At Cosylab, we build software and electronics that power some of the world’s most advanced scientific and medical systems — from particle accelerators and fusion reactors to innovative radiotherapy solutions. With our Treatment Product Software, we help organisations deliver safer, more efficient and more personalised patient treatments.

About the Role

We are looking for a Product Marketing Manager for Treatment Product Software to join our marketing team in Ljubljana. This is a mid-to-senior role, combining strategic ownership (positioning, GTM, market insight) with hands-on execution across content, collateral and campaigns.

If you enjoy turning complex technology into clear, customer-focused stories – and you enjoy owning both the strategy and the execution – this role might be a great fit.

Key Tasks and Responsibilities

• Own positioning and messaging: Define and sharpen the value proposition for our Treatment Product Software, ensuring our story is clear, compelling, and consistent across all channels.
• Lead go-to-market for launches and campaigns: Plan and execute product launches and marketing campaigns - define target segments and personas, craft messaging, and drive initiatives to reach relevant audiences (partner with Product and Sales to bring new capabilities to market).
• Enable sales & customer teams: Create and maintain the marketing and sales toolkit for medical software products – pitch decks, solution overviews, one-pagers, battlecards, demo narratives, and FAQs – and train sales and account managers on how to use them in real opportunities.
• Drive market & competitive intelligence: Continuously track the radiation oncology landscape, gather community and customer insights, and feed those insights back into messaging and the product roadmap.
• Cross-team collaboration: Work closely with Product Management, Sales, and the broader Marketing team to ensure our offering and narrative reflect customer needs and support our mission and business goals.

Required Qualifications and Skills

• 5–8 years of experience in B2B product marketing or a closely related role (e.g., solution/portfolio marketing) for software or complex technical products.
• A track record of:
• Developing value propositions and messaging
• Owning go-to-market plans for launches or major releases
• Creating sales and customer enablement collateral
• Strong communication skills in English – you can comfortably talk to engineers, medical physicists, and business stakeholders, and adapt the story to each.
• An analytical and curious approach: you like to understand the market, talk to customers, and base your recommendations on data and insight.
• A collaborative mindset and comfort working in cross-functional teams.

What we offer

• Employment contract for an indefinite period with a six-month probationary period.
• A work environment with flexible working hours and a hybrid work model.
• Plenty of personal and professional growth opportunities combined with a competitive and periodically updated salary tailored to your skills, experiences, and results.
• Interesting work full of challenges in an international working environment.
• Opportunities to work abroad.
• High-impact learning culture: regular in-house and external training sessions and a team of international professionals eager to help you grow.
• Many recreational after-work activities, additional health insurance (Specialists+), unlimited coffee, soft drinks, fruit, and other well-being goodies.
• Cosylab events (Teambuilding, New Year’s Party, Picnic… ).
• Casual atmosphere with friendly faces where you can completely “be yourself.”

You will fit perfectly if you share these values

• Think bold: We deliver exceptional solutions through courageous thinking, open communication, and the drive to continuously improve.
• Be modest: We set our egos aside in actively listening, respecting one another, and embracing the diversity of experience and perspective across the company.
• Work smart: We know we get more accomplished by working together, being accountable, focusing our efforts, and going the extra mile.
• Enjoy life: We prioritize balance and positivity, nurturing personal wellness and celebrating successes.
• Do good: We support one another and are passionate about solving difficult problems that ultimately help make the world a better place.
