How you'll help us achieve it

Wave is now the largest financial institution in Senegal and Côte d'Ivoire, with millions of users, growing rapidly year-on-year. And, we’re still in the early days of our product roadmap and potential impact on people’s everyday lives.

We’re looking for an experienced security engineer who’s independent, excited about getting things done, and ready to hit the ground running. You'll primarily be responsible for our application security, working with our product teams to work on new systems to enhance our security posture. Our customers trust us with their money, and you’ll be at the forefront of making sure we retain that trust!

This broadly scoped role will allow you to get your hands on many different types of security projects, from direct application security to helping our infrastructure team think about security for our databases. 

Some experience with common industry certifications like ISO-27001 and PCI-DSS would be beneficial, although you won’t be expected to run or oversee audits.

Our to-do list changes constantly, but here are some recent projects and activities:

• Centralise application-level login and permissions enforcement
• Configure and utilise external SIEM solutions to monitor our infrastructure
• Help us increase our posture around secret management
• Security review of our public-facing APIs
• Partner with teams across Wave to define secure guardrails, supporting investigations and incident response
• Work with our IT Team to fix any non-conformities found during audits by central banks and ISO certification

Our stack (prior experience is a strong plus, but not required):

• backend: Python 3 (+ mypy)
• API layer: GraphQL
• android frontend: Kotlin/Jetpack
• iOS frontend: Swift/SwiftUI
• web frontend: TypeScript/React
• database: Postgres/CockroachDB
• infrastructure: GCP/Terraform
• orchestration: Kubernetes

Key Details

• This is a fully remote role. Candidates must be based in one of our talent hub countries (UK, Spain, Kenya and Ghana) or in one of our operating markets in Africa including Senegal, Côte d'Ivoire, or Burkina Faso.
• Wave provides a yearly $1,200 stipend to support coworking meetups with teammates.
• Remote team members are expected to travel to our operational markets (e.g. Senegal or Côte d'Ivoire) at least once a year. Exceptions apply, but we’ve found this key to understanding our users and product.
• Our salaries are competitive and are calculated using a transparent formula. For this role, depending on your level and location, we offer a salary of up to $227,900 USD, plus a generous equity package.
• Major benefits:
  • Subsidized health insurance for you and your dependents and retirement contributions (both vary from country to country).
  • 6 months of fully paid parental leave and subsidized fertility assistance.
  • Flexible vacation, with most folks taking between 21-30 days exclusive of statutory holidays.
  • $10,000 annual charitable donation matching.

Requirements

• Minimum of 5 years of professional experience with a minimum of 2 years of it spent in a security-related role.
• Strong Experience with Python.
• Fluent English.

You might be a good fit if you

• Are excited about finding the right balance between security and velocity. 
• Push through hard problems without giving up.
• Have experience remediating non-conformities.
• Enjoy helping other engineers understand and implement secure patterns.
• Are not afraid to take on complicated systems.
• Are excited to work on lots of different security-related work, from audits to code refactors. 
• Work to make things easier for the next engineer who will touch your code.
• Always try to improve as a programmer and colleague.
• Are interested in security-focused source code review and penetration testing.
• Have an interest in growing and mentoring a team.

About engineering at Wave

We care about the big picture. We don’t hire engineers to just ship tickets. We hire them to solve problems. That means caring deeply about outcomes, understanding context, and jumping in wherever something’s broken, even if it’s technically “not your area.” When we see problems, inefficiencies, or opportunities to make something better, we act. We dig into operational issues, clarify fuzzy product specs, or step into unfamiliar code to help unblock teammates.

We move as fast as possible. Speed matters. It lets us try things quickly, get feedback early, and course-correct while it’s cheap. So we write small PRs. We aim for MVPs. We leave TODOs and file follow-ups. We don’t over-perfect v1. That said, we’re building a financial product. Some things—like money movement, correctness, or security—deserve more caution.

We like boring technology. We favor tools that are reliable, well-understood, and easy to debug. This keeps us focused on solving meaningful problems instead of wrestling with unpredictable infrastructure. If a new technology helps us move faster, build safer, or solve a real need, we’ll consider it. But we don’t adopt tools just because they’re new—we adopt them because they’re right.

Simplicity is a strategy. It lets us focus our energy where it matters most: serving our users.

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
