About the role

GenifySoft is looking for a Senior Full-Stack Developer to help us design, build, and ship production-grade products for clients across Europe and beyond. You will work closely with product owners, designers, and QA engineers in an agile studio environment where quality, clarity, and maintainability matter.

In this role you will own features from technical design through deployment. That includes API design, database modelling, frontend architecture, automated testing, and collaboration on DevOps practices. You should be comfortable making pragmatic trade-offs while keeping long-term scalability in mind.

We value engineers who communicate well, mentor others, and take pride in clean code. If you enjoy working across the stack and want to influence architecture on meaningful client projects, we would like to hear from you.

Responsibilities

  • Design and implement full-stack features across React/Next.js frontends and Node.js or .NET backends
  • Collaborate with designers and PMs to refine scope, estimates, and delivery milestones
  • Review pull requests, mentor mid-level developers, and raise engineering standards
  • Build RESTful and event-driven integrations with third-party services and cloud platforms
  • Write unit and integration tests; contribute to CI/CD pipelines and deployment workflows
  • Participate in architecture discussions for performance, security, observability, and scalability
  • Support production systems and contribute to incident resolution when needed

Requirements

  • 5+ years of professional software development experience
  • Strong proficiency in TypeScript, React, and Next.js
  • Solid backend experience with Node.js, .NET, or similar enterprise stacks
  • Experience with relational databases (PostgreSQL/MySQL) and API design

Many roles are Stockholm-anchored or hybrid; some collaborations are remote-friendly. Each job posting lists location and work model clearly.

GenifySoft is a complete digital solutions company based in Stockholm, Sweden. We design and build custom software, web and mobile products, AI-powered systems, and growth marketing for ambitious businesses.

Yes. While our headquarters is in Stockholm, we deliver projects for clients across Europe and globally using agile remote collaboration, clear documentation, and regular demos.

We work with modern stacks including React, Next.js, TypeScript, .NET, Node.js, Flutter, React Native, Azure, AWS, PostgreSQL, MySQL, and AI platforms such as OpenAI and Semantic Kernel - chosen to fit your product and team.

MVPs often land in 8–16 weeks depending on complexity. Larger platforms may run in phases. We define milestones upfront so you see working software early and can adjust scope with confidence.

Yes. We offer post-launch support, monitoring, feature iterations, performance improvements, and SLA-based care so your product stays secure and reliable as usage grows.

Absolutely. We can sign a mutual NDA before you share proprietary ideas, data models, or business plans. Mention this when you contact us and we will send our standard agreement.

We price based on scope - fixed-price for well-defined deliveries, or time-and-materials for evolving products. Use our price calculator for a rough estimate, then refine with a discovery call.

You get senior engineering and design focus without enterprise bureaucracy - direct communication, transparent delivery, and ownership of architecture decisions that scale with your business.

Custom software development means building applications tailored to your workflows, data, and users - instead of forcing your business into a one-size-fits-all product. GenifySoft designs, builds, and ships software that fits how you operate.

Choose custom software when off-the-shelf tools create workarounds, lack critical integrations, or become a competitive bottleneck. If your processes are unique or you need ownership of IP and roadmap, custom builds usually pay off.

Yes. We build responsive web apps, admin portals, customer dashboards, and secure REST/GraphQL APIs with authentication, role-based access, and cloud deployment.

We assess legacy platforms, plan phased migrations, and rebuild or wrap old systems with modern APIs so you reduce risk while improving UX, security, and maintainability.

We build generative AI features, conversational agents, LLM API integrations, RAG knowledge assistants, and NLP pipelines tailored to your data, compliance needs, and product UX.

Yes. We integrate OpenAI, Anthropic, Azure OpenAI, and similar providers with secure keys, rate limiting, prompt design, evaluation, and production monitoring.

Conversational AI powers chatbots and voice assistants that answer questions, qualify leads, or automate support. It is valuable when you have high support volume or want 24/7 guided self-service.

We offer SEO, pay-per-click advertising, social media marketing, and email marketing - either as standalone campaigns or as an integrated growth program aligned with your product roadmap.
