Software Engineer Typescript H/F Skaleet

Skaleet is a dynamic and fast-growing tech company specializing in Core Banking Solutions. We help financial institutions in 15 countries to innovate, scale, and deliver superior banking experiences to millions of end-customers.

At Skaleet, we thrive on collaboration, creativity, and a shared passion for redefining the future of banking.

Join us in our journey to transform the financial industry!

We are constantly looking for talented individuals to help us continue developing our solution and achieve our goals: free European banks and fintechs from legacy core banking systems, so they can finally deliver modern, modular, real-time banking experiences, without compromising on compliance or robustness.

Our ambition is to build the pan-European leader in modern Core Banking.

Over the next five years, our ambition is to become the platform of choice for European financial institutions to:

• modernize their infrastructure

• scale their operations

• rapidly launch new banking services

💡 Context

As we continue to scale and support increasingly demanding Tier-1 financial institutions, we are strengthening our Software Factory to drive the evolution of our core banking platform.

You will join the Savings & Credit squad, a cross-functional team responsible for building and maintaining the savings, overdraft and credit features at the heart of our platform. These are high-stakes, high-complexity domains where financial accuracy, regulatory compliance, and real-time processing are non-negotiable.

As a TypeScript Software Engineer, you will directly contribute to the development and resilience of a modular banking platform running in production within mission-critical environments.

Your role will go beyond feature implementation: you will actively participate in building a reliable, scalable, and sustainable technological foundation supporting real financial flows with high business impact.

You will operate in an environment where code quality, performance, and system stability are not optional — they are fundamental requirements.

🤖 AI-driven development

At Skaleet, we develop our features with AI. Most of our developers are AI-driven, from design to development.

We expect you to be more than comfortable with AI: it will be part of your daily work as a developer.

👉 Your future missions

You will play a key role in ensuring the quality, reliability, and long-term evolution of our platform, contributing to developments with strong business impact.

1. Contribute to a robust and scalable technology foundation

• Develop and deliver critical features (savings products, overdraft mechanisms, credit, interest calculation engines) while adhering to high standards of quality, maintainability, and performance.

• Work primarily on backend development in TypeScript (≈80%), while also contributing to frontend evolutions (≈20%), maintaining an end-to-end understanding of product behavior.

• Ensure clarity, testability, and long-term sustainability of the codebase, helping control technical debt and support continuous platform evolution.

• Actively contribute to technical discussions and propose architectural or design improvements when relevant.

2. Elevate engineering excellence (Software Craftsmanship)

• Apply and promote best development practices: clean code, rigorous code reviews, meaningful documentation, and automated testing.

• Contribute to strengthening our testing pyramid (unit, integration, end-to-end) to improve release reliability and reduce production risk.

• Actively participate in continuous improvement initiatives, reinforcing a culture of technical excellence within the squad.

• Operate in an Agile framework with strong attention to specification quality and deep understanding of business constraints.

3. Operate in mission-critical and high-impact environments

• Build and maintain features used in production by financial institutions, where performance, resilience, and availability are essential — especially in the savings, overdraft and credit domains, where precision and consistency are business-critical.

• Collaborate closely with Product, QA, and Delivery teams to translate complex functional requirements (e.g. interest rate rules, overdraft eligibility, regulatory constraints) into robust technical solutions.

• Participate in incident analysis, root cause investigations, and resilience improvement initiatives to continuously strengthen platform reliability.

• Take part in on-call rotations, contributing to service continuity and operational excellence.

4. Contribute to team dynamics and engineering maturity

• Share knowledge and continuously learn from peers in a culture of collective progression.

• Actively engage in technical discussions and contribute to strategic engineering decisions within the squad.

• Support the ongoing maturation of our Software Factory by bringing structure, rigor, and pragmatic engineering thinking to complex challenges.
