Job description

Meet Sievo

Sievo is the global category leader in procurement analytics. We process 2% of global GDP annually and serve the largest companies in the world to generate cost savings, understand their procurement data, make data-driven decisions, reduce emissions, drive supply chain resilience, and beyond.

At the core of our success are talented people from all over the world with different backgrounds and perspectives. Our 400+ Sievonians are based across Helsinki, Chicago, Bucharest, London and Paris. Our core values are caring, exceeding, and honesty - values that make us grow bigger and better, not bigger and bitter.

We’re taking on new challenges at an accelerating pace. In 2026 we have already opened new offices in the UK and France, completed our first acquisition, made substantial breakthroughs in our data businesses, massively adopted AI in internal operations, and embedded new AI capabilities in the product we offer to our customers.

About the role

To sustain and accelerate our growth, we’re hiring our first ever Chief of Staff. This role is a front-row seat to decision making and running operations at a growth scale-up with active contribution to management team meetings. If you are looking for an easy role, this likely isn’t it. If you want a steep learning curve with real exposure, this might be the best next step in your career.

The role is to be based on our Helsinki HQ reporting directly to Sievo’s CEO and co-founder, Sammeli Sammalkorpi. The expected growth trajectory of the ideal Chief of Staff is to be in this role for 18-24 months before continuing their career at Sievo to other responsibilities.

Core responsibilities

• Owning the company’s operating rhythm. This includes planning annual, quarterly, and monthly activity cadences with the management team and wider leadership and following up on its execution.


• Involvement in strategic, cross-functional high impact projects, such as mergers and acquisitions, strategic growth projects, regional launches, and similar initiatives.


• Managing executive meetings by agenda setting, needed preparations, and follow-up, driving clarity and accountability for the management team.


• Preparing key communication material for the CEO, including All Hands and other internal communications, customer and prospect events, and board meetings, being accountable for effective communications.


• Providing “biggest bang” leverage wherever it’s needed as a force multiplier to CEO. This is not an Executive Assistant role, but responsibilities are flexible enough to take on operational tasks when that’s the highest-leverage thing to do that day. For instance, you will be preparing board decks, but occasionally you will also be ensuring that presentation room has an HDMI cable.

Requirements

• A few years of experience in management or strategy consulting, or similar analytical role.


• Strong analytical capability to be able to create structure from ambiguous, conflicting data and inputs.


• Great organizing skills to bring structure to a chaotic, fast-growing environment.


• Excellent English written and verbal communication to turn loose, high-level direction into crisp, communication-ready material in PowerPoint and other materials. Finnish is not required.


• Exceptional interpersonal skills to interact with senior stakeholders within and outside the company in strategic projects. With the limited direct mandate, you establish yourself as trusted collaborator whilst driving things forward with humility, not as a corporate asshole.


• AI-first mindset and curiosity towards the changing world. You are up to date with AI capabilities and interested in building systems for efficient AI adoption. Not only embracing those yourself but actively advocating for these for the whole company.


• High work ethic and flexibility. This isn’t a 9-to-5 role as in a growth scale-up things cannot be fully planned. Sometimes something important might come up with short notice, but it still needs to be taken care of.

We offer

• Hands-on exposure to running and scaling a business. You’ll see first‑hand and participate in shaping how strategy is set, debated and carried out in a growth company.


• Learning directly from the CEO and management team as your closest colleagues internally.


• Real ownership and visible impact with Sievo’s operating rhythm as yours to design and develop further.


• A launchpad for your next high impact role at Sievo shaped around the strengths and interests you have discovered along the way in this role.


• An opportunity to drive AI adoption in how the management team works.


• A culture built on caring, exceeding and honesty.


• Employee benefits including equity program, extensive healthcare, Edenred benefits, Auntie services, home care for a sick child, home internet connection and mobile phone subscription, and snacks at the office.

This is a full‑time, permanent contract with a planned gross salary of 6000-8000e/month depending on skills and experience. The onsite work expectation for this role is minimum two days per week at Sievo’s Helsinki HQ. There might be occasional international travel required.

At Sievo, we celebrate and support differences and strive to create a culture where everyone feels valued and included. As an Equal Opportunity Employer, we do not discriminate against any individual in hiring or employment based on gender, gender identity or expression, age, ethnic or national origin, nationality, language, religion or belief, opinion, disability, state of health, sexual orientation, or other personal reasons.

We acknowledge the impact of imposter syndrome during job search, especially for underrepresented groups. If you’re interested in the position and believe that you have the potential to excel in it, we encourage you to apply.
