• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
• A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.

Preferred / Bonus:

• Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
• Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
• Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.

What we offer

• A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
• A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
• Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).
• Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.

About this role

Technology plays a central role in how GiveDirectly delivers cash—whether that’s identifying recipients in hard-to-reach places, sending payments quickly after disasters, or powering the platforms our donors use to give.

We’re hiring a Senior Software Engineer to help build the systems behind this work. Our engineering team still operates like a startup within GiveDirectly—lean, fast-moving, and high-autonomy. You’ll lean into product thinking, help shape the roadmap, and collaborate closely across disciplines to solve real-world problems. The specific team you’ll join is still being finalized—it could be:

• Our Programs Engineering team (getting cash in the hands of people experiencing extreme poverty),
• Our Fundraising Engineering team (raising more money for recipients), or
• Our International Rapid Response team (getting cash to disaster-affected communities within 5 days of a crisis—anywhere in the world)

No matter the team, you’ll play a central role in scaling our impact: getting more money, to more people, more efficiently.

This is a hands-on role with real ownership. You’ll help shape architecture, ship production-ready code, and work side-by-side with teammates across product, data, and operations. We’re looking for someone excited to wear multiple hats, move quickly, and define what great engineering looks like in a mission-driven org

Level: Senior Software Engineer

Travel Requirement: Must be able to travel ~1-2 times per year to one of our countries of operation for team retreats or field visits.

What you’ll do:

• Design and build scalable, reliable systems that power our core operations—whether that’s donor platforms, systems that deliver payments directly to recipients, or crisis response tools reaching hundreds of thousands of people globally.
• Own end-to-end development of new features and services, from architecture through deployment and monitoring.
• Improve our developer workflows by strengthening CI/CD pipelines, reducing manual steps, and increasing test coverage.
• Collaborate with cross-functional teams (product, ops, data) to understand real-world needs and ship tools that directly support program delivery in the field.
• Debug and resolve production issues across our stack, with a focus on root cause analysis and long-term fixes.
• Advocate for sustainable engineering practices, including testing, documentation, and monitoring
• Help shape our tech roadmap with an eye toward scale, maintainability, and recipient experience

What you’ll bring:

• Exceptional alignment with GiveDirectly Values and active demonstration of our core competencies: emotional intelligence, problem solving, project management, follow-through, and fostering inclusivity. We welcome and strongly encourage applications from candidates who have personal or professional experience in the low-income and/or historically marginalized communities that we serve.
• Language Requirement: English
• 4+ years of industry experience creating production-caliber software and systems
• Experience with backend architecture: databases, cloud services, APIs
• Experience building infrastructure to deploy software
• Experience with strongly-typed, object-oriented programming such as Java, C#, Go, etc. and scripting languages such as Python, Ruby, etc.
• High degree of ownership and autonomy - you proactively advocate for ways to improve systems and constantly leave our codebase in a better state than you found it
• Strong analytical skills and communication - able to break down complex problems, describe technical trade-offs, and collaborate with cross-functional partners (e.g. technical program managers, product managers)
• Bonus: Experience using Python and AWS in a production environment
• Bonus: experience with payments/financial software and/or experience with microservice/serverless architecture
