Descrição da oferta de emprego

Joom Group is an international tech-centric group of e-commerce companies founded in 2016 in Latvia. We are here to transform the largest industry in the world, global trade, making it more transparent, efficient, and technology-driven.

Today, Joom Group brings together the following businesses: Joom, a platform for shopping from all over the world; JoomPro, the first end-to-end cross-border B2B marketplace, with successful operations in Brazil and plans to expand to other markets; JoomPulse, data platform that provides analytics and recommendations for marketplace sellers; and Onfy, a pharmaceutical marketplace in Germany. Joom Group’s offices are located in China, Brazil, Portugal, Latvia, and Germany, with headquarters in Lisbon, Portugal. We work as one international team, sharing knowledge and collaborating across countries, businesses, and products.

Our team is small and operates with high autonomy. We avoid the bloat of massive tech corporations. Instead, we empower individual engineers to solve problems that would typically require entire outsourced departments. At Joom, your work doesn't just improve metrics – it can fundamentally change the global trade.

About The Role

• Mission Critical: You will be working on most challenging problems and impactful products – whether it’s optimizing cross-border logistics through ML, architecting high-load B2B systems, developing service infrastructure with AI agents, or pioneering LLM-driven internal tools
• Direct Impact: Drive significant business impact by combining technical excellence with smart, innovative ideas that improve user experience and optimize business efficiency.

Who You Are

• You are an Exceptional Software Engineer: You have a track record of building complex, reliable systems and possess a deep understanding of the full stack, from infrastructure to ML-serving
• You are "AI Ready": You treat tools like Cursor, Claude Code, GitHub Copilot, etc. as extensions of your own capabilities to move faster and think bigger
• You are confident in making decisions grounded in data and measurable outcomes

Our Tech Culture

• High Engineering Density: Work in a compact, expert and strong team serving large business
• Advanced Tooling: We encourage use of the most modern tools available (OpenAI, Gemini, Anthropic, etc), allowing to build everything you can imagine
• Fast Loops: Our infrastructure is built for speed – experiment, deploy, and see the business effect in real-time

Values & Culture

• Move Fast: We operate in a hyper-dynamic and competitive environment, where challenges and opportunities pop-up every day and successes are immediately copied. That’s why we must move fast: make smart decisions, test hypothesis and quickly scale winning solutions
• Strive for Excellence: Move Fast doesn’t mean that speed is more important than quality. Only well-executed work can enable a startup to become a successful, long-lasting company
• Be Open and Honest: To become stronger, we openly discuss problems, are not afraid to acknowledge mistakes and look deeply into their core
• Together We Win: We only win when we play as one team. Regardless of business unit, country, or department, we work toward a shared goal and do what’s best for the team as a whole
• Innovate: We are here to create services that solve customer needs far better than existing alternatives

We offer

• Compensation package: base salary, performance-based bonuses and stock options
• Office-first: flexible hours with a possibility to work remotely 52 days per year
• Care & Wellbeing: health insurance (including dental care) for employees and their children, daily meal allowance, and 100% paid sick leave
• Relocation Support: full assistance for a smooth relocation for the employees and their family
• AI-first approach: licenses and access to a wide range of AI tools
• Team & Growth: collaboration with colleagues across Portugal, Brazil, Latvia and China, with opportunities for promotions, professional trainings, and English & Portuguese courses
• Community & Engagement: annual team building activities, knowledge-sharing workshops, and a strong sense of team work
