Full Stack Engineer (.NET + Angular)

Full Stack Engineer (.NET + Angular)

Kaunas, Lithuania (Hybrid)

Overview

GLDS is US-based product company building mission-critical software that powers billing, provisioning, and operations for broadband providers across North America - systems that directly impact real customers and revenue.

We are building BroadHub.NEXT— the next generation of our platform. This is not a greenfield project. This is a live, revenue-critical system evolving into a modern architecture.

You will be working on:

• A multi-tenant platform (200+ deployments) with strict isolation requirements
• High-volume transactional systems (billing, payments, provisioning)
• Real-time and asynchronous workflows (APIs, webhooks, external integrations)
• Modernization of a mature platform into a scalable, service-oriented architecture

We are looking for engineers who think in systems, understand trade-offs, and take ownership.

Tech Stack (Current & Evolving)

• Backend: .NET (ASP.NET Core), REST APIs
• Frontend: Angular, Kendo UI
• Data: SQL (high-volume, performance-critical workloads)
• Integrations: APIs, webhooks, external systems
• Infrastructure: Docker (Kubernetes exposure is a plus)

What You’ll Do

• Own design and development of core system components
• Build scalable backend services using .NET (ASP.NET Core)
• Develop data-intensive Angular UI tightly coupled with backend workflows
• Drive architecture decisions and challenge existing approaches
• Design and implement reliable integrations (payments, e-signature, external systems)
• Solve performance challenges across large datasets, high-throughput workflows, and time-sensitive operations
• Work directly with product, QA, and engineering leadership on production-critical issues
• Mentor engineers and contribute to engineering standards and practices

What We’re Looking For

• Strong experience with:
• .NET / C# (ASP.NET Core, REST APIs)
• Angular (or similar SPA frameworks)
• SQL databases, including performance tuning
• Work directly with US-based product teams and real customers
• Experience building and evolving complex, long-lived systems
• Ability to design systems and make clear trade-offs (performance vs. complexity vs. scalability)
• Strong debugging skills in production environments
• Comfortable working with ambiguous requirements and evolving systems
• Experience mentoring and participating in code reviews
• Actively uses AI tools to accelerate development and problem-solving — with critical judgment
• EU citizenship (or legal right to work in the EU)
• Strong English communication skills

Nice to Have

• Experience with multi-tenant systems
• Knowledge of integration patterns (webhooks, idempotency, retry strategies)
• Experience with Docker / Kubernetes
• Familiarity with CI/CD pipelines
• Understanding of security and performance best practices

This Role Is NOT

• A pure frontend/UI position
• A ticket-driven implementation role
• A greenfield project without real-world constraints

What We Offer

• Opportunity to shape a next-generation platform (BH.Next)
• Direct impact on architecture and technical direction
• Work on real production systems with real customers
• Work alongside senior engineers experienced in large-scale, production systems
• Collaborative, experienced engineering team
• Hybrid work environment in Kaunas
• Competitive compensation
• Long-term, product-focused development

Compensation

We offer a competitive compensation package aligned with senior-level engineers in Kaunas, based on experience, ownership, and system design capability.

Typical range: €3,500 – €6,000 gross/month

Final offer depends on:

• Depth of system design experience
• Ability to operate in production-critical environments
• Ownership and impact demonstrated in previous roles

We are open to top-of-market offers for candidates who demonstrate strong technical leadership and ownership.

Compensation may include:

• Base salary
• Performance-based bonus

We focus on long-term product development, not short-term project work.

Why Join Now

We are at a stage where core architectural decisions are actively being defined. This is a chance to influence how the platform is built — not just implement it.
