in Typescript, powered by GraphQL. Our code runs in AWS on EKS using a mixture of Postgres, Redis, and MongoDB for data storage. All our infrastructure is written in Terraform and continuously deployed via Terraform Cloud.
