Taktile empowers financial institutions to transform into truly AI-native organizations. We’re growing rapidly with enterprise customers across banks and insurance companies, and we’re looking for a Senior Full-Stack Engineer.
Taktile helps financial institutions make smarter, safer decisions with the power of AI. Our software gives teams the tools to automate complex decisions, from customer onboarding and underwriting to fraud detection, with full visibility and control. By combining AI with a rich ecosystem of financial data, we enable companies to adapt their decision-making in real time as markets, customer behavior, and risks evolve.
We're looking for a Senior Full-Stack Engineer to be a founding member of the Web SDK team and help shape this product from the ground up. You'll own the architecture of a unified client-side SDK that abstracts identity verification, device intelligence, and document capture behind a single, elegant integration, used by financial institutions to onboard customers securely and seamlessly. This is a high-impact, high-ownership role with a clear path to leading the team as it grows.
If you've built SDKs, shipped embeddable components, or worked on developer-facing products that run in other people's browsers, and you're excited about doing it again at the intersection of fintech and platform engineering, we'd love to talk.
Architect the SDK from scratch: Design and build a client-side JavaScript/TypeScript SDK that orchestrates multiple third-party vendor scripts behind a unified, headless API.
Build the hosted verification experience: Create a secure, embeddable web application that renders interactive identity verification flows with a polished, brandable UX.
Own reliability end-to-end: Establish versioning strategies, staged rollouts, and CI/CD pipelines for client-side code that runs in customer browsers.
Solve hard integration problems: Wrangle vendor SDKs that each have their own quirks, lifecycle hooks, and failure modes, and make them work together seamlessly.
Shape the product and the team: Collaborate with Product, Design, and customers to define the SDK's developer experience. As the team grows, you'll have the opportunity to step into a tech lead role.
Work directly with customers: Engage with early adopters to understand their integration environments and ensure the SDK works flawlessly in the real world.
Hybrid role based in Berlin or London. We collaborate in person regularly and don't offer remote-only for this position.
Fluent English required. You'll write design docs, review PRs with context, and occasionally join customer calls.
Strong engineering fundamentals across the full stack: you're equally comfortable designing clean APIs and building responsive, accessible front-end experiences.
Deep understanding of how browsers work: the DOM, security models (CSP, CORS, iframe sandboxing), caching, script loading, and performance.
Comfortable operating systems in production and participating in incident response as part of a team rotation.
5+ years of professional software engineering experience
At least 2 years building and shipping a client-side SDK, embeddable widget, or developer-facing JavaScript library used by external consumers. You know what it takes to version, distribute, and support code that runs in environments you don't control.
Production experience with TypeScript/JavaScript on both client and server. You've built modern front-end applications and understand bundling, tree-shaking, and cross-browser compatibility deeply.
Experience with iframe-based architectures, postMessage communication, and sandboxed execution environments.
Proficient in backend development (Python is a plus), you can build the APIs and configuration services that power the SDK.
Prior industry experience with public cloud providers (preferably AWS).
Experience in identity verification, fraud prevention, or fintech - you've worked with providers like Socure, Vouched, Onfido, Fingerprint, or ThreatMetrix.
Familiarity with media APIs (camera access, image capture, WebRTC) and the nuances of building permission-driven UX flows.
Experience building developer tools, documentation, or SDKs with a focus on great developer experience.
Previous experience as a tech lead or strong desire to grow into one, you enjoy mentoring, setting technical direction, and making architecture decisions that scale.
Knowledge of security and compliance considerations (SOC2, PII handling) for client-side applications in regulated industries.
Work with colleagues that lift you up, challenge you, celebrate you and help you grow. We come from many different backgrounds, but what we have in common is the desire to operate at the very top of our fields. If you are similarly capable, caring, and driven, you'll find yourself at home here.
Experience a truly flat hierarchy and communicate directly with founding team members. Having an opinion and voicing your ideas is not only welcome but encouraged, especially when they challenge the status quo.
Learn from experienced mentors and achieve tremendous personal and professional growth. Get to know and leverage our network of leading tech investors and advisors around the globe.
Receive a top-of-market equity and cash compensation package.
Get access to a self-development budget you can use to e.g. attend conferences, buy books or take classes.
Receive a new Apple MacBook Pro, as well as meaningful home office set-up.
We're eager to meet talented and driven candidates regardless of whether they tick all the boxes. We're looking for someone who will add to our culture, not just fit within it. We strongly encourage individuals from groups traditionally underestimated and underrepresented in tech to apply.
We seek to actively recognize and combat racism, sexism, ableism and ageism. We embrace and support all gender identities and expressions, and celebrate love in its many forms. We won't inquire about how you identify or if you've experienced discrimination, but if you want to tell your story, we are all ears.
