What we are looking for

3+ years experience as professional software engineer with focus on TypeScript/NodeJS/React.

A collaborative, empathetic engineer who enjoys achieving results together with others.

Hands-on experience designing and implementing high-quality web-based solutions.

Ability to break down complex business problems and deliver solutions that are simple, robust, and effective.

Solid experience building and operating SaaS solutions on a public cloud platform (Azure, AWS, or GCP).

Experience and eagerness to work on both frontend and backend (we use React and NestJS).

Solid understanding of modern frontend fundamentals (state management, component architecture, performance) and backend fundamentals (API design, service patterns).

Your mission

Build and evolve a fast-growing B2B SaaS product together with an interdisciplinary product, design, and engineering team.

Collaborate closely with Product and Design to create scalable, high-quality user experiences that customers genuinely value.

Contribute to and shape our cloud-native platform (Azure, React + Vite frontend, Node.js (NestJS) and Python backend services, LLM-powered capabilities).

Drive improvements in developer productivity, code quality, testing, and automation together with the engineering team.

Take ownership beyond your code by actively contributing to technical decisions, architecture, and best practices.

Help shape our engineering culture and working environment into one that is collaborative, pragmatic, and enjoyable.

Stay current with industry trends and proactively identify opportunities for technical and process improvements.

About you

You care deeply about building software that is useful, well crafted, and easy to work with. You enjoy thinking about the bigger picture, not just how something is built, but why it is built and how it will be used.

You are comfortable taking ownership, making thoughtful trade offs, and discussing technical decisions openly with your team. You value pragmatic solutions over perfection and know when to keep things simple.

You enjoy working in a product driven environment where engineers collaborate closely with product managers and designers. You like learning new things, improving how you work, and contributing to a positive team culture.

We have a strong, international team of people with experience both in large enterprises like Google and Microsoft, but also experience in founding and growing tech startups. We push each other to higher degrees of product and engineering excellence, while looking at everything we do with a business mindset.

You’ll have the autonomy to drive design decisions and make a real impact, with little bureaucracy and meetings, all within a supportive and innovative environment. We foster a culture of creativity and collaboration, with regular team activities, both virtual and in person.

Archlet is on a healthy growth trajectory, already has renowned customers like Walmart and PepsiCo, and has an exciting product roadmap that needs you to succeed.
