Platform Engineer

Job Overview

We’re hiring a Platform Engineer to help world-class financial institutions automate away their backoffice. This is a hands-on role for an engineer who loves building reliable, elegant backend systems that make complex business processes feel simple. You’ll work on the heart of our platform — APIs, data models, and integration layers — ensuring everything we ship is fast, secure, consistent, and easy to extend. You’ll collaborate closely with our founder and product engineers to design scalable backend architecture, bring new services online, and integrate third-party systems securely and efficiently. You’ll have ownership over technical direction and see your work have a direct impact on the company’s success.

Key Responsibilities

• Backend Integrations & Platform: Own and operate the backend systems that integrate with 3rd-party providers (e.g. authentication, payments, document management)


• Design robust integration frameworks that simplify and standardize how we connect to external systems


• Evolve shared libraries, templates, and workflows to enforce standards and reduce friction


• Partner with other engineering teams to improve system performance, scalability, and reliability


• Use AI-powered tools to accelerate development and discover innovative solutions to complex technical challenges


• Apply strong computer science fundamentals to design and operate systems that handle large-scale data efficiently


• Delivering reliable solutions on time and with attention to detail


• Scalable and Secure Infrastructure: Design, build, and maintain cloud infrastructure that is secure, observable, and cost-efficient


• Implement scalable CI/CD pipelines that accelerate safe deployments


• Drive adoption of SaaS, IaC and best practices for environment management


• Ensure systems are resilient through monitoring, alerting, and automated recovery
