Wisor.AI - Backend Team Lead

Wisor.AI, an early-stage and well-funded startup, is now looking for an experienced and passionate Backend Team Leader to join and lead a growing and dynamic engineering team within our R&D department.

About us:

Wisor.AI is revolutionizing the way shipping companies operate—replacing outdated manual work with smart, AI-powered tools that bring them into the future of global trade. We offer an AI-based pricing optimization and shipment automation web platform designed to eliminate inefficiencies regarding freight pricing, placement, and shipping in general.

AI Driven development - At Wisor.AI, Our development team continuously works to adapt to the rapidly evolving best practices in AI-driven development. Our R&D teams push, embrace, and actively encourage the use of coding assistants. We’re always improving how we work—adopting modern development practices that help us move faster, write better code, and collaborate more effectively. We believe that the way we develop products is going to change dramatically and rapidly in the near future and we, as a team, need to invest our time to learn what is out there, but also to create the future best practices of software development, especially in areas that we believe that are impactful but have not yet been advanced enough. Some examples - While personal development best practices are advancing fast, team best practices are maturing rather slowly but are critical in many aspects. Advanced code review capabilities - the modern coding cycle involves reviewing code on a much larger scale than ever before, and therefore fast but reliable code reviews become exceptionally important. Fast and comprehensive automated QA cycles follow a similar pattern - where the ability of the coding agents to complete a task and test its functionality before handing it over back to the developer has an enormous impact. These are some of the things that we expect to focus on as a development team in 2026.

This is your chance to join early, make a real impact, and grow with a team that’s shaping the future of global logistics.

Excellent understanding of database concepts and structure, with hands-on experience in various database technologies (MongoDB, PostgreSQL, Neptune, S3).
Proven ability to simplify complex technical ideas and communicate them effectively to both technical and non-technical stakeholders.
Strong startup mindset: Demonstrating exceptional ownership, responsibility, and initiative. Possessing a customer-first mentality, striving for wide product understanding, detail orientation, and critical thinking. Capable of reasoning tradeoffs of different solutions (good vs. great vs. perfect) and not afraid to get your hands dirty to do what needs to be done.
Deep understanding and practical experience with software development methodologies, such as Agile and Scrum.
Exceptional problem-solving skills and a strategic approach to technical challenges.
Extensive familiarity with micro-services architectures, and ideally, experience seeing them in operation at a global scale.
Demonstrated ability to inspire, motivate, and build a team.

Advantages:

A passion for utilizing AI to dramatically increase development efficiency and foster its adoption within the team.
Prior experience in a fast-paced startup environment.
Strong analytical background – from academic studies (e.g., CS, mathematics, physics, EE) or previous work experience tackling challenging, complex problems.
