Lead AI Engineer

ABOUT US

In 10 years, all companies will operate a non-financial system. As we see it, it’s either Dcycle or bust.

Business decisions are primarily based on financial data. This is because this information has gained reliability over the decades thanks to two key factors: standardization and digitization. Thanks to this, companies can understand their financial performance, access financing, and operate better.

However, non-financial information, such as that related to governance, people, operations, or supply chain, remains outside that decision-making process. Why? Because it's not reliable. It's not digitized or standardized like financial information. It's usually scattered across Excel files, disconnected from the rest as it's managed in silos, and by profiles unable to solve the reliability problem because they're not IT experts.

What many companies don't see is that financial information is largely a direct consequence of what happens in non-financial areas. If we don't understand those areas well, we're making decisions without considering a good part of the context. And that, inevitably, leads us to make worse decisions.

At Dcycle, we give companies total control over their non-financial information, so they can use it easily to be more competitive.

The world is changing. The rules of the game are too. But the infrastructure with which companies make decisions remains trapped in spreadsheets, information silos, and eternal consultancies.

Dcycle exists to correct that partial blindness.

Our mission: Dcycle exists to give companies total control over their information—financial and non-financial—so they can operate with complete vision, not with a blindfold over one eye.

Without control, there are no good decisions.

And we are building an amazing team to make it happen.

YOUR JOB

We are looking for a Lead AI Engineer to drive Dcycle’s competitive advantage in this field. You will have two main responsibilities:

1. Integrate top-tier AI capabilities into Dcycle’s product.
2. Collaborate with the rest of the company to deploy AI as a work companion to make the company more efficient and enhance our human capabilities.

You will constantly research and apply the most innovative technologies to address emerging challenges.

In 2025, Dcycle faces two major challenges: tripling the company’s revenue and scaling internationally.

In one month…

You will have completed our best-in-class onboarding, designed to ensure your success from your first day. It will include working on practical sustainability cases to better understand our customers’ daily challenges, meeting with key people, and understanding our objectives and the way we do things at Dcycle.

You will start discovering our Digital Product philosophy, and we will introduce you to all the teams at Dcycle.

You will start making an impact through your daily job, we want you to be confident and start contributing from day one.

You will always be surrounded by colleagues who will support you every step of the way.

In three months...

By now, you will feel like a full-fledged member of the team. You will have already made an impact at Dcycle through your first milestones:

• Designing and deploying AI models that process messy real-world sustainability data: natural language, structured formats, supplier reports, certificates, etc.
• Prototyping fast with product and design teams: you’ll help validate ideas early with smart implementations.
• Actively contribute to product discovery, working closely with clients, business and product teams to ensure technical feasibility early.
• Building production-grade pipelines: deployable, monitorable, and maintainable ML/LLM systems in a real product used by real people.
• Staying lean but rigorous: We’re not after “AI for AI’s sake.” You’ll help us distinguish what’s worth doing now vs. what’s noise.
• Be a technical mentor to the team — leading by example, sharing knowledge, and supporting engineers across all levels.

You will realize that you are in an extremely demanding, dynamic, and creative environment, surrounded by highly talented people who genuinely care about your growth. You will receive continuous coaching through weekly 1:1s.

Most importantly, you will feel part of something important: your job will have a meaning; your colleagues will become close friends and you will notice that you have no idea about a lot of things you thought you knew. Learning will become an everyday task.

In six months...

You will feel that Dcycle has changed your professional life forever.

Bold statements, we know—but this is literally what 100% of the people who have been in your position have felt.

You will feel like Vanesa:

Oh! And you’ll have attended your first team building. Twice a year we go crazy and have fun somewhere in the nature. Last team building we climbed El Teide at night and watched the sunrise from the top 😉.

HOW WILL YOU DO IT?

At Dcycle, we take inspiration from models like La Masía at FC Barcelona, one of the most prestigious and recognized football academies in the world. La Masía is much more than just a training facility; it is a true talent factory that has shaped some of the greatest legends in football.

Its success lies in a holistic approach that combines a clear playing philosophy, an innovative methodology, and a long-term commitment to the technical, tactical, and personal development of its players. Beyond football, La Masía also prioritizes the education and well-being of its talents, shaping well-rounded individuals prepared for challenges both on and off the field.

