Sales Intern (B2B Sales & Business Development)

Sales Intern | B2B Sales & Business Development

Stockholm | Hybrid | Formal educational internship or Arbetsförmedlingen arbetspraktik only

Sustainium AB develops fibre-based food packaging solutions for international food and beverage businesses. We are seeking a curious, analytical intern to gain supervised, practical experience in B2B sales, lead generation and business development.

Mandatory eligibility: one of two routes

You must qualify through ONE of the following two arrangements. These are the only internship routes we accept:

1. Educational internship (LIA/YH or university/other recognised education): Your current educational programme requires or formally approves a practical internship, and your school can confirm the placement, duration, supervision and applicable documentation. Simply being enrolled as a student is not sufficient.
2. Arbetsförmedlingen arbetspraktik: You are registered with Arbetsförmedlingen and may qualify for an arbetspraktik placement, subject to its individual assessment and formal approval before starting. Being unemployed or under 25 does not automatically establish eligibility.

We cannot accept informal, independent or self-arranged unpaid internships outside these two routes. Applicants must identify their route in the application form. Eligibility and any required agreements will be verified before a placement is confirmed.

What you will learn and do

• Research and identify prospective B2B customers and relevant decision-makers in international markets.
• Learn to qualify accounts and support structured prospecting and market mapping.
• Develop skills in HubSpot CRM, LinkedIn Sales Navigator, research tools and AI-assisted sales workflows.
• Support preparation of outreach, customer briefs, presentations and sales materials.
• Participate in supervised commercial activities, coaching and regular feedback sessions.

Who we are looking for

• Interest in international B2B sales, business development and commercial research.
• Strong organisation, attention to detail, analytical curiosity and English communication skills.
• Confidence using digital tools and willingness to learn. Previous sales experience is not required.
• Ability to attend our Stockholm office as agreed within a hybrid arrangement.

What we offer

Structured learning objectives, supervision by experienced commercial colleagues, practical exposure to international sales and sustainable packaging, and regular feedback. Future employment may be considered separately depending on business needs.

Location, duration and conditions

Stockholm, hybrid with agreed office attendance. Dates, duration and working hours must fit the educational programme or approved Arbetsförmedlingen arrangement; we generally aim for approximately 3–6 months where permitted. This is a formal internship placement, not a salaried employment offer. Applicable programme compensation, insurance and placement conditions follow the relevant educational or Arbetsförmedlingen arrangement.

Before applying: Please confirm that you meet at least one of the two routes above. Applicants who meet neither route cannot proceed.
