Climate Policy Radar
Greater London, England, United Kingdom • Hybrid
Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and build scalable backend services and APIs to transition the core product from a database to a data aggregator. Collaborate with product managers to implement GenAI, RAG, and multilingual capabilities to enhance evidence synthesis.
Requires significant experience in collaborative cross-functional teams and proficiency in Python and AWS cloud infrastructure. Candidates should be skilled in software engineering best practices and designing maintainable backend systems.
Climate Policy Radar is an independent non-profit building open, credible data infrastructure and AI-powered tools for climate, nature, and development action.
Our data and tools help governments, researchers, international organisations, civil society, and the private sector to understand and advance effective climate policies and deploy climate finance. Harnessing data science and AI – including pioneering applications of natural language processing in this field – we make previously unstructured, siloed data easier to find, understand, and act on.
We are a team of policy experts, engineers, data scientists, product thinkers, communicators, and operators. We care deeply about how we work – our values, culture, and ways of collaborating – as well as what we build. As part of that, we have embraced a flexible, hybrid approach to work, including a four-day workweek.
Climate Policy Radar's engineering org is split into a few functional teams: programmes (domain experts), platform (high-quality data sharing), application (user-facing tools), and data science (models and evaluation). Despite those splits, most of our work is cross-functional.
We are looking for a Senior Backend Engineer to join our Application team. In this role you will work with our Product Managers to create new features, improve our existing system, and design scalable solutions that will serve our growing user base.
Some of our priorities for 2026 that you could work on:
Helping us grow from a database to a data aggregator by improving our data import capabilities, including bringing in a new CMS
Laying the groundwork to make our core product multilingual in 2027 (French, Spanish & Portuguese), to open up information across linguistic boundaries
Improving the search engine in our core product to help people find what they are looking for
Incorporating GenAI and RAG into our core product to enable move us from search engine to evidence synthesis (e.g., summaries, Q&A, comparisons)
Sharing our data and services externally (e.g., via APIs) so that others can build upon our work
Tech Stack:
APIs & backend: Python, FastAPI, PostgreSQL
Data & infrastructure: Snowflake, Docker, AWS (ECS, S3, etc.), Pulumi, Prefect, GitHub Actions
Search: Vespa
Data Science: PyTorch, Huggingface, Pydantic AI, Pandas, Spacy, Weights & Biases
You have enthusiasm for:
Building and deploying backend services that are consumed by other teams, products, or external partners
Working with AWS services and cloud infrastructure
Software engineering best practices: requirements gathering, code review, testing, version control, documentation
Designing scalable, maintainable backend systems
Collaborating with Product and domain experts to solve meaningful problems
It would be a bonus if you had familiarity with:
Search Indexes
Generative AI
Devops and Observability

We are a mission driven organisation, and work best with people who have strong alignment with our values. We care about them deeply.
