Full Stack Engineer

Senior Full stack Engineer – B2B SaaS (New Platform Build)

We’re working with a profitable, product-led SaaS company in the B2B logistics space that is entering a major “2.0” growth phase. The business has thousands of active customers, strong organic revenue, and long-standing partnerships with major international shipping and freight providers.

They are now building a brand-new platform from scratch, scheduled to launch later this year, and have paused feature development on their existing (already profitable) system to fully focus on the new build. This is a rare opportunity to join an early-stage platform rebuild within a financially stable, mature company.

The Role

We’re looking for hands-on Senior Full stack Engineers who enjoy building, owning, and scaling real products. You’ll work closely with product, UX, QA, and fellow engineers, taking responsibility across backend services, APIs, and frontend delivery.

The product is backend-heavy, but full stack capability is essential.

What You’ll Be Doing

• Playing a key role in designing and building a brand-new SaaS platform
• Developing scalable backend services using TypeScript and Node.js
• Designing and implementing REST APIs for core product functionality
• Contributing to frontend development using modern frameworks
• Collaborating in cross-functional product teams
• Writing automated tests to ensure performance, reliability, and maintainability
• Taking part in technical discussions and influencing engineering best practices
• Working in a fast-paced, pragmatic, delivery-focused environment

Product Teams

You’ll join one of several product-focused squads, such as:

• Shipment & Carrier Systems (booking, pricing, carrier integrations)
• Integrations & Extensions (e-commerce platforms, ERPs, customer systems)
• Frontend & User Access
• Payments, Pricing & Billing

Each team is small, autonomous, and ownership-driven.

What We’re Looking For

• ~7+ years professional software development experience
• Strong experience with JavaScript / TypeScript (5+ years)
• Solid Node.js experience (Express or similar)
• Experience building and consuming REST APIs
• Cloud experience (preferably AWS)
• Experience with at least one modern frontend framework (React, Vue, Angular, Svelte)
• Experience working with SQL and NoSQL databases

Nice to have:

• CI/CD, Docker, Infrastructure-as-Code (Terraform, Pulumi, etc.)
• Experience building scalable, secure systems
• Some DevOps / infrastructure exposure

The Kind of Engineer They Want

• Self-starting, high-pace, delivery-focused
• Comfortable taking ownership and making decisions
• Someone who can reduce load on tech leads, not increase it
• Pragmatic builders who enjoy shipping features and improving systems
• Scale-up / product mindset over corporate bureaucracy

They value impact and pace over years on paper a strong, driven engineer with ~5–7 years in the right environments will outperform someone with 20 years who needs hand-holding.

Location & Working Model

• Offices in Stockholm and Jönköping
• Hybrid preferred
• Open to remote within Sweden for the right person
• English-speaking environment

Package

• Permanent role
• Highly Competitive Salary
• Performance-based bonus (company-revenue dependent)
• Standard pension with employer top-up
• Wellness allowance (~4,000 SEK/year)
• 5 weeks’ vacation (negotiable)

Why This Role?

• Very stable company with organic growth
• Profitable product, not VC-dependent
• Brand-new platform build with huge technical impact
• High ownership, autonomy, and trust
• Tons of feature development and real engineering challenges
