Full-Stack Developer (.NET Core)

Why this role matters

Lab Thread is a fast-growing, engineering-driven Biotech SaaS company building modern software that unifies bioinformatics, automation, and cloud technology to eliminate lab chaos and accelerate discovery. Founded in 2023, we design a next-generation LIMS/ELN platform designed specifically for biologists and the needs of small and mid-sized biotech teams.

As a Full-Stack Developer, you will be a core contributor to the design, development, and deployment of our platform’s features. Your work will drive innovations that empower scientists worldwide — impact that goes far beyond software, enabling faster drug development and breakthroughs in human health and sustainability.

‍

What you will do

As our Full-Stack Developer, you will own features end-to-end — from database schema to API design to user interface. This role is not about implementing tickets — it is about building robust, scalable solutions while working directly with our engineering, QA and product teams. You will:

• Design and develop new features for our platform, from concept to deployment.
• Write clean, maintainable, and efficient code for both front-end and back-end components.
• Build and maintain scalable APIs and services using the .NET framework.
• Work with relational databases to manage and optimize data storage.
• Participate in code reviews and contribute to the continuous improvement of our development processes.
• Troubleshoot and resolve complex technical issues and bugs.

You will have the autonomy to propose solutions, introduce improvements, and influence the technical direction of the platform.

About you

We are looking for a passionate and skilled Full-Stack Developer eager to build next-generation software for life-science research labs — someone motivated by solving real-world workflow fragmentation and delivering strong, growth-ready solutions.

You think in systems, understand how components interact, and take ownership of quality from idea to production. You communicate clearly in both Bulgarian and English with developers and non-technical stakeholders alike, adapt quickly to new domains, and proactively improve code rather than wait for direction.

Must-haves:

• 3+ years in full-stack software development.
• Strong hands-on experience with .NET Framework, .NET Core, and C#.
• Proficiency with React, Next.js, TypeScript, and JavaScript, as well as styling frameworks like TailwindCSS.
• Solid experience with SQL Server, Redis Cache, and Entity Framework, incl. database design and performance optimization.
• Proven experience in building and consuming RESTful APIs.
• Familiarity with Microsoft Azure, Docker, and Bitbucket Pipelines.
• Knowledge of architectural patterns like Domain-Driven Design and Clean Architecture.
• Familiarity with Git and Agile/Scrum methodologies.

Nice-to-haves:

• Experience with Scientific Software or the Life Sciences industry.
• Experience in applying AI/ML models to solve real-world problems.
• Familiarity with Micro Front-end architecture and performance optimization.
• Experience with OpenID Connect and NextAuth.js.
