As a Full Stack Typescript Developer, you will work across the full cloud-edge system, from our SaaS platform to our embedded robot interface, including the secure connectivity that ties them together!

Who we are

We are a fast-growing, high-tech and innovative company with one mission: Powering clean transportation by handsfree charging! We create reliable effortless charging solutions by combining soft robotics, cutting-edge computer vision, and value-added services. Rocsys enables its customers to electrify their fleet sustainably.

Our headquarters are in The Netherlands, and we have an office in Portland, OR, USA.

Join us, and together, we can power clean transportation!

You make the difference

Rocsys relies on your contribution to accelerating the adoption of electric mobility by building the software behind our autonomous charging technology. Our work enables reliable, scalable charging solutions that support cleaner transportation and a more sustainable energy ecosystem.

You will be part of our small, dedicated cloud team, giving you real ownership and visibility over work vital to the success of our company. Together with your teammates, you shape the cloud platform and connectivity layer, while collaborating closely with a group of around ten developers across various domains and our operational teams.

This is not just dashboard development: Your code runs both in the cloud and inside real-world robotic systems operating in the field supporting clean technology that makes a tangible difference.

In this role you will

Develop and extend Rocsys’ internal and customer-facing SaaS portals.

Build and maintain web interfaces embedded in our charging robots.
Design and implement tools that integrate robot software with cloud services.
Develop high-quality front-end and back-end solutions in TypeScript across the full stack.
Translate functional requirements into clean, maintainable, and scalable implementations
Take ownership of features from concept to production — whether deployed in the cloud or on the robot.
Be able to travel to the office as needed.

Your contribution

You ensure performance, reliability, and security across both connected and embedded environments, contributing to robust systems that operate seamlessly in real-world conditions. You also actively contribute to architectural discussions within the team, helping to evolve our technical landscape as we scale and improve our platform.

6+ years of professional web development experience
Strong expertise in TypeScript, JavaScript, HTML, CSS
Experience with React (or similar modern frameworks)
Backend experience with Node.js / TypeScript
Experience with PostgreSQL or other relational databases
Experience designing and consuming RESTful and/or GraphQL APIs
Experience building secure, production-grade applications
Familiarity with Linux, Git, and Docker
Pragmatic mindset: balancing quality, speed, and maintainability

Nice to have:

Experience with embedded or constrained environments
Working on systems combining hardware and cloud
Performance and reliability optimization
AI-assisted development tools
NestJS, AWS (or similar), Infrastructure as Code (Terraform)
OAuth and modern authentication flows
Scalable SaaS platforms

Your personal skills:

Comfortable switching between cloud systems and embedded contexts.
Independent and proactive, while working closely with a multidisciplinary team.
A team player, experienced in agile/scrum teams.
Structured and clear in your communication (English, required).
Curious about how software and hardware interact in real-world systems
You enjoy prototyping and exploring solutions in areas that are still evolving
A strong eye for UX and building efficient, intuitive interfaces.

What we offer

We believe great work happens when people have trust, autonomy, and balance.

Hybrid working model with flexible hours
32–40 hour workweek
Salary range: €6,000–€7,500 per month (depending on experience)
Employee stock option plan
25 vacation days, with the option to purchase 5 additional days
Bicycle plan to support sustainable commuting
Free daily vegetarian lunch
Wednesday afternoon drinks
Strong career growth opportunities as the company scales
Office in Rijswijk, easily accessible by public transport

This role is based in the Netherlands. Applicants must currently reside in Europe and be legally authorized to work within the European Union.

Our company values

We own it!
Relentlessly Inventive
People with Passion
Leave a Better Planet

We are keen to get to know you! Apply with your CV and a few words on why you would like to join Rocsys. We look forward to your application!