At Dcycle, we embrace a long-term vision and a comprehensive development philosophy. We are not just looking for immediate results, but for people with the potential and determination to make a difference. We prioritize professionals who share our mission: giving companies control over sustainability.

We don’t just evaluate technical skills or past achievements; we focus on individuals with curiosity, critical thinking, and a commitment to continuous learning. We want people who don’t just complete their tasks but challenge ideas, bring new perspectives, and drive change. With this approach, we create an environment where personal and professional growth go hand in hand, and every challenge becomes an opportunity to innovate and make an impact.

You’ll Thrive Here If You…

• Like autonomy and get a kick out of proposing ideas, owning them, and shipping them.
• Think end-to-end: from first experiment to user impact.
• Are not afraid of ambiguity and love turning mess into clarity.
• Enjoy collaborating with product thinkers and designers, not just other engineers.
• Know how to balance experimentation with productization.

The people who belong in Dcycle are:

1. Number 1 → Willing to pay the price to become better, passionate about what we do, energetic, and hungry for challenges.

2. We fix what’s broken → with autonomy and responsibility.

3. We take humor seriously → spending time together is a pleasure.

4. Intelligent → we learn quickly, are versatile, and technically brilliant at something.

The people who belong in Dcycle act:

1. With confidence → whether acting autonomously or seeking opinions and getting involved; we value feedback as the only way to grow.

2. Guided by metrics → we rely on key metrics to evaluate our efforts.

3. Close to the customer → we maintain constant, iterative conversations with our customers and prospects to learn from our experiments (both about the problems and the solutions we create).

4. By taking risks → we understand that failure is the price of learning.

This creates our competitive advantage, which makes us win:

• We are faster.

• We are more demanding.

• We are bolder.

When you will do it

Full-time, 40 hours per week, Monday to Friday (flexible start between 8:00 - 9:30 AM and end between 5:00 - 6:30 PM), with an early finish at 3:00 PM on Fridays.

Where will you do it

Innovation requires seamless collaboration. At Dcycle, we believe impact comes from being present. We love having the whole team together—creating, helping each other, and having a great time. But after the first month, we offer up to two remote work days per week if you need them to recharge and get shit done.

Who you will do it with

Nothing demotivates top talent more than working with mediocrity. That’s why we only hire the best. We aim for every new hire to be better than the current average, which is very challenging given the extremely high level at Dcycle. Here are some of them:

• Diego Acuña: The first developer at Dcycle. A fantastic individual who has become the best Product Engineer in Spain. In just three years, Diego has risen to Product Maker, leading a multidisciplinary team that collaborates across the entire company.
• Boris Landivar: Environmental engineer from the Polytechnic University of Madrid, ranked first in his class. Boris (we call him the Peruvian Tiger) has gone from intern to leading a product team in just three years.
• Cecilia Bayas: PhD Summa Cum Laude from the Autonomous University of Madrid. No further explanation needed.
• Jaime de la Torre: a startup veteran, Jaime was the second hire for Amazon’s launch in Spain, served as Fever’s first COO ($2.1B valuation), managed Airbnb’s market in Spain, launched Badi Homes, and was COO at Reby (€100M exit).

FAQ

• How does the hiring process look like?
  • We are truly proud to have a particularly tough selection process. We believe that what motivates a great professional the most is working side by side with other great professionals, so we make an effort to raise the bar with every new teammate we hire.
  • The process consists of a brief qualification call (15 min), an in-person or video interview with Operations (45 min), an in-person interview with the Hiring Manager (60 min), an in-person values interview (45 min), and an in-person interview with the founders (60 min).
  • Depending on the position, we may ask you to prepare a brief business case or tech skills assessment. We know the last thing you want after you finish your regular job is to start with yet another business case, so we commit to making it as light and brief as possible to your day to day, and to invest as much time in reviewing it as you invested in preparing it.
  • We want to respect your time as much as possible, so we commit to providing feedback within 12 hours from your interview, and providing a slot for your next interview within the next two days. In the best-case scenario, no more than 10 days will pass from your first call to signing the contract.
• Can I apply if I live out of Spain?
  • As long as you have a valid work permit for Spain and are willing to move to Madrid, we are happy to consider your application. We regret that we are unable to process work permits at this time.
