Product Engineer (Backend/AI) @Briink

About This Opportunity

We are representing a well-funded climate technology organization based in Berlin that builds AI-powered solutions for the global sustainability sector. Our client works with major multinational corporations and leading climate institutions to automate how environmental data is collected, analyzed, and acted upon at enterprise scale.

This is a rare opportunity to join a small, high-impact engineering team where your work directly influences sustainability workflows used by thousands of organizations worldwide. You'll own product features end-to-end, combining strong backend engineering with applied AI/LLM capabilities to ship meaningful solutions for sustainability professionals.

Responsibilities

• Own product features from discovery through delivery, working directly with users to understand problems and iterating based on feedback and product data
• Design and build scalable backend systems including APIs, data models, workflows, and infrastructure for complex enterprise products
• Build and ship applied AI/LLM features such as RAG systems, tool-using agents, structured-output pipelines, and evaluation workflows
• Create reusable, extensible platform building blocks that support multiple user journeys rather than solving problems in isolation
• Improve system robustness by strengthening reliability, testing, observability, performance, and maintainability as the platform scales
• Prototype and test new AI capabilities, turning promising ideas into practical product improvements
• Collaborate closely with other engineers through pair programming, technical design discussions, and shared problem-solving
• Bring thoughtful opinions and constructive challenge to help the team make better product and technical decisions

What We're Looking For

Required qualifications:

• Strong professional backend engineering experience with a track record of designing and shipping reliable production systems
• Experience in a small, high-ownership product team, ideally within a startup or scale-up engineering organization of roughly 5–20 engineers
• Evidence of shipping meaningful products end-to-end rather than owning only narrow components within larger organizations
• Strong experience in Python, or another modern backend language (Java, Ruby, TypeScript) with willingness to become productive in Python quickly
• Strong API, database, and systems design skills with ability to model complex workflows and build maintainable foundations for enterprise products
• Applied AI/LLM experience or strong interest in LLM-powered features, ideally involving RAG, retrieval, tool use, agents, structured outputs, or evaluation systems
• Solid software-quality mindset including testing, code review, CI/CD, observability, and pragmatic approaches to reliability and security
• Cloud and container experience with understanding of how to deploy, operate, and scale production workloads
• Fluent English (C1+), both written and spoken

Nice to have:

• Experience building workflow, reporting, questionnaire, or other complex B2B SaaS products
• Familiarity with FastAPI, PostgreSQL, background queues, or LLM frameworks
• Deeper experience with RAG, retrieval, agents, LLM evaluation, and production AI systems
• Experience improving latency, cost, and reliability for AI workloads
• Knowledge of ESG, sustainability, climate tech, or corporate reporting
• German language skills

Personal attributes:

• Kind and collaborative with clear communication skills
• Mission-driven with genuine interest in using technology to accelerate sustainability and climate action
• Sharp, curious, and able to get to the root of difficult product and technical problems
• Product-minded builder who thinks beyond individual tasks and focuses on creating user value
• Highly self-directed and able to thrive in fast-moving environments with autonomy and ambiguity
• Pragmatic and action-oriented, able to move from ideas to experiments to production efficiently
• Opinionated but open-minded, welcoming constructive challenge and pushback
• Commercially aware with ability to balance technical quality with user needs, business value, and speed

Location: Berlin-based or London-based candidates strongly preferred for hybrid work arrangement
