Job Description

About the opportunity

We're looking for an experienced Software Developer to join us at the very beginning of building a new AI-powered SaaS platform for accounting firms.

Working closely with the Product Manager and founders, you'll play a key role in turning product ideas into scalable software. This is a unique opportunity to help shape both the technical architecture and the product itself from day one.

The platform is envisioned as the operating layer for modern accounting firms—a central hub connecting accountants, their clients, and the software they already use. By leveraging AI, workflow automation, and integrations with existing accounting systems, we're building a product that helps accounting firms operate more efficiently and deliver a better experience to their clients.

The product is backed by experienced founders and secured funding, with a strong focus on rapid execution and building an exceptional engineering culture from the ground up.

What you'll do:

• Design, build, and maintain a modern SaaS platform from the ground up

• Work closely with the Product Manager to translate customer needs into technical solutions

• Design and implement AI-powered workflows that automate operational processes for accounting firms

• Build and orchestrate AI agents capable of supporting complex business workflows

• Develop integrations with third-party accounting, payroll, and financial systems

• Design scalable APIs and backend services

• Contribute to architectural decisions and establish engineering best practices

• Prototype new AI capabilities and evaluate emerging technologies

• Collaborate with designers and product stakeholders throughout the development lifecycle

• Continuously improve performance, scalability, and reliability of the platform

We're looking for someone who has:

• 5+ years of software development experience

• Experience building modern web applications or SaaS platforms

• Strong backend development experience

• Experience designing scalable system architectures

• Experience building API-first applications and integrating third-party services

• Experience working in cloud environments

• Strong understanding of software engineering best practices

• Ability to work independently in a fast-moving startup environment

• Excellent communication skills in English

Nice to have:

• Experience building AI-powered applications

• Experience working with LLMs and AI agents

• Experience designing workflow automation platforms

• Experience with orchestration frameworks (LangGraph, CrewAI, AutoGen, Temporal, etc.)

• Experience integrating with accounting, ERP, payroll, or fintech systems

• Experience working in fintech or accounting technology

• Startup or early-stage product experience

• Experience with event-driven architectures

What you'll get:

• The opportunity to build a product from the ground up

• Direct collaboration with experienced founders

• Significant influence over technical architecture and engineering decisions

• The chance to build real-world AI applications that solve meaningful business problems

• A fast-moving environment with minimal bureaucracy

• Office based in Belgrade, working closely with the founding product team.

Why this role is different:

This isn't a role where you'll be implementing predefined tickets. You'll work alongside the Product Manager to explore problems, prototype solutions, and build a platform that combines AI, workflow automation, and integrations into a seamless experience for accounting firms.

If you enjoy building products from scratch, experimenting with AI, and creating software that fundamentally improves how businesses operate, we'd love to hear from you.
