## ABOUT KNOT

Knot’s mission is to empower consumers and businesses alike with connected merchant and banking experiences. Knot is like “Plaid for merchant connectivity.” We are building the platform connecting merchants to the many applications that consumers and businesses interact with everyday. Our flagship CardSwitcher https://www.knotapi.com/cardswitcher/ product allows consumers to instantly update & manage their cards on file with online merchant accounts (e.g. Netflix or PayPal). Newer products like TransactionLink https://www.knotapi.com/tx-link/ support the retrieval of item-level transaction data, while Shopping https://www.knotapi.com/agentic-shopping/ enables native purchasing and checkout capabilities for any app. We are building many new products on top of our novel merchant connectivity platform and we hope you choose to come build them with us!

Founded in 2021, Knot was founded by two brothers and Thiel Fellows - Rory and Kieran O’Reilly - and today powers connected online payment experiences for hundreds of thousands of consumers. Companies like American Express, PayPal, OnePay, Current, BILT, Step, and more choose to embed Knot’s SDK in their apps to power best-in-class experiences for their customers.

Knot is proudly backed by a select group of investors, including Nava Ventures, 8VC, American Express, Plaid, and co-founders & CEOs of prominent companies like Twitter, Warby Parker, Allbirds, Casper, Intercom, Deel, Italic, DraftKings, and many more.

## WORKING AT KNOT

We’re a world-class team hailing from all over the globe with the vast majority of the company in engineering roles. We are looking to further solidify our presence in NYC to be at the heart of the financial services ecosystem.

Our team is relentlessly focused on building for our customers and every member of the financial services ecosystem. We take our work seriously and have fun while doing it. Both are equally important.

## WHAT YOU’LL DO

- Own solutions engineering at Knot - full stop.
- Serve as the technical lead during the entire GTM cycle from pre-sales to implementation to post-sales.
- Guide customers through implementation planning, architecture reviews, security evaluations, and integration of Knot’s mobile SDKs and APIs.
- Work with customers directly to debug & troubleshoot their implementations of Knot and engage other teams at Knot to dig further as applicable.
- Identify patterns of customer friction during implementation of Knot's SDK & APIs and implement solutions to rectify those friction points (i.e. documentation, workflow automations, AI-native solutions, etc.).
- Find and design up-sell & cross-sell opportunities and develop demos/POCs to aid in these strategies alongside the GTM team.
- Contribute to technical documentation for customer onboarding & implementation, integration guides, and technical data flow diagrams.
- Build tools and lightweight features where necessary to help customers work with Knot more seamlessly (e.g. workflow automations, small SDK/API features, developer dashboard improvements, etc.).
- Work directly with GTM and product team leads at Knot daily, as well as various engineering teams.

WHAT YOU’LL NEED TO GET THE JOB DONE

- Experience: 2-8 years of experience working at a startup with 1+ year in a customer-facing role.
- Technical fluency: you have an engineering background that allows you to deeply understand & explain complex systems (e.g. SDKs, REST APIs, webhooks, and authentication) and collaborate with engineers both inside & outside the company.
- Intellectual firepower: you are exceptionally smart and can connect many dots to make high quality decisions.
- Resilience under pressure: you don’t panic when things get hard and thrive in a high-stakes environment.
- Relentless drive: you operate with a maniacal intensity and don't slow down at the first (or tenth) obstacle.
- Sharp judgment: you have elite sense for how to help customers at every turn.
- Clued-in on AI: you use multiple AI tools daily to perform your role and play with new tools frequently (e.g. cursor, chatgpt, claude, google AI studio, agent builders, etc.).

## WHAT WE OFFER

- Interesting and challenging work
- Competitive base salary (commensurate with experience) + up to 20% annual bonus + generous early employee equity
- 100% medical, dental, and vision insurance coverage for you and your dependents (U.S.)
- Unlimited PTO
- Parental leave
- Beautiful NYC office in the heart of Flatiron
- Herman Miller Aeron Desk Chair
- Food (snacks, frequent lunches, and often dinner for those working late)

## About Knot

## Company Overview
- **One-liner**: Knot builds the first merchant connectivity platform, enabling cardholders to seamlessly update and manage payment methods on-file across hundreds of online merchants.
- **Entity Type**: Private (Series A)
- **Headquarters**: New York, New York, United States
- **Founded**: 2021
- **Founders**: Rory O’Reilly (CEO) and Kieran O’Reilly (CTO)

## Core Business
- **Primary industry**: Merchant connectivity / Fintech infrastructure
- **Target customers**: B2B – major financial institutions, fintechs, and startups that embed Knot’s SDK to power card-on-file switching and merchant account connectivity.
- **Mission / Purpose**: Bridge the gap between consumers’ online accounts and the apps they use every day – “the first merchant connectivity layer for the internet.”

## Products & Services
- **CardSwitcher™**: A product that seamlessly updates payment methods on-file across the internet when a cardholder receives a new card or switches accounts. (API/SDK)
- **TransactionLink™**: A product that extends the merchant connectivity platform, linking transaction data from merchant accounts into the user’s financial app. (API/SDK)

## Market Standing
- **Valuation / Market Cap**: Not publicly available
- **Key Metric**: **Total Funding**: $13.0M across two rounds (Seed in 2021, Series A in 2024)
- **Notable Investors**: Nava Ventures (led Series A), 8VC, American Express, Plaid, and others.
- **Growth Signals**: Reaches **200M+ consumer lives** through its financial brand partners; team of ~32 people with 80% in engineering; 13 active job postings as of mid-2025; expanding merchant coverage to power experiences for brands like Amazon, Netflix, Airbnb, and DoorDash.

## Competitive Advantages
- **First-mover in merchant account connectivity** – most existing solutions only cover banking data.
- **Easy integration** – fits into existing tech stack with “just a few lines of code” and boasts best-in-class uptime.
- **Strong network effects** – each new merchant connection increases platform value for both card issuers and consumers.
- **Backed by industry incumbents** (American Express, Plaid) gives credibility and distribution channels.

## Strategic Focus
- Scale the merchant connectivity platform by adding more merchants and enabling new use cases beyond card switching.
- Deepen relationships with financial institutions and expand into adjacent products (e.g., transaction enrichment, account linking).
- Continue building a “talent-dense,” in-person engineering team in NYC to maintain velocity and quality.

## Why Work Here
- **Culture**: Small, tight-knit team (40 people) with high autonomy and ownership. Values include “extreme ownership,” “speak the truth,” and “level up.” Problems are approached from first principles.
- **In-person collaboration**: **5 days/week in NYC office** – intentional co-location for speed and culture.
- **Compensation**: Strong base salary, 20% performance bonus, and meaningful equity ownership.
- **Perks**: Stocked snacks, catered lunches, optional dinners, Herman Miller chairs, flexible time off (no accrual), and frequent team meals.
- **Engineering-driven**: 80% of the team is in engineering; “no handoffs, no blame, no excuses” – engineers own code from deployment to performance.
- **Hiring process**: Apply → initial coding/technical interview with tech lead → CTO chat → onsite (system design + cross-functional) → fast offer. “Wildcard” role available for versatile contributors.
