Start UpHorario FlexibleProduct

Sparta is revolutionising the commodity trading industry with a B2B SAAS that does away with the Excel spreadsheets that traders have been working with for decades.

Just one year after launching the MVP, they have reached over 50 customers, received fantastic feedback and earned €2M in recurring revenue. They are therefore ready to grow the company. Are you a data and development lover and would you like to learn more about them? Read on :)

¿Qué harás?

At the moment, the backend and data team are managing the infrastructure, and they want to start bringing in specialists to help address the new challenges facing the company: improving the current product and growing vertically towards other commodities.

The type of person they're looking for is someone who brings their experience to the table, who's hungry, and who helps them to continue to grow. A team player, who likes to share and learn in equal parts, and whose objective is to continue to grow and help the team to find solutions for each challenge. And of course, you'll always be given the freedom to do what you do best.

But let's take a look back at how they got to this point... ^__ ^

Felipe (CEO) and Miles (COO) decided to leave the world of oil trading in 2019, after working in this field for more than 35 years. Knowing that the wave of digitalisation, and new technologies had not yet reached the commodities trading market. Together with Luis (CTO), they decided to start Sparta, in order to automate, optimize, and increase the productivity of commodities traders.

To be a good trader, you have to know how to make decisions. To do so, you need to have all the relevant information at your fingertips so that you can take advantage of market opportunities and be faster than the competition. This is where Sparta has revolutionized the industry, as its platform not only aggregates the most relevant information, but also processes it and allows traders to communicate with their teams quickly and efficiently in the cloud. In addition, they allow trading firms to create their own databases featuring the most relevant historical information in order to learn from past experiences. This all takes place in the cloud and is therefore accessible from anywhere, meaning remote work is possible in a sector in which it is not at all common.

In late 2020, they launched their MVP on the web and on iOS, while in 2021, they focused on growing the team and developing the tool. They are now concentrating on continuing to grow, expanding into other markets and using all the data that, currently, they alone possess.

Tu evolución

Tu primer día

En 1 mes

The first month will be about settling into the team, getting to know people and getting used to work 100% remotely (if you don't have previous experience with this). They want you to have a say and will value the feedback you can give them about the way they do things, right from day one. Every member of the team is important for Sparta's growth and, of course, they want you to help them evolve all aspects of the organization. 

During the first month, you'll become familiar with the dynamics of the team and the market in which they operate. You'll also be introduced to the product dynamics, and the backend and data team will introduce you to the infrastructure already deployed.

Tus responsabilidades

  • Helping implement and maintain the AWS infrastructure.

  • Design future changes for the architecture.

  • Suggest improvements based on metrics and your experience.

  • Monitor the services already deployed and create alarms for situations of underperformance.

  • Manage overall system security and administer access accounts to the infrastructure.

  • Introduce new technology to improve the speed, efficiency, and reliability of our platform and you will tune existing tools to improve our developer experience.

  • Drive the automation of the development and deployment processes via a range of new technologies and techniques

  • Help manage infrastructure costs and plan for future expenditure.

  • Maintain and optimize the different integration and continuous deployment environments.

  • Improve internal tools in order to increase development productivity.

¿Cómo lo harás?

The technical team consists of two multidisciplinary squads focused on different parts of the product, and one team focused on data. You'll join one of these squads and you’ll be the anchor point of the infrastructure.

The product teams are managed through SCRUM. You'll join a product team in order to provide support in the area of infrastructure and help address its needs. However, you'll also join a multidisciplinary team alongside the CTO in order to contribute your expertise to the development of the roadmap, and to propose solutions and improvements to the current infrastructure.

¿Cuándo trabajarás?

At Sparta, staff really DO enjoy flexible working hours. The only thing they ask is that all members of the team are available during a particular time slot so that you can coordinate (you know, the daily, the Retro, meetings to discuss decisions, and so on.

¿Dónde trabajarás?



Sparta began as a 100% REMOTE company. Felipe is based in Geneva, Miles in London and Luis in Basel and from that structure they have been growing.

The team is distributed throughout Spain, the UK and Switzerland and they strongly believe in the advantages of working remotely and in work-life balance:)

However, your expenses will be covered if you'd prefer to work in a co-working space.

What's more, they plan to meet up in person from time to time in a chosen location, so that it's not all virtual. Whenever they get together it is always a great success!

¿Con quién trabajarás?

The team is well-balanced, experienced, and well-oiled ❤️‍🔥. New staff will be added, but to date, the team consists of 20 people making the product a reality :).

  • Miranda Chong (VP of Data) - She has spent the past 13+ years working with all things data. She is passionate about leveraging data to create insights, with hands-on experience in building and productionising data pipelines and machine learning models.

Her role in Sparta is to build out the data capabilities and long-term roadmap to support Sparta's growth strategy. 
  • Paul Laight (CTO) - He has 20 years of experience building highly complex products, platforms, companies and teams within the FinTech space.

What the FAQ?

For administrative reasons, they can manage recruitments in Spain, the UK and Switzerland.

NO. The team is spread over locations from Cordoba to London, from Valencia to Basel.

They organise occasional face-to-face events lasting a couple of days and hope that you'll want to attend. Of course, they'll cover the cost of these trips :)

No, they're a very agile team and this is reflected in the process itself.

  1. There'll be an initial meeting with the CTO/VP of Engineering so you can get to know each other.
  2. The second phase involves meeting with the technical team to discuss technical issues and replicate the working dynamics.
  3. A final meeting with the CEO and COO :)
