Job description

About Nclusion

Nclusion is on a mission to provide traditional financial services to 1.5 billion people worldwide without access today. Without a secure way to save, invest, or transfer money, individuals are not empowered to accumulate short or long-term wealth. We’re changing that by bridging the gap between traditional banking and the communities that need it most.

About the Role

At Nclusion, engineers own their own testing. The Quality Enablement & Developer Tooling team’s job is to make that as fast and reliable as possible. As our first Senior Software Engineer on this team, you’ll design and own the foundations: the testing SDKs that engineers use daily, and the K6 load testing framework that teams rely on to validate performance before it reaches production. This is a high‑leverage IC role. You’ll set the baseline standards the org builds on, while giving teams the flexibility to go further. The work you do here will multiply across every engineering team at Nclusion.

What You’ll Own

• Design and maintain Nclusion’s testing SDK: the shared library engineers use to write and run automated tests across the stack.
• Build and own the K6 load testing framework, enabling teams to define performance thresholds and validate them in CI before every release.
• Set org‑wide baseline standards: test structure, coverage expectations, and naming conventions, while giving teams flexibility to build on top of them.
• Integrate both frameworks into GitHub Actions CI/CD pipelines and keep them stable, fast, and reliable.
• Write documentation and examples that make self‑service the default; work with teams directly when they need it.

What You Bring

• 7+ years of professional experience in platform engineering, developer tooling, or a related discipline.
• Deep expertise designing SDKs or shared libraries that other engineers have adopted: you think carefully about API ergonomics, developer experience, and abstraction regardless of language.
• Hands‑on K6 experience: you’ve written load test scripts with meaningful ramp strategies and SLA‑tied thresholds, not just boilerplate.
• Strong CI/CD fluency: GitHub Actions pipeline design, test stability, flakiness debugging.
• A developer‑first mindset: the engineers using your tooling are your customers, and you design accordingly.
• The credibility and communication skills to influence engineering teams you don’t manage. You can make the case for a standard without being dogmatic about it.

Benefits and Perks

• 401k with a match!
• Medical Insurance
• Dental Insurance
• Vision Insurance
• Competitive compensation & equity – We believe in sharing success.
• Flexible PTO – We focus on impact, not tracking vacation days. We encourage a minimum of 14 days.
• In‑office lunch, team events & culture
