Staff Software (Full Stack) Engineer

About Us

Climate X is a purpose-driven climate adaptation data company set to revolutionise how the world manages assets, property, and infrastructure.

We apply cutting-edge, peer-reviewed science to help prevent the worst impacts of climate change. Our innovative approach combines climate projections, remote sensing observations, and sophisticated modelling to project the frequency and severity of physical climate risks such as floods, subsidence, and storms.

Our flagship SaaS platform, Spectra, combined with our Adapt solution, provides a comprehensive climate risk and adaptation planning toolkit. Spectra enables financial institutions and real estate firms to explore future climate pathways and:

• Identify potential property and company asset damage from severe weather events
• Assess the impact of climate risks on asset valuations
• Build climate resilience and make data-driven investment and lending decisions
• Generate detailed physical risk ratings and climate-adjusted Value at Risk (cVaR) forecasts through 2100
• Analyse risks at unprecedented granularity (down to 10x10m in urban areas)

Our Adapt platform builds on Spectra's foundation to:

• Transform risk insights into actionable adaptation strategies
• Provide structured frameworks for climate adaptation planning
• Enable vulnerability assessments and thresholds analysis
• Support organizations in implementing and monitoring adaptation measures

We advocate diversity with our founders, team, and investors from various backgrounds. We're not building just a team but a place of innovation where problem-solving and fun coexist to address the most significant challenge our society faces today.

The Impact You'll Own

As Staff Engineer, you will provide technical leadership across our product suite, including Spectra, Adapt, and our upcoming Spectra for Corporates platform.

Key Responsibilities:

• Architect and implement scalable full-stack solutions handling complex, semi-structured data streams

• Design and evolve our enterprise-level server-side frameworks for efficient data processing and analysis

• Lead technical design reviews and establish best practices across our engineering teams

• Provide technical mentorship and guidance to team members while fostering a culture of engineering excellence

• Drive technical strategy for integration between our Spectra, Adapt, and Carta platforms

• Collaborate with data scientists and researchers to optimize our climate risk models for production environments

• Champion scalable architecture decisions that support our growing user base and expanding feature set
