About the role

The company and our mission:
Zartis is a global AI transformation and technology consulting partner where talented engineers and technologists work on cutting edge innovation. We partner with ambitious organizations to design, build, and scale technology solutions that deliver real impact.
Our teams bring deep expertise in AI driven platforms, secure API architectures, and cloud native engineering. You will work on meaningful projects that accelerate the adoption of advanced technologies, from strategy and discovery through to full product delivery, helping turn complex challenges into measurable outcomes.
With engineering hubs across EMEA and LATAM, and long term partnerships in financial services, healthcare and life sciences, and energy and climate, we offer opportunities to work on projects that truly matter. 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.
The project:
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.
