About Kwan

At KWAN, your career is bigger than one project. You join a real team, on a long-term project, at a company where technology is the business. And when you are ready for something new — a new stack, a new industry, a bigger role — we find that next step with you, without you having to start over somewhere else.

From day one you have a dedicated People Experience Partner: one person accountable for your growth, not your allocation. They know where you want to go, and they help you get there.

You keep learning as technology moves (AI included). Your impact is seen and recognised. Pay and expectations are talked about openly. And you work remote-first, with hubs in Lisbon and Porto for when you want people around.

Grow with clarity. Be treated with respect. Build things that matter.

Apply — if your profile is a match for this role, you will hear from our Talent team within 48 hours. If it is not the right match this time, we will reach out as soon as we find a role that fits you better.

We connect IT professionals with projects that match their skills, professional experience, and goals, then we offer a career progression program, delivered by in-house specialists - our People Experience Partners - to guide them through our journey with us.

What we offer:

A project that matches your skills and ambitions, as well as your preferences for working policies and culture.
A competitive salary with awesome benefits and opportunities to leverage your knowledge and network to earn additional income.
An empowering and respectful work culture enriched with social and learning events.
A People Experience Partner specially assigned to you - your go-to career guide, responsible for supporting your growth, facilitating training, and ensuring your work-life balance at KWAN.

At KWAN, they make sure that I feel comfortable with the client I’m working for and that what I’m doing aligns with my career aspirations.
