Job description

About the Role

You will be the hands‑on security specialist responsible for keeping our internal digital landscape secure — across systems, integrations, cloud environments, data flows, and our vendor ecosystem. This role reports into the CISO office, directly to the CISO & Compliance Manager.

You will combine security architecture thinking with practical execution: threat modeling, technical risk assessments, vendor due diligence, and governance work. You will partner closely with IT, Engineering, and Legal, acting as the internal security expert stakeholders turn to. You will also play a key role in how we secure our growing use of AI — an area that brings both significant opportunity and significant risk.

This is a high‑impact, cross‑functional role for someone energized by the full breadth of security work — from technical assessments to policy and standards.

What You Will Do

• Lead security assessments of systems, integrations, and data flows
• Conduct technical risk analyses for system implementations and vendor onboarding
• Perform threat modeling and security architecture reviews
• Define and implement security requirements for infrastructure and cloud environments
• Assess and manage third‑party and supplier security risks
• Evaluate and manage security risks related to AI systems and AI‑integrated products
• Maintain alignment with ISO 27001 and SOC 2 Type II; contribute to policies, standards, and guidelines
• Support incident investigations and act as a subject matter expert in audits
• Help establish security guardrails across identity, access, encryption, and integrations

What Will Help You Thrive

• 5+ years in cybersecurity, information security, IT risk, or security architecture
• Hands‑on experience with threat modeling, risk assessments, and vendor security reviews
• Strong technical foundation in cloud, networking, identity & access management, and system integrations
• Familiarity with ISO 27001 and SOC 2 Type II
• Awareness of AI security risks and how AI adoption changes the compliance and threat landscape
• Strong communication and stakeholder management skills — you work across IT, Engineering, and Legal
• Certifications such as CISSP, CISM, or CISA are a plus
• Degree in Computer Science, Engineering, or a related field

Who We're Looking For

You combine technical rigour with genuine people skills — comfortable owning a threat model one day and a policy document the next. You are pragmatic, hands‑on, and motivated by outcomes. You communicate clearly across audiences, thrive with broad responsibilities, and are proactive about improving both yourself and the way things are done.

Benefits

• Flexible hybrid setup — 3x a week at the office
• 33 days of paid time off – 30 vacation days plus 3 extra days to make sure you get the rest you deserve.
• Premium occupational pension – Our pension plan goes beyond ITP1, with higher employer contributions depending on your age and salary level.
• Generous wellness allowance – 5,000 SEK annually to support your health and wellbeing.
• Private healthcare insurance – Skip the waiting lines and get quick access to private medical care, including specialist consultations and treatments.
• Parental leave top‑up – We top up your parental leave so you receive up to 90% of your base salary for up to 6 months, helping you focus on your family without financial stress.
• Weekly treats – Fika one week, breakfast the next, because good food brings people together.
