Vacant job

Seriline is a Swedish tech company specializing in identity and access management (IAM). We develop our own software, web solutions, and security systems that control who has access to what – systems, premises, data. Our customers are organizations with high security requirements where accuracy and traceability are business-critical.

With stable finances and long-term investments in both products and personnel, we offer an environment where you have technical influence, short decision-making paths, and the opportunity to help shape the next steps.

We are looking for a full-stack developer with strong JavaScript skills for our Stockholm office. You will be part of a close-knit team of ten people who develop and maintain platforms within IAM and visitor management.

The role spans the entire development chain – from design and architecture, through development and testing, to deployment and support. You will work with both frontend and backend in a modern JavaScript-based stack.

We are an office-first company where work takes place from the office at Alviks Torg. Here, we prioritize close collaboration, quick decision-making, and an environment where it is encouraged to discuss technical solutions.

• Develop new features in our JavaScript-based platform

• Maintain and improve the existing codebase

• Participate in design, architecture, and technical decisions

• Work with integrations and APIs to external services

• Implement the platform at customer sites or in a SaaS environment

• 3rd-line support with troubleshooting

Required:

• At least 3 years of work experience in development

• Strong skills in JavaScript and Node.js

• Experience with MongoDB or another NoSQL database

• Good knowledge of React

• You use AI tools as a natural part of your development work

• Experience with Git and established workflows

• Understanding of web security (OWASP Top 10)

• Bachelor's degree in a relevant field or equivalent experience

• Fluent in Swedish, both spoken and written

• Swedish citizenship (required for security clearance)

Preferred:

• API design (REST/GraphQL)

• OAuth2/OIDC, JWT, CORS/CSRF, CSP

• Experience with MeteorJS

• Skills in .NET/C#

• Experience in implementing or improving AI-supported workflows in development teams.

• Knowledge of Entra ID and Active Directory

• Experience with integrations against access control systems, RFID/NFC

• Experience as a Tech Lead or IT architect

You are proactive, willing to raise questions early, and enjoy taking responsibility. You like to discuss technical solutions and contribute ideas. With us, it is more important that you are curious and driven than that you know everything from day one.

• Own product development with direct impact on the end result

• Technical breadth: full-stack, integrations, security

• Experienced team with short decision-making paths

• Stable employer with long-term investments

• AI tools are a natural part of everyday life
