Technical Implementation Engineer

London

Super Payments

Super Payments is the only global fintech platform providing 0% processing fees for merchants. Our mission is to use data and AI to make payments free for businesses, so that everyone wins. 

At Super, we are disrupting payments, like Spotify did to music and Robinhood did to trading. We don't make money from transaction fees;  instead, we monetise through value-added services such as lender commissions and FX. Our platform supports multiple payment methods — from traditional cards to direct bank transfers via open banking, as well as Apple Pay, Google Pay, and our own Buy Now Pay Later solution. 

Super has raised $66M from leading investors including Accel, Union Square Ventures and Local Globe (the same investors behind Spotify, Stripe, Monzo) and founded by Samir Desai CBE, co-founder of Funding Circle. 

Already trusted by thousands of businesses and more than 4 million customers, Super is processing at a run rate of £1.5B and growing 4x YOY

Our Values

  • Customer obsessed: We only succeed when our customers do.
  • Move fast: Build, test and improve quickly. Progress matters more than perfection.
  • Own it: Be accountable, solve problems, and make it happen.
  • Be open: Act with honesty and respect. Transparency builds trust.
  • Win together: Collaboration beats ego every time.

The Role:

As a Technical Implementation/Solutions Engineer at Super Payments, you’ll play a key role in helping merchants successfully adopt our payment solutions. You’ll lead the end-to-end technical onboarding process — from guiding API integrations and troubleshooting issues, to ensuring merchants go live smoothly. Acting as the technical bridge between our customers and internal teams, you’ll diagnose problems, recommend best-practice solutions, and deliver an exceptional onboarding experience. This role combines hands-on technical problem-solving with close collaboration across Sales, Product, and Engineering to help merchants get the most out of Super’s platform and power our mission to make payments free for businesses and rewarding for customers.

What You’ll Be Doing:

Technical Onboarding & Implementation

  • Lead the technical onboarding process for new merchants, from initial API integration through to go-live
  • Provide hands-on support with REST API integrations, debugging code issues, and troubleshooting payment flows
  • Guide merchants through plugin installations and configurations across various e-commerce platforms
  • Create and maintain technical documentation, integration guides, and best practice resources

Merchant Support & Problem-Solving

  • Act as the primary technical contact for merchant queries both during and after implementation
  • Diagnose and resolve technical issues, working with internal engineering teams when needed
  • Conduct technical discovery calls to understand merchant requirements and recommend optimal integration approaches
  • Support Account Executives with technical demos and ongoing merchant issues

Cross-functional Collaboration

  • Partner with Account Executives to identify technical blockers and accelerate deal closure
  • Provide feedback to product and engineering teams on merchant pain points, feature requests, and integration challenges
  • Contribute to the evolution of our merchant-facing technical resources and self-service tools
  • Share knowledge across the business, championing technical best practices

We’d love to hear from you if you:

  • 2-5 years of experience in a technical, customer-facing role (Solutions Engineer, Integration Engineer, Technical Account Manager, or similar)
  • Strong understanding of REST APIs, webhooks, SQL and modern integration patterns
  • Hands-on experience with debugging code and troubleshooting technical issues (bonus if you're comfortable reading Node.js, JavaScript, or TypeScript)
  • Experience in payments, fintech, or e-commerce is highly desirable
  • Familiarity with e-commerce platforms (Shopify, WooCommerce, Magento, etc.) is advantageous
  • Excellent communication skills – you can translate complex technical concepts for non-technical audiences
  • A problem-solving mindset with the ability to work independently and navigate ambiguity
  • Experience using tools like Postman, browser developer tools, and API documentation
  • Customer-first mentality with a genuine desire to help merchants succeed
  • Comfortable working in a fast-paced, evolving start-up environment where priorities can shift quickly

*The stated experience and background is a guide and does not preclude applications from candidates with more or less experience, provided the requisite skills can be demonstrated.

Our Benefits - here’s a few and more to come ….

  • Tax advantage Share Options
  • Flexible working model
  • Work from home set up
  • Learning & Development opportunities
  • Contributory Pension Scheme
