Job description

Making life accessible

iLOQ is an international company headquartered in Finland that offers intelligent locking systems and total access management solutions. We provide secure and efficient access to buildings and facilities. Our mission is to make everyday life easier with a diverse range of safe and sustainable products for individual buildings, large real estate complexes and critical infrastructure sites.

We reinvented the lock. iLOQ's self-powered digital locking and mobile access solutions work without batteries or mechanical keys, something nobody thought was possible until we did it. But the lock is only half of the story.

Behind every iLOQ lock is iLOQ 5 Series+. iLOQ 5 Series + is our modern, cloud-based, AI-enabled software platform which powers access management for buildings and large real estate complexes across the world. Locks, keys, apps and cloud services are all working as one system: this is where hardware innovation meets serious software engineering. Scalable backend services, security-critical design and a platform that keeps evolving with new AI-driven capabilities.

We are now looking for a Senior Backend Developer to join our Software organization in Oulu. You will design, develop and maintain the secure, reliable and scalable backend services at the core of iLOQ 5 Series+. This is a role for an experienced software professional who enjoys solving complex problems, takes ownership beyond writing code and wants to influence both technical solutions and the way software is developed.

What you'll do

As a Senior Backend Developer, you will work as part of a cross-functional software team and contribute throughout the software lifecycle.

You will:

• Design, develop, test and maintain reliable, scalable backend services and APIs for our cloud-based platform

• Take end-to-end ownership of services from design and implementation to release, monitoring and continuous improvement

• Translate functional and non-functional requirements into practical technical solutions

• Explore and apply AI-assisted development tools in a secure and responsible way

• Review code and develop automated tests, supporting high standards for security, quality and maintainability, and contributing to efficient CI/CD practices

• Investigate and resolve complex technical issues

• Contribute to the modernization and continuous development of our software architecture

• Collaborating with Product Owners, Software Architects, Test Engineers and other stakeholders, share knowledge and support the development of colleagues

What you'll bring

To succeed in this role, we expect you to have:

• Relevant degree (Bachelor or Master)

• Several years of professional experience in backend software development, including designing and implementing APIs and backend services

• Strong skills in C# and .NET or comparable backend technologies

• Experience with cloud technologies, preferably AWS, and a solid understanding of microservice architectures and distributed systems

• Experience working with relational databases and data-driven applications

• Familiarity with automated testing, CI/CD and modern software development practices

• An understanding of software security, maintainability and operational reliability

• The ability to analyze complex problems and turn them into clear, sustainable solutions

• A proactive and collaborative working style with strong communication skills, including professional written and spoken English

We consider experience in the following areas an advantage:

• AWS services and cloud-native application development

• Event-driven architectures and asynchronous communication

• Service monitoring, logging and observability

• Secure software development or access management solutions

• High-availability or business-critical systems

• Working with software solutions that interact with physical products or devices

What you'll get

You will build products that end up in buildings all over the world and ease the everyday lives of our customers. You will have real responsibility and freedom to operate without big corporation bureaucracy. We ensure you’ll have room to grow professionally in a fast-growing international company.

We offer you a workplace within a collaborative and forward-thinking company culture, friendly and skilled colleagues, proper onboarding, and a solid benefits package: bonus program, full lunch benefit, extensive occupational health care with an annual dental check, life insurance, plus regular team and company events.

We are committed to fostering an inclusive workplace where diversity is valued and all employees are treated with respect. We encourage applicants from all backgrounds to apply and join us in promoting an inclusive and diverse workplace.
