Posted on Sunday, July 7, 2024
As a Full-Stack ML Engineer at Donna, you'll be a vital part of our team, working together to build Donna, our perfect AI-sales assistant for sales reps. Donna empowers them to focus on what they do best - selling.

Expect to navigate a wide range of challenges including developing a scalable LLM framework, fine-tuning and personalising prompt engineering, orchestrating multiple AI agents, and implementing advanced RAG systems. Your goal will be to craft the optimal user experience with our LLMs.

You’ll join Donna & the team as one of the first hires. This means you’ll have the opportunity to be part of an early-stage start-up and to learn from experienced serial entrepreneurs.

If you're ready to embark on an exciting journey from the early days and make a significant impact in a growing team with global ambitions, Donna is the place for you!


A non-exhaustive list of features we could use your help with:

  • Leveraging best practices and industry-leading tools and technologies to solve real-life problems with LLM solutions.
  • Fine-tuning and optimising prompting techniques (like prompt-chaining) to improve the accuracy and relevance of responses for our users.
  • Integrating and synthesising a massive amount of contextual data (CRM data, call recordings, emails) to enrich the LLM context and provide more accurate and personalised outputs.
  • Developing algorithms in multilingual conversational systems.
  • Developing and enhancing RAG systems to ensure high-quality and contextually appropriate responses.
  • Ensuring the outputs of our LLMs maintain a high standard of quality, accuracy, and relevance.

We believe in shipping fast to gather feedback quickly from our customers. We focus more on building the right product than building the product right.

We like to keep things simple, so we leverage as much as possible the services offered by key vendors.

You’ll report directly to our co-founder & CTO, but you’ll work together with other departments (and customers) in detailing the requirements of features and make trade-offs together in order to maximise value while minimising complexity.


  • We’re looking for someone passionate about LLMs, with working experience and a strong desire to become an expert in the field.
  • You have at least 3 years of experience as a Full Stack, Software, or Data engineer, or in a similar position.
  • You are a perfectionist who is not afraid to critically evaluate data and results.
  • You have strong problem-solving abilities and a go-getter mentality that embraces challenges.
  • You’re able to break down big initiatives into small tasks, allowing for re-prioritization as important opportunities arise.
  • Personal growth is important to you, and you have the ambition to thrive in a start-up culture.
  • Collaboration is key for us, so we’re looking for individuals who are fun to work with, have a lot of expertise, and are open to other people’s opinions.
  • We have global ambitions, so fluency in English is a must.
  • Ability to work with us in the Ghent office; this is not a remote position.
  • Having affinity with sales is a plus.


  • You will be able to work with cutting-edge AI and state-of-the-art technology that will revolutionise the world of SalesTech! 😎
  • As one of the first hires at Donna, you’ll have a front-row seat to witness our growth. 🚀
  • Become a part of the Ghent tech ecosystem and a member of the StarApps ecosystem. 💪

Along with these awesome perks, we offer a competitive salary with the following benefits:

  • Macbook Pro 💻
  • Healthcare benefits plan 🏥
  • Meal vouchers 🍴
  • Annual company retreat 🎊
  • Free office snacks 🍰
  • Team drinks and events 🍺🎉
