We provide an embeddable widget and API for crypto-native wallets to allow their users to buy cryptocurrencies globally, with over 130 payment methods. 

Our tech is used by Coinbase, Exodus, Opera browser and hundreds of other platforms for their 'fiat onramping' stack. By partnering with the best fiat-to-crypto payment gateways and presenting them in a single plugin their users can then buy crypto easily in-platform when needed. This is one of the most important intersections for web3/meta.

We are looking for a Senior Fullstack Engineer with a keen interest in the development of modern web platforms, as well as the ambition for personal growth and innovation. As part of a cross-functional team, you’ll be taking a lead on some of the most important and core parts of our platform.

About You and Job Responsibilities:

You’re pragmatic, learn quickly, and have a proven track record of experience. You communicate well and enjoy working in a startup team. Above all, you’re curious about the world and passionate about what you do. The thought of working on one of the hottest platforms that bridges the traditional financial world with the world of cryptocurrencies genuinely excites you.

As a fullstack engineer, you're passionate about building high-quality scalable applications end-to-end. Most likely you have stronger engineering background in either frontend or backend. Yet you can still be productive in both while possessing expertise in one or more common server-side programming languages (such as Java, Golang, Python, C#, JavaScript/Node, etc).

On the frontend side, you are capable of developing web applications in TypeScript (or JavaScript) and dealing with HTML/CSS. You have worked with at least one of the popular frontend frameworks (such as React, Angular, or Vue.js), and build tools (like grunt, gulp, bower, npm, or webpack).

And when it comes to the backend, you have prior experience in building data-intensive applications and working knowledge of database modeling and design. You feel comfortable when dealing with message queues, streams, caching layers, and REST APIs, as well as likely have some experience integrating with external APIs too.

On top of all that, you're familiar with version control workflows, as well as have a good understanding of security and best practices for developing secure applications (e.g., the “Twelve-Factor App” principles sound to you at least familiar and fairly logical). Automated testing and testability are not an afterthought for you either.

Our tech stack:

• Client-side: TypeScript / React / SCSS

• Server-side: TypeScript / NodeJS / AWS Lambda (Serverless) / DynamoDB / Snowflake

We offer:

Onramper is a pre-SeriesA startup going through a stage of tremendous growth. As such, you have an opportunity to help build a unicorn with a close-knit talented team, while enjoying wide autonomy, ownership, and responsibilities over the products and solutions you will be working on.

Benefits & Perks:

• Competitive compensation
• Become a part-owner! We offer equity as part of your compensation package
• Top-notch MacBook Pro and other necessary gear
• Awesome office in the heart of Amsterdam. We don’t have a mandatory work-from-office policy, being remote-first. Yet you are always welcome to enjoy its facilities
• Team events 
• Thursday drinks (optional) and intra-team table tennis championship
• An international team with diverse nationalities/backgrounds

Location:

While we have a preference for those that can join our office in Amsterdam, we're open to applicants from countries in timezones ranging from CEST to UTC+4. Longer term, there's possibilities of Visa Sponsorship.

What We’re Looking For:

5+ years of software development experience building and shipping production applications, with a focus on backend systems or API-driven services. Strong proficiency in TypeScript/Node.js and/or Rust. (Our core services are built with these languages.) You can quickly pick up new languages and technologies as needed. Demonstrated experience designing, building, and scaling web APIs or microservices – you have tackled challenges in system design, performance tuning, and reliability for high-traffic services. Hands-on experience with relational databases, especially PostgreSQL – from data modeling and querying to performance optimization. Familiarity with modern cloud and container infrastructure. You’ve worked with containers/orchestration (Docker, Kubernetes) and deployed services on cloud platforms (we use GCP). Passion for code quality and automation. You write clean, maintainable code and have experience with automated testing and CI/CD pipelines (GitHub Actions or similar) to ensure smooth deployments. Excellent communication and collaboration skills. Comfortable working in a remote, distributed team and coordinating across time zones. Self-driven and ownership-minded. You take initiative, have a bias for action, and can manage projects end-to-end in a fast-paced environment.

We’d Also Like to See:

Blockchain/Web3 experience or interest. Familiarity with decentralized networks, or a keen interest in learning blockchain tech. Experience building developer-focused products. For example, working on developer tools, SDKs, or API platforms – understanding what makes a great developer experience. Exposure to performance tuning and observability.
