Sales Coordinator, Defence & Security

Reaktor’s Defence & Security business is expanding into international product sales — and we’re looking for a curious and driven junior sales talent to join us in Helsinki.

Are you looking to take your next step in sales and business development? Do you want to be part of growing a new international business initiative in the field of Defence & Security? Are you curious to experience working in a low hierarchy and autonomous environment with a team that values teamwork, agility and continuous learning? If yes, you might just be what we're looking for!

Your role:

This is an exciting opportunity for a junior level talent to grow as a sales professional while helping us shape the future of our international product business. You will play a key role in supporting operational sales processes - from identifying opportunities to helping shape proposals and materials that make an impact. Working closely with experienced team members, you’ll learn how to navigate the unique DefSec market, collaborate with clients and partners, and ensure our sales operations run smoothly.

Your daily responsibilities:

• Take charge of operational tasks that keep our sales efforts running smoothly.

• Support sales processes and prepare sales materials, contracts, bid documents, and other export-related documentation.

• Develop impactful presentations, reference decks, and solution descriptions.

• Discover new opportunities, conduct lead generation and research on potential markets.

• Participate in client meetings, contribute in creating compelling proposals and monitor procurement portals for new opportunities.

• Engage with clients, handling daily communications and fostering strong relationships.

• Collaborate with partners and subcontractors to strengthen sales efforts.

To thrive in this position, you’ll need:

• 2-4+ years of experience in leading or supporting sales processes in the field of digital products or services.

• A keen eye for detail and the ability to craft clear, compelling, and well-structured sales materials.

• Good project management skills with the ability to juggle multiple priorities.

• Strong communication and collaboration skills – you thrive in a team-oriented environment but can also work independently, taking initiative and driving things forward.

• A goal-driven mindset combined with curiosity to learn and grow in the world of sales.

• Openness to travel for client engagements when needed.

• Fluency in Finnish and English (both written and spoken).

• Finnish citizenship is required due to client and security regulations, and the selected candidate must successfully pass a security clearance process upon hiring.

• This is a hybrid role – on-site presence (3–4 days per week) is required as part of our business operations.

Nice-to-have skills:

• A proven track record of being part of the whole sales cycle and engaging directly with clients.

• Experience with public sector tendering processes.

• Background in the DefSec sector.

• Experience in software or product sales.

• Strong presentation skills.

Why join us?

While working at Reaktor, we’ll provide you with:

• Exciting, purpose-driven work in a high-impact industry.

• An opportunity to grow as a professional, helping you develop your skills further through guidance and/or courses, and giving you the opportunity to explore your career interests.

• Autonomy and ownership over your work, giving you the power to make the changes and decisions that are needed to make an impact.

• A community with as much support as your heart desires.

• A team that’s not only experienced but considerate as well – they all want you to succeed.

• 300+ hobby clubs, from winter swimming and running to knitting and archery, that bring people together outside of (and sometimes inside) office hours. Many of these are supported by Reaktor.
