Role Description

Chemonics International is conducting a recruit for a Sr. Software Developer for Alchemi Venture Studio, our investment subsidiary that mobilizes private‑sector capital to back innovative, inclusive, and sustainable development solutions. Alchemi is seeking a proactive, self-managed Senior Software Developer to own end-to-end design, development, testing, and deployment of modern web applications and AI-driven systems. The role is hands-on, individual contributor focused, with significant autonomy in technical decision-making and product experience design.

We are looking for individuals who have a passion for making a difference in the lives of people around the world.

• This role focuses on hands-on software design and development, contributing to systems architecture, collaborating with technical leaders, and implementing secure, innovative solutions across domains such as financial technology, artificial intelligence (AI), supply chain, and other areas as directed.
• Design, build, and maintain full-stack applications using React, Next.js, TypeScript, and Python, with a strong emphasis on clean architecture and high-quality code.
• Own end-to-end delivery: requirements clarification, solution design, implementation, automated testing, CI/CD, and production deployment and monitoring.
• Architect and implement backend services on AWS (e.g., API gateways, serverless functions, containers, storage, and data services) with a focus on scalability, reliability, and cost efficiency.
• Develop and maintain Supabase-based backends, including schema design, auth, and Edge Functions for custom logic and integrations.
• Integrate and operate deployments on Vercel, optimizing build pipelines, performance, and observability across environments.
• Use GitHub for version control, code review, and workflow automation; help enforce best practices in branching, reviews, and CI.
• Design and implement AI-powered features using LangChain and LangGraph, including multi-agent systems that orchestrate tools, external APIs, and knowledge bases.
• Leverage AWS AI services (including Bedrock) to build intelligent application features such as search, summarization, personalization, and assistants.
• Model and build knowledge graphs using Neo4j and Apache AGE, integrating them into applications for advanced querying, reasoning, and recommendation.
• Collaborate closely with product and design to deliver excellent UI/UX, including interaction design, information architecture, and responsive layouts.
• Write comprehensive automated tests (unit, integration, and end-to-end) and establish quality gates as part of the development workflow.
• Drive technical discovery and prototyping of new tools, frameworks, and patterns, sharing findings with the team and influencing technology choices.
• Diagnose and resolve complex production issues across the stack, including performance bottlenecks, reliability problems, and data inconsistencies.

Qualifications

• 6 or more years of professional software development experience, including substantial end-to-end ownership of complex applications.
• Strong proficiency with React, Next.js, and TypeScript for building modern, responsive web interfaces.
• Solid experience with Python for backend services, scripting, and AI/ML-related integration work.
• Hands-on experience with AWS services for application hosting, data storage, and integration (e.g., Lambda, API Gateway, ECS/Fargate or similar, S3, RDS/managed Postgres).
• Practical experience building and operating backends on Supabase, including Postgres, Auth, and Edge Functions.
• Experience deploying and operating applications on Vercel, including environment configuration and performance optimization.
• Strong GitHub skills: branching strategies, pull requests, code review, and CI workflows.
• Demonstrated experience building AI-enabled applications using frameworks such as LangChain and LangGraph, and familiarity with multi-agent system patterns.
• Experience with AWS AI offerings (e.g., Bedrock or similar managed model-hosting services) and integrating them into product features.
• Working knowledge of graph databases and knowledge-graph design using Neo4j and/or Apache AGE.
• Proven ability to design intuitive, polished user interfaces and user flows, with a portfolio or examples of past UI/UX work.
• Excellent communication skills, with the ability to work independently, manage priorities, and collaborate asynchronously.
• Ability to solve technical, managerial, or operational problems and evaluate options based on relevant information, resources, well-rounded experience and knowledge.
• Entrepreneurial mindset, familiarity or experience working with innovation and scaling approaches preferred.
• Demonstrated ability to synthesize and convey complex ideas effectively.
• Ability to work in a team and independently on projects and tasks.
• Demonstrated leadership, versatility and integrity.
