Meaningful Clients Across Industries

Siili One has been operating since 2019, building a solid foundation through its parent company's hundreds of direct client relationships and impactful projects across various industries. Here, you get to work directly with clients — to influence, not just execute.

Led by Seniors – Who Also Build

Our focus is on Lead-level expertise: seasoned professionals who take charge of client work by staying hands-on. At Siili One, leading means taking responsibility through action. You can focus fully on your expertise – and when you need a sense of community or a helping hand, we’re right here with you.

Top Benefits and a Skilled Community Around You

Our salaries and benefits are among the best in the industry, and our offices are modern and comfortable. Your work environment is enriched by the entire Siili Group and our ecosystem: the AI-driven strategy of our parent company, the deep specialization of our subsidiaries, and a partner network ranging from freelancers to key players in the field. We don’t exclude others – we build better together.

Endgame – Why Go Anywhere Else?

Siili One is home to over 100 experienced professionals with an average of more than 15 years of experience. People stay with us: Siili One professionals have been part of the Siili family for an average of 8.8 years (as of 4/2025) – more than double the industry average of 4 years.

Why? Because we get the essentials right:
– Compensation
– Benefits
– Freedom and purpose in your work
– Clients that truly challenge and inspire

When you join Siili One, you’re not on your way to the next consultancy — you’re arriving at a place worth staying.

And when people do eventually move on, it’s typically into product development, a new industry, or entrepreneurship. Rarely to another consultancy — and there's no need to. Here, you’re part of a crew that knows their craft and thrives in every situation.

This is the endgame of software consulting. And in the best possible way.

What About the Parent Company?

Yes – Siili Solutions is a great choice too.

The image shows a ranking of Finland's most attractive employers in 2024, based on a nationwide survey.

The list is from a study conducted by Academic Work, targeting young professionals in Finland. According to the results, Siili Solutions ranks among the Top 10 most attractive employers, alongside companies like Google, Supercell, KONE, Microsoft, and Apple.

This highlights the strong employer brand of Siili Solutions – our parent company – and reinforces why joining the Siili family is a solid choice.

A Diverse Client Base

Siili has over 400 active client relationships, with Siili One having served more than 200 of them – some of which are direct Siili One clients. Our client base is broad and varied: listed companies, SMEs, startups, scaleups, and public sector organizations.

Different Industries and Development Environments

We don’t draw industry lines. We choose clients who share our values based on responsibility and a collaborative mindset – and we understand that clients choose us, too. That’s why we build long-term partnerships based on trust. Through your work, you'll get to engage with a wide range of environments, technologies, and teams – from small, agile setups to cross-functional development in large organizations.

Contribute to New Client Opportunities

As a Siili One consultant, you also have the chance to bring your own expertise and ambition into opening new client relationships together with our business development team. At Siili One, business development is, however, a shared responsibility – each of us contributes in our own way. So, what kind of problems do you enjoy solving? And what kind of clients would you love to work with?

Client Needs First

At Siili One, consulting starts with understanding the client's real need and finding the right solution – not just writing code or filling a role. Client-centricity is at the core of everything we do: we listen, engage in dialogue, and respond according to the situation.

Beyond Tech – It’s About Interaction

Communication is a key skill: alongside expertise, we value the ability to communicate clearly, build trust, and foster collaboration. Technical skills are a given – but their value only becomes real when used to benefit the client.

Colleagues to Think With

At Siili One, you’ll work among seasoned professionals who don’t keep their expertise to themselves – they share it. You’ll have the space to shine, support when you need it, and the opportunity to shape how your work is built.

We Value Different Ways of Working

Both are equally respected and welcomed at Siili One – what matters most is finding a model that fits your life situation and personal goals.

Employment Offers Community and Continuity

As an employee, you’ll have a supportive work community around you – even between client projects. You’ll benefit from sales support, active peer sparring, and learning opportunities such as AI training and coaching for cloud certifications.

Freelancing Brings Flexibility and Options

As a freelancer, you can be part of the Siili One network, working with the same clients and in the same projects as our in-house experts. We always hire when possible, but when a permanent position isn’t available, freelancing is an excellent alternative for collaboration.

Your Situation and Our Possibilities Both Matter

What matters most is that we find a way of working that fits you. The form of collaboration can change as life does – from freelancing to employment or the other way around. We aim to offer flexibility whenever it's possible for us too.
