Senior Full-Stack Engineer

US-based early-stage startup in the insurance domain operates as an aggregator platform that helps users find optimal insurance solutions across providers, while also developing a loss prevention direction through data and automation. The product is not legacy — it has been built from scratch by the CTO and is now entering a scaling phase. A key focus area is AI and automation — building workflows, integrating AI agents, and optimizing processes across the platform. Your mission will be to help scale both the product and the technical foundation as the CTO’s right-hand engineer.

Location: Remote
Working Hours: Partial overlap with US (Boston) — 3–4 hours

Your responsibilities will include:

• Hands-on coding and solving complex backend and full-stack challenges in a fast-paced startup environment.
• Lead and mentor 2–4 developers while continuing to write production code yourself.
• Build and maintain scalable backend services using Node.js.
• Design and implement architecture, workflows, automation, and AI-driven processes.
• Work with integrations, APIs, and data pipelines across multiple external insurance providers.
• Collaborate closely with the CTO (your direct manager) and the small core product team (5–6 people).
• Drive technical decisions, feature development, and product scaling.
• Improve and maintain code quality, including basic test coverage.
• Participate in building systems that optimize insurance selection and risk prevention.
  ‍

What we expect from you:

• 12–15+ years of professional software engineering experience.
• English: B2–C1 or higher (active communication with the US team is essential).
• Strong hands-on backend development with Node.js.
• Solid full-stack understanding, including React (or equivalent frontend frameworks).
• Multi-stack experience and a stack-agnostic mindset.
• Deep understanding of software architecture and system design.
• Real coding experience (you are a hands-on engineer, not only a leader).
• Ability to lead small teams (2–4 developers) and take ownership.
• Experience working with automation tools, workflows, or AI-related features (agents, LLMs, etc.) — strong plus.
• Good understanding of APIs, integrations, and data handling.
• Ability to work independently in a startup environment with minimal supervision and without strict processes or detailed specifications.
• Strong problem-solving skills, proactive mindset, leadership, and ownership.
• Basic understanding of testing (unit/integration).
  ‍

Nice to Have:

• Previous startup experience.
• Leadership and ownership in scaling products/technical teams.
• Hands-on experience with AI-powered products or LLMs.
• Familiarity with building or optimizing automation processes.

We offer:

• Work on an early-stage product with real impact in the insurance domain as a core team member.
• Opportunity to be the CTO’s right-hand engineer and shape both product and technical decisions.
• Hands-on experience with AI, automation, modern full-stack systems, and scaling from scratch.
• Fast-paced environment with minimal bureaucracy in a small distributed team (US + LatAm + Europe).
• 100% remote work, long-term core role.
