If you refuse to compromise on elegance, functionality, and inclusivity, and you're ready to make a positive impact on the web for millions of users, then you might be just the person we're looking for.

You won't just write code—you will build the future of digital accessibility. Here, your code won't end up in a virtual drawer. It will be used by countless people, and together with AccessiWay, you will help make their lives simpler, more seamless, and accessible.

What You'll Do (prepare For a Bit Of Everything) We are looking for a brilliant, curious, and proactive Mid-level / Senior Fullstack Developer. You will participate in the design and development of services focused on delivering an exceptional user experience, taking full ownership of your role and actively contributing to building high-quality products.

Frontend: React and TypeScript are your bread and butter. You work with Hooks, TanStack Query, Tailwind CSS, and Zod, translating mockups into polished, high-performing, and accessible interfaces. You write tests using Vitest and Playwright.

Backend: You build and maintain Lambda functions, ECS services,



and REST APIs behind API Gateway. You work with SNS and SQS for asynchronous workflows, and you navigate between Aurora PostgreSQL and DynamoDB, knowing exactly when to use which.

Performance & Quality: You apply best practices, actively participate in code reviews, and keep an eye on error monitoring with Sentry. 3+ years of fullstack experience, with a solid grasp of both frontend and backend. ~ Fluent TypeScript, both client-side and server-side — clean types, maintainable code, zero random anys scattered around. ~ Familiarity with AWS: hands‑on experience with at least a few of the following: Lambda, SQS/SNS, ECS, API Gateway, RDS/DynamoDB. ~ Solid database foundation: PostgreSQL, schema design, and query optimization are second nature to you. ~ Eye for detail: polished UI, optimized queries, and tests covering the edge cases that actually matter. ~ Python in your arsenal. Curiosity about cloud infrastructure and a desire to grow in that direction — we use AWS CDK in TypeScript, and you'll be able to contribute to Infrastructure as Code as you settle in. Knowledge of Firebase (Authentication, Remote Config).

Experience with accessibility testing tools (like Lighthouse or Axe). the answer is yes—if you love solving problems, creating beautiful and useful things, and above all, if you want to be part of a project that truly matters. Accessiway is a European leading company in digital accessibility, focused on making the digital world accessible to everyone. #
