About Knock
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) Series A startup of 20+ 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 Craft Ventures, 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 this role
We’re looking for a Developer Success Engineer in the UK or Ireland to come join our growing team and help our customers be successful in using Knock to power their cross-channel notifications.
Our users are technical. Most of them are developers. You will be responsible for meeting them where they are, building a relationship, and helping them get the most out of Knock.
In this role, you’ll be on the front line, working with Knock customers throughout their lifecycle, from their initial trial of the product to implementation to expansion.
What you’ll be doing in this role
As a Developer Success Engineer, you’ll wear multiple hats depending on what the customer needs. Here are the types of work you should be comfortable with:
Owning the technical relationship with our largest customers from initial implementation through launch and ongoing optimization. This could mean leading bi-weekly check-ins, consulting on implementation plans, creating solution documents, or answering technical questions in Slack. You’ll be the first person they reach out to when something isn’t working as expected.
Jumping into code with customers. You’ll review their implementation, debug integration issues in their repos, write sample code to demonstrate patterns, and escalate issues internally when necessary.
Triaging inbound questions from self-serve customers on Slack and email, often requiring you to dig into our codebase, reproduce issues locally, or query production databases to understand what’s happening.
Identifying and fixing friction in the developer experience. If documentation is missing or unclear, you write it. If customers keep hitting the same edge case, you file bugs and feature requests in Linear and advocate for changes with the product and engineering team.
Creating technical content that demonstrates how to use Knock effectively — sample apps, integration guides, video walkthroughs, and example code that becomes the reference for how things should be done.
Supporting sales conversations with technical prospects, as needed. This includes answering technical questions during calls and helping prospects run successful proof of concepts.
What we’re looking for in this role
A love for solving open-ended problems for customers and endless curiosity.
2+ years of experience as a developer success engineer or adjacent role, ideally with prior experience working at a developer tools company and working directly with customers.
Recent experience at an early-stage startup.
A strong technical generalist who is comfortable talking about technical concepts from both a product feature and an architecture perspective.
Prior experience debugging API integrations.
Prior development experience with one or more languages, such as JavaScript, Ruby, Python, Go, Java, or similar.
Excellent writing skills.
Located in UK/Ireland
Note: you can be a great fit even if you don’t perfectly match what’s described above. 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!
A note on AI at Knock
The Developer Success team uses AI to streamline day-to-day work and provide Knock’s customers with the best support possible. We will encourage you to use these tools and contribute to our shared AI tooling, like adding to our Claude skills repository or building new workflows that help the team. We’re proud of the human touch we offer and expect you to bring your own perspective and experience to customer interactions and internal discussions.
AI use is acceptable throughout the interview process unless otherwise noted. We want to see how you think and work. Show us your judgment, technical reasoning, and communication style, not just polished outputs.
