Vaisala is a global leader in measurement instruments and intelligence helping industries, nations, people, and the planet to thrive.

This role offers a unique opportunity to apply your tax expertise in a fast-paced, global group, with broad international exposure and the chance to contribute to business decisions that drive the group's growth and success. Your work will have a tangible impact, while providing opportunities to further develop your professional expertise and career.

Numbers speak louder than words. The engagement (4.0/5) and leadership (4.0/5) indexes in our annual employee survey show that people like it here. Commitment to equality is a given, and we have zero gender-pay gap.

Leading performance, not location. Our culture is trust-based. We treasure face-to-face collaboration with our colleagues, but hybrid work and flexibility are the new norm for us.

What's your role?

You will be part of our Group Tax Team, which is part of the Finance & Control organization at Vaisala.

Moreover, you will also collaborate with external stakeholders such as external advisors and tax authorities. You will report to Head of Tax.

In this role you will:

• Develop Vaisala's indirect tax processes and controls in line with best practices and Vaisala's Tax Strategy.
• Advise on tax-efficient structures for sales, supply chain, as well as Vaisala strategic initiatives and new business models, including service-based and XaaS offerings, to support compliant and profitable international growth.
• Provide day-to-day tax support to the business and other stakeholders.
• Lead tax assessments for international project deliveries and new country operations, collaborating with external advisors as needed and coordinating the successful implementation of tax advice.
• Contribute to M&A transactions by supporting tax due diligence, structuring, and post-close integration.
• Plan and participate in change projects relating to indirect tax (such as ViDA).
• Serve as indirect tax expert for SAP S/4HANA system purposes.
• Strengthen tax awareness and capabilities across the organization by delivering training programs and developing internal guidance.
• Monitor legislative changes and assess their impacts on Vaisala.
• Manage tax audits.
• Prepare tax related disclosures to the Group's annual report, e.g. Vaisala's tax footprint.

What will you bring?

• Previous working experience in VAT and indirect taxation; experience in other fields of tax is considered an advantage.
• Good understanding of international tax laws and practices.
• Experience of managing work with external consultants and ability to interpret and apply advice relating to foreign tax systems.
• Good team working skills and willingness to take initiative and lead your own work in a fast-paced environment with multiple stakeholders and deadlines. Strong problem-solving skills, with a proactive approach to identifying practical solutions.
• Interest in achieving efficiency through AI and automation in tax operations.
• Excellent communication skills in English.
• Master's degree in law, accounting or business administration.
