Senior Software Engineer

AKQA • Washington, DC

3h • $3,000 - $3,200 • Remote

About The Position

At AKQA (part of WPP), we believe in the imaginative application of art and science to create beautiful ideas, products and services. With an entrepreneurial and collaborative approach, we design adaptive digital services and applications that capture the imagination, delivering impressive returns for our clients.
Senior Software Engineers at AKQA are inspired by technology and driven by a passion for creating innovative, well-crafted solutions. They thrive in highly skilled, opinionated teams where ideas are exchanged openly and executed with discipline and care. They bring strong product instincts to their work, taking genuine ownership of outcomes rather than just executing tasks, and they consistently look for ways to improve both what they build and how they build it.
We are seeking a Freelance Senior Software Engineer to support a forward-thinking investment group building a sophisticated, fintech-adjacent digital platform. This is not a generic backend engagement. You will be working across a modern full-stack TypeScript and Next.js product, contributing to investor-facing interfaces, transactional workflows, admin tooling, and the data integrations that tie it all together. Correctness, security awareness, and architectural clarity matter deeply here, and the ideal candidate brings both the technical depth and the product-minded judgment to deliver with confidence in that kind of environment. This is a remote freelance role from July 1 through December 18, 2026.

Requirements

• Strong, production-proven TypeScript and Next.js App Router experience is essential
• Full-stack capability across both server-side logic and client-side React, with a genuine appreciation for UI craft and accessibility
• Architecture discipline: you think carefully about boundaries, dependencies, and data flow, and you build systems that are easy to reason about and extend
• Security and authorization awareness, particularly in contexts where data sensitivity, auditability, and access control are non-negotiable
• A product-minded engineer who takes ownership of outcomes and brings judgment to prioritization, tradeoffs, and quality
• Comfortable articulating technical decisions clearly to both technical and non-technical collaborators
• Thrives when faced with new challenges and consistently looks to improve client deliverables and team practices

Nice To Haves

• Comparable depth with relational databases and ORMs
• Comparable tooling to Vitest
• Experience with Contentful
• Experience with Databricks or Azure

Responsibilities

• Deliver full-stack feature work across a modern TypeScript and Next.js App Router codebase, including server actions, API routes, and service-layer logic
• Build accessible, responsive, design-system-driven UI in React, bringing the same care and discipline to the front end as to the back end
• Design and maintain clean service, domain, and persistence boundaries that support a scalable, maintainable, and auditable codebase
• Work with PostgreSQL via Prisma and Supabase, or bring comparable depth with relational databases and ORMs
• Implement and maintain authorization-aware data access patterns, with a strong understanding of auth, session management, and security considerations in a regulated or fintech-adjacent context
• Build and maintain form-heavy transactional workflows using schema validation approaches such as React Hook Form and Zod
• Integrate with CMS platforms, ideally Contentful, to support content-driven product surfaces
• Write meaningful tests across unit, component, and integration layers using Vitest or equivalent tooling, with a focus on testing the flows that matter most
• Work within a CI/CD pipeline using GitHub Actions and deploy to Vercel, maintaining delivery hygiene and production reliability
• Bring comfort and prior experience working with regulated workflows, investor portals, admin tooling, or data integrations involving platforms such as Databricks or Azure
• Collaborate with product, design, and engineering partners to shape solutions, not just implement them

Benefits

• AKQA is an equal opportunity employer and considers applicants for all positions without discrimination or regard to particular characteristics. We are committed to fostering a culture of respect in which everyone feels they belong and has the same opportunities to progress in their careers.
