Senior Full-Stack Engineer (Remote)

Build the systems that turn a first website visit into an active app subscription. At Applause, you will work directly with the business, shape technical solutions, and build reusable systems across our consumer app portfolio.

About Applause

Applause acquires exceptional consumer apps and invests in their continued development and growth. Our portfolio includes Strongbox, Voice Dream, Nomorobo, and Meditation Moments.

Alongside our apps, we build the web systems that help people discover our products, sign up, make purchases, and access what they have paid for. We want that journey to feel simple and reliable, supported by technology we can reuse across multiple apps.

This is a remote role within an international team. Our working language is English, and we have offices in Amsterdam and New York.

The role

As a Senior Full-Stack Engineer, you will own web systems across the full customer journey: landing pages, onboarding, checkout, account linking, entitlements, app activation, lifecycle events, and measurement.

You will report to Alex, our VP of Engineering, and collaborate with business, product, app engineering, and data colleagues.

Not every request will arrive as a detailed specification. You will ask questions, clarify requirements, identify dependencies, and turn business needs into sound technical systems.

Your work will include:

Designing, building, and maintaining frontend and backend systems.
Developing customer journeys from initial website visits through app activation.
Connecting accounts, payments, subscription status, and access rights.
Creating reusable modules that support multiple apps.
Implementing events and integrations that make the customer journey measurable.
Maintaining production reliability and resolving issues.
Explaining technical choices and trade-offs to technical and non-technical colleagues.

Our current stack is Next.js and React on the frontend, with Python on the backend. Exact language experience is flexible: we care more about your systems thinking, engineering judgment, and ability to deliver independently.

What you bring

You are a senior engineer who is comfortable building across the frontend and backend. You have personally owned a production system and can explain how it works, why you designed it that way, and what you would improve.

We are looking for:

Strong full-stack engineering experience.
The ability to gather requirements and turn an incomplete business request into a technical solution.
Experience with databases, APIs, and integrations.
An understanding of reliability, maintainability, and the customer experience.
The ability to deliver with limited guidance and remain accountable after release.
Confidence working directly with business, product, and data colleagues.
Clear written and spoken English.

Experience with subscriptions, payments, account management, or web-to-app journeys is a plus.

You do not need previous people-management experience. This role can suit a strong senior engineer who wants to grow into leadership or someone already ready to take technical ownership of a web team. In either case, you will remain hands-on.

What you can expect

A remote role with ownership of systems used across multiple consumer apps.
The opportunity to shape requirements, architecture, and technical direction.
Direct collaboration with the business and our VP of Engineering.
Room to grow towards technical leadership.
An international team that values autonomy, clear communication, and measurable outcomes.
