Job Description

Full-Stack Developer building a SaaS product for AI automation in accounting. Engage in full-stack development with autonomy and entrepreneurial spirit.

Responsibilities:

  • Build a real SaaS from scratch: full-stack development (front/back), architecture, performance optimization, security, and scalability.
  • Integrate and leverage advanced AI tools: OpenAI, Anthropic, Mistral, specialized LLMs, embeddings, prompt engineering, autonomous agents, etc.
  • Create complex API pipelines: multi-API calls (Google, Notion, WhatsApp, Pennylane, accounting platforms…), webhooks, authentication, and real-time event handling.
  • Manage and optimize databases: clean schema design, performant queries, relationships, indexing, and migrations.
  • Implement analytical computations and business rules: data extraction, automated analysis, scoring, anomaly detection, and recommendation generation.
  • Prototype very quickly: build, test, iterate, discard, and repeat when necessary.
  • Participate in all technical decisions: stack selection, product roadmap, technical trade-offs, and prioritization.
  • Work with full autonomy: understand a business problem, propose a solution, implement it, and ship it.
  • Adopt an entrepreneurial mindset: be proactive, take initiative, challenge choices, and prioritize product impact above all.

Requirements:

  • Proficient in JavaScript/TypeScript, ideally with Next.js, Node.js, or equivalent.
  • Strong understanding of APIs.
  • Able to analyze a problem, propose a solution, and take action.
  • Experience with personal projects, school projects, or side projects.
  • Autonomous, reliable, and a fast learner.
  • Genuine desire to commit to a long-term project.

Benefits:

  • Monthly fixed salary + variable pay per mission (you earn more by producing).
  • Direct involvement in building an AI SaaS in an untapped market.
  • Access to an ultra-flexible work environment (flexible hours, remote work, schedule compatible with studies).
  • Join the project very early (huge leverage on your future role in the company).
  • Rapid skill growth: AI, automation, SaaS, scalable architecture, APIs, modern development practices.
  • Real startup approach: no bullshit—you see the impact of your code immediately.
  • Opportunity to grow into a key position (CTO / Lead Developer depending on ambition).
