Tech Lead (f/d/m)

A definitive shift is currently happening. Corporates across the globe are no longer just reporting on sustainability; they are actively investing in it as a core financial and strategic asset.

At CEEZER, we are architecting the infrastructure for enterprise-grade Climate Performance Asset management, transforming how the world's largest companies source and manage carbon credits, Energy Attribution Certificates (EAC), and Sustainable Aviation Fuel certificates (SAFc).

Our platform gives the world’s most ambitious enterprises the data-driven precision, real-time monitoring, and framework-compliant reporting required to confidently deploy capital toward high-impact Climate Performance Asset portfolios and true, measurable climate action.

Tasks

Your mission

We are looking for a Tech Lead to join our engineering team. This role requires an ambitious technical leader who can architect scalable systems, navigate complex carbon data architectures, and drive engineering excellence. Moving beyond traditional software delivery, you will translate product vision into reliable technology, lead critical architectural decisions, and leave a lasting mark on our platform from day one.

• Architect and scale a seamless B2B procurement platform, delivering an intuitive, enterprise-grade user interface designed for daily engagement and complex workflows.
• Drive end-to-end technical strategy, design, and architecture, translating ambitious product requirements into performant, scalable features and microservices.
• Lead by example with hands-on technical execution, authoring high-quality, maintainable code across our TypeScript, Node.js, and Next.js stack.
• Cultivate engineering excellence across the team, providing high-impact mentorship, technical guidance, and rigorous code reviews to continuously elevate development standards.
• Safeguard platform integrity, establishing robust security, reliability, and performance standards across our applications and core cloud infrastructure.
• Partner closely with product, design, and cross-functional teams, evaluating trade-offs and technical permutations to engineer optimal, user-centric solutions.

Requirements

What you need to succeed

• 5+ years of professional software engineering experience, with a proven track record of technical leadership (2+ years) guiding teams through complex, full-lifecycle product deliveries.
• Deep technical proficiency in TypeScript and the Node.js ecosystem, alongside extensive hands-on experience building modern, data-dense interfaces with React or Next.js.
• Strong architectural expertise in RESTful API design, backend systems architecture, and relational data modelling (PostgreSQL experience preferred).
• Demonstrated commitment to engineering rigour, with a deep understanding of software design patterns, enterprise web security standards, and modern development workflows (Git, feature branching).
• Familiarity with cloud-native infrastructure and continuous deployment, including hands-on experience building and maintaining services on platforms like AWS.
• Exceptional collaborative and communication skills, with the ability to articulate complex technical decisions, bridge alignment across product teams, and mentor engineers.
• Basic familiarity with Python is a plus, or a strong technical curiosity to expand into auxiliary parts of our data processing stack.

Benefits

What's in it for you at CEEZER?

• A mission that matters: Work alongside international teams combining finance, tech, and climate science professionals to direct capital toward the world's most critical climate assets.
• Accelerated growth: We are scaling fast, and your career will too. Take opportunities to lead cross-functional initiatives and expand your strategic influence.
• True ownership: We are building in a brand-new market, meaning many of our best practices don’t exist yet. If you see a better workflow, tool, or strategy, you have the autonomy and backing to build it.
• An empowering environment: We bring together diverse global perspectives, knowing that solving complex climate challenges requires a wide mix of backgrounds and expertise.
• Real enterprise impact: Transform how global corporates approach sustainability. CEEZER hosts 50Mt+ of vetted carbon credits across all pathways, all backed by sophisticated data and institutional-grade risk management.
• A net-zero career: We practice what we preach. From your first day, we fully offset your personal and professional carbon footprint because sustainability is how we operate.
