At osapiens, we are committed to empowering businesses economically while promoting human rights and establishing ecologically sustainable and responsible corporate governance as a global standard.

We support global enterprises in over 60 countries in integrating sustainability and positioning themselves for the future. To achieve this, we develop comprehensive SaaS solutions that create transparency and sustainable growth across the entire value chain, meet ESG requirements, and automate manual processes.

Your Mission

As a Technical Team Lead you’ll play a key role in shaping the future of Business Partner Transparency (BPT) within our osapiens HUB. This enterprise-grade platform helps companies comply with critical ESG regulations like:

• The German Supply Chain Due Diligence Act (LkSG) – ensuring suppliers uphold human rights and environmental standards.
• The Whistleblower Directive – providing secure, anonymous reporting channels.
• The Corporate Sustainability Due Diligence Directive (CSDDD) – upcoming EU-wide sustainability compliance.

In this role, you will combine technical expertise with leadership, guiding a team of 5-7 engineers to build scalable, high-impact solutions. You will shape the team’s technical direction, champion best practices, and work closely with product managers to translate business needs into effective solutions.

Our osapiens HUB is a modern, enterprise-grade development platform that enables businesses to build powerful applications without worrying about infrastructure, scaling, or failover. You’ll help develop and refine this cutting-edge, serverless ecosystem while delivering meaningful solutions for international clients.

This role is based in Mannheim, a vibrant tech hub at the heart of Germany, where you'll collaborate with a talented, forward-thinking team. We embrace a hybrid work model, with three days a week in the office, ensuring the perfect balance between in-person collaboration and remote flexibility.

• Fostering team growth by mentoring engineers, providing guidance, and creating opportunities for professional development.
• Staying ahead of industry trends by researching and introducing new technologies that improve performance, scalability, and maintainability.

Your Experience

• Demonstrating proven leadership experience by having previously led teams as a Team Lead, Tech Lead, or Senior Engineer, with a strong focus on mentoring and guiding team members.
• Bringing expertise in TypeScript, React, and Node.js by developing scalable, high-performance applications with modern full-stack technologies.
• Applying a deep understanding of agile development by thriving in fast-paced, iterative environments and continuously improving team workflows.
• Exercising excellent problem-solving skills by breaking down complex business requirements into simple, effective technical solutions.
• Communicating effectively with stakeholders by collaborating seamlessly with both technical and non-technical teams to drive alignment and clarity.
• Embracing a servant leadership mindset by empowering and enabling your team to excel, fostering a culture of growth and continuous improvement.
