Full Time

LatAm Remote (U.S. Time Zones required)

About Us

Ezra is a venture-backed startup building at the intersection of sustainable finance and artificial intelligence. Our mission is to accelerate capital deployment to climate solutions and other world-positive investments. Finance is a huge lever we can pull to get more climate technology deployed in the world, and we believe our software platform can meaningfully accelerate progress. AI applications and agents are foundational to our suite of solutions. We move fast, stay close to our customers, experiment constantly, and believe in launching, learning, and iterating quickly. We're a small and experienced team.

About the Role

We are seeking a seasoned, full-stack Senior Engineer to significantly contribute to the development and scaling of our core platform. This role is for a proven generalist who is deeply product focused and takes complete ownership of features from concept to production. You will be expected to make significant contributions across our entire stack, Python (FastAPI), Typescript (Next.js/React), and AWS/Terraform, focusing on delivering high quality, impactful features for our customers. This is a high autonomy role where you will be an independent driver of technical solutions, leveraging your expertise to solve complex problems and rapidly deploy new value in a fast paced, startup environment.

Core Responsibilities

•Own the technical delivery of full-stack product features end to end, collaborating directly with Product Management and Design to define requirements, break down epics, and ensure engineering quality and speed.
•Design and develop scalable components and APIs across our backend (Python/FastAPI) and frontend (Next.js/React).
•Contribute to system architecture decisions and implementations for high traffic production environments.
•Drive necessary changes, conduct thorough code reviews, and debug issues across the entire application stack.
•Work closely with AI/ML engineers to integrate, serve, and iterate on model powered features and data pipelines.
•Contribute to the management and evolution of our infrastructure, primarily utilizing AWS and Terraform.
•Act as a technical leader, mentoring peers, driving best practices, and ensuring full-stack consistency, performance, and reliability.

Required Skills & Experience

•Minimum of 6 years of dedicated professional full-stack development experience. (Preference for 10+ years.)
•Minimum of 3 years of hands-on experience with our core stack: Python, FastAPI, Typescript, Next.js, React, AWS, and Terraform.
•Extensive experience designing, building, and operating production grade, customer facing SaaS and web applications end to end.
•Significant experience in a small startup environment (e.g., one of the first few engineers, seed/Series A), where success required high self motivation, ownership, and concurrent contribution across product, infrastructure, and operations.
•Expert level backend engineering with Python, FastAPI, and robust database experience (Postgres, SQLAlchemy).
•High proficiency in modern frontend development with Next.js/React.
•Strong infrastructure experience: AWS services, Terraform, observability tooling, monitoring, scaling, and resiliency.
•Demonstrated ability to drive feature development independently, balancing long term architectural longevity with the rapid delivery of customer value.
•Excellent communication skills and the ability to explain complex technical concepts clearly.

Preferred Qualifications

•Familiarity with financial data, documents, and relevant security best practices.
•Prior experience with AI/ML services and serving models in production.
•Experience with agentic AI platforms and tools or information retrieval systems.
•Experience building or working with Retrieval Augmented Generation (RAG) systems.
•Practical experience utilizing coding Large Language Models (LLMs) in development (e.g., Claude Code, Cursor, GitHub Copilot) to enhance speed and quality.

You'll Excel in This Role If You

•View your role as a Product Engineer/Owner who is accountable for a feature's success, focusing on customer impact and business outcomes.
•Are comfortable operating with high ambiguity, defining the project, architecture, and deployment strategy with minimal external direction.
•Enjoy the fast pace and high autonomy of an early stage company, where you get to build both scrappy proofs of concept and scalable, robust products.
•Are passionate about climate finance and sustainability and want to have a big impact on the progress of our platform and mission.
•Are comfortable making technical decisions autonomously, but proactively seek feedback and collaborate effectively with the team.

What We Offer

•High autonomy and complete ownership of your work.
•Fast paced, experimental, and challenging environment.
•Direct access to customers and immediate feedback loop.
•Opportunity to work on meaningful problems in climate change and technology.
•Competitive salary and equity package.
•Remote friendly work environment.
•Comprehensive health benefits and flexible vacation policy.
