Fullstack Developer with System Integration Focus Wanted

Software Developer – Secure Systems & Backend Engineering

Location: Lund, Sweden | On-site | Security Clearance Required

At Asperiq, we build secure communication systems designed to protect sensitive data in critical environments. Now, we’re looking for a backend-oriented software developer to join our cross-functional team and help shape the next generation of our IP-VPN solution—built with Go, powered by event sourcing, and infused with cryptography.

You’ll work at the intersection of system-level programming, secure communication, and modern backend development. If you enjoy solving hard problems with a curious and methodical mindset, this is your opportunity to make a real impact.

What you’ll be doing

You’ll join our core development team and work on both our current platform and future cryptographic products. Your responsibilities will include:

• Building the backbone of our IP-VPN platform using Go and NATS Jetstream.
• Implementing messaging pipelines using MQTT or similar technologies.
• Applying event sourcing principles to ensure traceability and auditability in critical systems.
• Contributing to our web interface, primarily focusing on backend integration (React + Mantine).
• Participating in agile team rituals like stand-ups and planning meetings, and being actively involved in technical decision-making.
• Writing and maintaining automated unit and integration tests using Jenkins for continuous improvement.
• Collaborating across disciplines—from embedded hardware engineers to product managers—to deliver robust and secure solutions.

What we’re looking for

Required experience:

• 3+ years as a backend developer (ideally in a product company)
• Proficiency in Go (Golang)
• Hands-on experience with NATS Jetstream and MQTT (or similar messaging systems)

Additional skills we appreciate:

• Experience with event sourcing
• Familiarity with React and Mantine (for frontend-facing integration work)
• Knowledge of Gerrit, GitLab, and Jenkins
• Confidence working in Linux environments (Yocto experience is a plus)
• Experience with embedded development
• Understanding of networking principles and system-level architecture

What we value in you

• You’re adaptable and open to exploring new technical areas
• You enjoy complex challenges and take a structured approach to solving them
• You’re curious, continuously learning, and eager to improve both product and process
• You document well and communicate clearly—both in code and conversations
• You pay attention to detail without losing sight of delivery goals

What we offer

• A chance to work on mission-critical secure communication systems
• A collaborative team where your input matters and your work has visible impact
• A mix of deep technical work and product-level influence
• A flat organization that values learning, transparency, and continuous improvement
• An onboarding program and dedicated mentor to support your transition

Practical details

• Location: Finngatan 8, Lund, Sweden
• Clearance: This is a security-classified role that requires Swedish citizenship
