Careers at Sunly


Last updated on Feb 26, 2026 | Report an issue

You will join Sunly's IT team and coordinate information security across the organisation. You will bring together existing practices, systems and external partners to ensure that information security is handled consistently in day-to-day work across the Baltics and Poland.

What you will work on

  • Developing and maintaining information security policies and procedures
  • Coordinating day-to-day activities with an external security partner and a 24/7 Security Operations Centre (SOC)
  • Managing security incidents, risk assessments and follow-up actions
  • Lead the ISO/IEC 27001 certification initiative
  • Supporting and guiding employees on information security best practices
  • Working closely with IT and other teams to integrate security into systems and projects
  • Managing access rights and reviewing security-related configurations and changes
  • Supporting compliance with relevant standards and regulations, including NIS2 and E-ITS

What describes you

  • Proven experience in information security and risk management
  • Knowledge of information security standards and regulatory requirements, such as NIS2 and E-ITS
  • Ability to explain complex security topics clearly to non-technical colleagues and stakeholders
  • A structured and proactive way of working, with the ability to adapt in a fast-paced environment
  • Hands-on experience with tools such as SIEM, vulnerability management, endpoint protection and log management solutions
  • Genuine interest in renewable energy and an eagerness to use innovation and AI

What we offer

  • Support for your wellbeing, inside and outside work - a quarterly sports allowance via Stebby, comprehensive employer-provided health insurance (including dental care and specialist visits), and access to mental health counselling and coaching via siffi.com
  • Time to rest and reset - 28 working days of annual leave, counted only in working days and usable flexibly, plus additional paid days off, including health days and leave for important life events
  • Room to grow professionally - meaningful, hands-on challenges and a dedicated training budget for courses, certifications, and conferences, alongside internal learning opportunities to support your development
  • Flexible hybrid work - we work in a hybrid way, with no fixed rules on office days. You are trusted to balance remote work with time in the office, and while much can be done remotely, a lot happens in the office and being there regularly makes collaboration easier
  • Work that contributes to the energy transition - you will be part of a team building and scaling renewable energy across the region, working on services that support a more sustainable energy system

If you are excited about contributing to the renewable energy sector, we would love to hear from you! We review applications on an ongoing basis, so we encourage you to apply as soon as possible.
