Full Stack Engineer

About the job

Description

Our client is an embedded finance platform. They partner with e-commerce platforms, marketplaces, and payment providers to offer fast, flexible business financing to SMEs, powering funding decisions and disbursements directly inside our partners' products.

About This Role

We're hiring a senior full-stack engineer who owns real problems end-to-end and shapes how the team builds, from API design and frontend experience through to backend services, production reliability, and launch. You already use AI as part of how you think, build, test, and ship.

You'll write code that moves money in production, design and modernize the platform across the stack, and lead delivery of partner-facing and merchant-facing features as the platform is rebuilt. You'll work in a small engineering team with direct access to product, design, and compliance, own architecture in your domain, lead design reviews, mentor mid-level engineers, and partner with architects and team leads on cross-domain decisions.

What You'll Do

• Design and own features across the stack that move money and manage lending balances across a range of domains, including onboarding, KYC and KYB, underwriting, funding disbursement, repayments, and other supporting services.
• Lead delivery of partner-facing and merchant-facing features that customers use every day, from the interface through to the services behind them.
• Own production health for your domain, including reliability, observability, on-call, and incident response.
• Lead cross-functional delivery with product, design, and compliance from problem framing through launch.
• Lead design reviews, set technical direction for your domain, and mentor mid-level engineers.
• Use agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) daily across the SDLC, and lead modernization from legacy services into the modern stack alongside architects and team leads in your domain.

Must-have

• 6 to 10+ years building production web applications, end-to-end.
• Strong frontend proficiency with Vue.js, React, or equivalent.
• Strong backend proficiency in C# / .NET preferred; other OOP languages welcome (Java, Kotlin, Go, or equivalent).
• Solid SQL and relational database fundamentals.
• Writing and maintaining tests as part of how you ship.
• Daily use of agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) across the SDLC.
• Production experience on AWS, including hands-on deployment, CI/CD pipelines and modern deployment practices, and native services such as SQS, DynamoDB, S3, ECS, and Lambda.
• Strong system design and architecture experience, including service-oriented or microservices and event-driven patterns.
• Payments, FX, or regulated-industry experience.
• Track record of technical leadership: mentoring engineers, leading design reviews, and making architecture decisions in your domain.
• Strong communication and collaboration across engineering, product, and design.
