Software Engineer (Full-Stack)

About the Role:

We are building and operating several web-based SaaS products and internal tools for our clients.

Some of these products are built from scratch, and others are based on existing/white-label platforms and CRMs that we customize and integrate into a unified experience.

We are looking for a Full-Stack Software Engineer who can:

• Design and build web applications and APIs.
• Integrate and connect multiple systems and platforms.
• Occasionally extend and customize existing SaaS / white-label solutions.
• Help us turn business requirements into reliable, scalable software.

You will work closely with the founder/product owner and will have a big impact on the technical direction of our products.

Key Responsibilities:

• Design, develop, and maintain web applications (frontend + backend).
• Build and maintain REST APIs and services to connect multiple systems together.
• Integrate with 3rd-party platforms (CRMs, marketing tools, payment gateways, etc.).
• Customize and extend existing SaaS / white-label/off-the-shelf platforms when needed.
• Implement and maintain data models, business logic, and background jobs.
• Ensure applications are secure, performant, and maintainable.
• Work with the founder/product owner to:
• Understand business requirements
• Propose technical solutions
• Estimate and plan features
• Write clean, well-structured, documented code and follow good Git practices.
• Collaborate on basic DevOps tasks (deployments, environments, monitoring) with the team or 3rd-party providers.

Requirements:

• 4+ years of professional experience as a Software Engineer / Full-Stack Developer.
• Strong experience with modern frontend development, using:
• JavaScript or TypeScript
• A frontend framework such as React, Vue, or similar.
• Solid experience with backend development using one of:
• Node.js (Express / NestJS / similar)
• or PHP (Laravel / similar)
• or another modern backend framework (e.g. Django, Ruby on Rails, etc.).
• Good understanding of:
• REST APIs (building and consuming)
• Webhooks
• Authentication/authorization (sessions, tokens, JWT, etc.)
• Experience working with relational databases (PostgreSQL or MySQL).
• Comfortable working on both frontend and backend and taking ownership of complete features.
• Able to work in a startup / fast-paced environment:
• Self-driven
• Problem-solver
• Can work with limited specs and refine them with the business team.
• Good communication skills in English (for documentation, APIs, and tools).

Nice To Have:

(Not required, but a big plus)

• Experience with SaaS products (multi-tenant, subscriptions, dashboards, etc.).
• Experience with CRMs / marketing automation/analytics tools.
• Experience integrating multiple platforms into one interface (single dashboard / unified login).
• Familiarity with white-label platforms (e.g. GoHighLevel or similar tools), or customizing existing systems.
• Basic DevOps knowledge:
• Docker
• CI/CD pipelines
• Cloud providers (AWS, GCP, DigitalOcean, Hetzner, etc.).
• Interest in UI/UX and improving the user experience (even if not a designer).
