Implementation Engineer

We believe that the way people interact with their finances will drastically improve in the next few years. We’re dedicated to empowering this transformation by building the tools and experiences that thousands of developers use to create their own products. Plaid powers the tools millions of people rely on to live a healthier financial life. We work with thousands of companies like Venmo, SoFi, several of the Fortune 500, and many of the largest banks to make it easy for people to connect their financial accounts to the apps and services they want to use. Plaid’s network covers 12,000 financial institutions across the US, Canada, UK and Europe. Founded in 2013, the company is headquartered in San Francisco with offices in New York, Seattle, Washington D.C., Raleigh, London, and Amsterdam.

Client Engineering is the technical arm of Plaid’s European GTM team. We own our customers’ technical outcomes: designing the right solution, getting it built and live, and keeping it healthy as they grow. We work with the most technically forward companies in European financial services – fintechs, lenders, and payments and wealth platforms – helping them build on payment initiation, account data, verification, and underwriting across UK Open Banking and PSD2.

As an Implementation Engineer for Plaid Europe, you’ll own customer integrations from the moment a contract is signed to the moment they’re live in production and growing. You’ll write the integration plan, run the kickoff, debug alongside the customer’s engineers, validate their sandbox implementation, and see them through go-live, keeping their Account Manager up to date with notes that make the relationship easy to continue. You’ll do the same for existing customers adding a new product, use case, or market. You’ll also build the resources that make the next integration faster – the checklists, the common pitfalls, and the answers to the questions every customer asks – because this team is small and its leverage comes from what gets written down.

• Own a portfolio of customer integrations from signature to production launch, including plans, milestones, and exit criteria.
• Run scheduled implementation support for standard integrations, as well as one-off debugging engagements for customers who need a targeted fix.
• Lead technical onboarding for existing customers adopting a new Plaid product, use case, or market.
• Debug integration issues hands-on with customer engineers across API, SDK, OAuth redirect, and webhook behaviour.
• Validate sandbox implementations and run go-live readiness checks.
• Use Plaid’s own data to proactively diagnose integration and conversion problems.
• Produce written handovers to Account Management and maintain the team’s reusable implementation resources.
• Escalate recurring integration failures to Product and Engineering as clear patterns, backed by evidence.

• 4+ years in a customer-facing technical role, such as implementation, integration, solutions, or technical account management, ideally at an API platform.
• Hands-on experience with REST APIs, OAuth, webhooks, JSON, and web and mobile SDKs.
• Comfort working in Postman or curl and reading API documentation critically.
• Experience with SQL or other data querying tools.
• A track record of owning technical projects end to end, with real deadlines and direct relationships with customer engineers.
• Clear written communication skills, including plans, handovers, and customer updates.
• Comfort working independently in a small regional team alongside a globally distributed function.

• Knowledge of open banking, including UK Open Banking, PSD2/PSD3, AIS/PIS, and VRP.
• Domain depth in payments, identity verification, or credit and underwriting.
• A formal technical background or prior software engineering experience.
• Experience with mobile integrations.
• Fluency in a second European language.
