Senior Software Engineer Job at AKQA (Washington DC)

Job Description

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

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
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
