Here, you will not just build technology, you will drive business impact and grow your career alongside industry leaders.

We are looking for a Senior Software Engineer to work on a project in the Logistic industry.

Our teammates are talented people that come from a variety of backgrounds. We're committed to building an inclusive culture based on trust and innovation. You will be part of a distributed, cross-functional team at an exciting and exploratory stage of our client's AI initiative — helping to shape how AI is architected, integrated, and adopted across the organisation. We are looking for someone with strong architectural thinking and good communication skills, who is comfortable operating in ambiguous environments, contributing to evolving technical standards, and challenging ideas constructively — rather than simply executing predefined tasks.

What you will do:

• Design and build robust backend services using TypeScript and NestJS, integrating AI capabilities into existing and new product workflows
• Work with Prisma and AWS (or equivalent cloud infrastructure) to build scalable, production-grade systems
• Incorporate AI tooling and prompt engineering into development workflows, going beyond off-the-shelf tools to build purposeful, well-considered AI integrations
• Contribute to architectural decisions and technical standards as the team's AI approach continues to evolve
• Help shape how the organisation thinks about and adopts AI-assisted or spec-driven development practices
• Collaborate closely with stakeholders across engineering and product, operating effectively in an ambiguous and fast-moving environment.

What you will bring:

• Strong hands-on experience with TypeScript and NestJS in production environments
• Solid experience with Prisma and cloud infrastructure, particularly AWS or a comparable platform
• Genuine, practical experience building with AI tooling — this means working with models, integrating prompts into development workflows, and building AI-powered features; not simply using consumer AI products
• The ability to think architecturally and help shape solutions, rather than waiting for problems to be fully defined
• Comfort challenging ideas, proposing patterns, and contributing to technical standards discussions
• Strong communication skills and the confidence to be proactive, collaborative, and direct in a distributed team

Nice to have:

• Previous experience helping an organisation adopt AI-assisted or spec-driven development practices
• Familiarity with emerging AI development frameworks and orchestration patterns
• Experience working in early-stage or exploratory technical initiatives

What we offer:

• 100% Remote Work
• WFH allowance: Monthly payment as financial support for remote working.
• Career Growth: We have established a career development program accessible for all employees with a 360º feedback that will help us to guide you in your career progression.
• Training: For Tech training at Zartis, you have time allocated during the week at your disposal. You can request from a variety of options, such as online courses (from Pluralsight and Educative.io, for example), English classes, books, conferences, and events.
• Mentoring Program: You can become a mentor in Zartis or you can receive mentorship, or both.
• Zartis Wellbeing Hub (Kara Connect): A platform that provides sessions with a range of specialists, including mental health professionals, nutritionists, physiotherapists, fitness coaches, and webinars with such professionals as well.
• Multicultural working environment: We organize tech events, webinars, parties, and activities to do online team-building games and contests.
