Software Engineer (Mid/Senior)

First off, thank you for considering AIAIAI. Yes, we’re looking for a Full-stack web developer. And yes, there are plenty of other opportunities out there. If you’re exploring your options, you might be thinking about growth, creativity, a sense of purpose, or just a healthier work-life balance. We get it—everyone wants their own version of a “perfect fit.”

So here’s why you might consider AIAIAI:

We’re an early-stage startup with significant traction, on track to become cashflow positive this year—so there’s no frantic chasing of funding to stay afloat. Our team is small (currently 8 of us) by design, and we plan to grow to around 15 by the end of the year to ensure profitability. From there, we’ll scale linearly—about 3–5 new hires a month—depending on our sales results.

You’ll be working with an experienced development team that’s already built and scaled successful SAAS products. AIAIAI itself was born out of two sister companies, Lifely and Nucleoo, giving you access to a broader network of colleagues and experts in Amsterdam, Granada, and Madrid. We hope you look back in 20 years and say, “That’s where I did some of the most impactful and fulfilling work of my life.”

AI—yes, it’s a buzzword filled with smoke and mirrors. That’s not us (or at least, we’re trying not to be). Because no matter how slowly actual adoption might be happening, we’re all being affected by AI in one way or another—teachers feeling the pressure to adapt, office employees expected to deliver more in less time. There’s a huge segment of people, especially once you drive a bit outside big cities, who aren’t “prompting” or tapping into AI to boost productivity. Their jobs—and the relevance of their employers—is at risk. That’s what we address at

AIAIAI: helping everyday people use AI in a way that feels natural to them. We meet them where they are, instead of asking them to change. We’ve designed our product so that both employees and companies don’t end up saying “AI AI AI” three years from now because they were blindsided. It’s a product being used daily by users who’d typically fall into the late majority or even “laggards” on the adoption curve. And that’s the mission you’d help drive: making a fast-changing world a bit more manageable for people who just need it to work.

What can you expect from the role?

As our Full-stack web developer, you’ll help shape the core architecture of our platform—both front-end and back-end. You’ll be part of key decisions on how we build and scale, working alongside product managers, designers, and fellow engineers. You'll also implement AI features into our products, integrating with machine learning models, and crafting intelligent user experiences that leverage the latest AI technologies.

Responsibilities

• Full-Stack Feature Development

Develop, test, and maintain features across frontend (Svelte + TypeScript) and backend (Golang, Python).

• Architecture & Tooling

Contribute to choices around frameworks, libraries, and infrastructure, ensuring scalability and maintainability.

• API & Integration

Design and document RESTful APIs or gRPC services for robust service integration.

• AI Integration

Implement AI/ML capabilities in applications, work with relevant APIs (OpenAI, Anthropic, etc.), frameworks (Airflow, LangChain, LlamaIndex, etc), and develop user interfaces for AI-powered features.

• Code Quality & Deployment

Advocate for best practices, implement testing (frontend & backend), and optimize CI/CD pipelines.

• Collaboration & Troubleshooting

Work closely with cross-functional team.

Who are you?

Technical Experience

3+ years in full-stack development with solid JavaScript/TypeScript, front-end frameworks, and either Golang or Python (preferably both).

Cloud & Containerization

Familiarity with Docker, Kubernetes, and IaC tools like Terraform (we primarily use Azure, but any cloud background helps).

Database Proficiency

Comfortable with both SQL and NoSQL.

AI/ML Knowledge

Experience integrating LLMs and AI tools into data workflows and applications, including ETL/ELT pipelines using frameworks like Airflow, PyTorch, and LangChain.

Git & CI/CD

Experience setting up and maintaining pipelines (GitLab CI, Jenkins, etc.).

Analytical Mindset & Communication

Strong problem-solving skills and the ability to explain technical concepts to non-technical stakeholders.

Passion for AI Innovation

Have a genuine affinity for AI and keep tabs on high-level developments in the field.

Don’t let a partial skills match hold you back – if you have experience in most areas and can learn the rest on the job, we want to see your application. We believe in learning through doing and value candidates who can grow with us.

What do we offer?

Impact & Growth

Help shape how we onboard and retain clients at a crucial stage in AIAIAI’s growth. Your success will directly influence our speed of scaling—and your own career trajectory.

Location & Flexibility

Our office sits on the canals of Amsterdam, a hub of creativity and culture. As a rule of thumb, we believe it’s beneficial to be in the office between 2 and 3 days per week, but we’re not going to be a stickler about it.

A Stable Early-Stage Environment

We’re on track to become cashflow positive, so you’re joining a startup with real traction (and less existential risk).

Room to Innovate

We encourage you to bring your best ideas to the table within your contractual hours—minimal hustle-culture overdrive.

Collaboration & Community

While we’re a tight-knit group of 8, we’re also connected to the larger networks of Lifely and Nucleoo of 120+ employees, offering broader collaboration opportunities.

Competitive Compensation

We offer a salary and benefits package aligned with your experience, with a target range between €65,000 and €80,000 (all-in). Since we don’t have a direct benchmark for this role, we’ll collaborate with you to ensure the offer is fair and competitive based on your expectations.

No sponsorship

Unfortunately we are not able to provide sponsorship right now. Therefore you have to be an EU, EEA or a Swiss national to be able to apply for this job.

How to Apply

Send us your resume, portfolio links (GitHub, etc.), and a short note on why you’re a great fit. We’re excited to see how you can help us move the needle!
