Jobs at Djinni

We’re building next-generation payment infrastructure for high-volume, high-risk merchants - fast, intelligent, and built for scale.
As our Lead Payments Engineer, you’ll own the architecture behind mission-critical payment flows, deep processor integrations, and the systems that power merchant success.

Your mission is to design, scale, and evolve a payment ecosystem that can outperform legacy processors in both speed and intelligence.
You’ll lead the development of our gateway integrations (with a major focus on RocketGate), build merchant-facing dashboards, and create resilient systems that handle disputes, fraud controls, and high-volume settlement pipelines - all while shaping the engineering culture of a rapidly growing fintech startup.

• Design high-availability, high-throughput backend systems built for scale
• Define and own the technical roadmap
• Mentor and grow an engineering team focused on speed, precision, and accountability
• Collaborate with operations, compliance, and commercial teams to deliver features merchants rely on

• You bring deep experience in payments — especially card-not-present and high-risk environments
• You’ve built or scaled transactional systems handling heavy throughput
• You naturally take ownership and thrive in fast, high-trust environments
• You communicate clearly, think strategically, and enjoy solving complex system challenges
• You enjoy leading teams while staying hands-on with architecture and development

• Leadership:
  Track record of managing engineering teams and owning technical strategy

Nice to Have

• Crypto payment processing experience
• Machine-learning or rules-based fraud detection systems
• Exposure to offshore acquiring and multi-geo merchant onboarding
• Experience in ISO/MSP environments

With Us You’ll Have

 • Fully remote setup with a flexible schedule
