💫 Our Engineering teams

As a Software Engineer, you’ll have the opportunity to apply your skills across a wide range of cutting-edge technical challenges and impactful projects. Depending on your expertise and interests, you could contribute to one of the following key areas:

1. Tech: Collaborate with the Product team to innovate on Joko’s user-facing products and shape the future of the online shopping experience, taking full ownership from conception to deployment. You will tackle complex engineering challenges such as developing AI-powered shopping assistants or crafting scalable algorithms that are capable of extracting, structuring, and leveraging massive quantities of data from all e-commerce sites worldwide.
2. Operations: Support all teams at Joko by designing and implementing software solutions that enhance efficiency at scale. You will work on projects like building the customer support stack to solve our users’ problems, improving fraud detection mechanisms, or creating AI assistants to optimize team operations.

🎯 What you will do

At Joko, we believe in ownership and versatility. You will take complete ownership of your projects, steering them from the initial blueprint to their deployment in production, ensuring excellence and innovation at every turn. We aim to assemble versatile teams of engineers, not confined to narrow specialties (e.g., mobile development, ML engineering, infrastructure, etc.). We seek individuals with broad technical skills, capable of applying their knowledge to tackle complex, multi-domain engineering challenges. As a Software Engineer, your responsibilities will include:

• Software design & development: Translate product visions or operational needs into robust software architectures, implementing them across our stack to ensure an exceptional user experience.
• Technical exploration & problem-solving: Dive into challenging technical problems, often involving new and undefined areas, using innovative approaches to develop practical solutions.
• Deployment & impact monitoring: Take projects from development to deployment, collaborating with Product and Data teams to monitor their impact.
• Technical leadership: Set technical direction, own architecture decisions on complex systems, mentor engineers across the team, and drive the hardest technical discussions to a resolution.
• Strategic collaboration: Work closely with the Product and Operations teams to align technical projects with company goals.
• Process & tool enhancement: Continuously evaluate and improve team processes and tools to ensure maximum efficiency and effectiveness.

👀 Who we're looking for

We’re looking for talented engineers who combine technical excellence with curiosity, ownership, and a product-driven mindset. You might fit perfectly if you recognise yourself in the following:

• Experience: You have 5+ years of experience as a software engineer, including time spent owning complex, ambitious projects end-to-end. You've operated at a senior or staff level, taking responsibility for technical direction and not just execution.
• Track record: You’ve demonstrated high potential through one or more of the following:
  • Strong experience or growth in a top-tier company or project;
  • A strong entrepreneurial or open-source background;
  • Speaking at conferences, organising meetups, or contributing to tech communities.
• Builder’s mindset: You think in terms of impact and see technology as a means to create real value for users.
• Full-stack spirit: You’re not limited by a specific layer or language. You care about solving problems end-to-end.
• Fast learner: You’re quick to pick up new technologies, frameworks, or practices, and you’re comfortable in fast-changing environments.
• Problem solver: You have strong analytical skills and enjoy tackling complex challenges with a creative yet pragmatic approach.
• Communication: You can explain complex ideas simply, structure your thoughts clearly, and listen actively.
• Team player: You’re humble, open to feedback, and eager to help others grow as much as you grow yourself.
• Drive & ownership: You take initiative, hold yourself accountable, and aim for excellence in everything you do.
• Languages: You're fluent in English, both written and spoken. French is not required.
