Senior Backend Engineer

Chargeflow · modiinmaccabimreut

Description This is not your typical engineering role. If you're looking to pick up tickets, follow specs, and write “clean services”- this isn’t for you. But if you care about building systems that think , if you use AI to move faster than everyone else, and if you want real ownership over complex, high-scale problems - keep reading. What we're actually building At Chargeflow, we’re building systems that don’t just process data, they make decisions. Real-time, high-stakes, at scale. Fraud isn’t static. It evolves all the time so our systems need to evolve faster. That means combining backend architecture, data, and AI into something smarter than traditional SaaS. What you’ll actually do Design and build the core systems behind real-time fraud detection Work on everything from ingestion pipelines to decision engines Own what you build - from idea to production to iteration Deal with scale, edge cases, failures, and ambiguity (a lot of it) Use AI as part of your daily workflow — not as a gimmick, but as leverage Help figure out better ways to build software in this new era Requirements What we care about (beyond buzzwords) You’ve built real systems, not toy projects or just CRUD. You understand distributed systems because you’ve dealt with their pain. You can go deep when needed on performance, architecture, and trade-offs. You don’t wait for perfect specs, you figure things out. You care about how things work, not just that they work. AI is not optional here You already use tools like Codex, Claude Code, Cursor - daily You don’t just autocomplete code - you think with AI You’ve built small tools / automations / experiments with LLMs You know AI makes mistakes, and you know how to catch them You’re curious about how engineering is changing, and you want to be ahead of it What you’ll get here Real ownership (not “ownership” in slides) Hard problems with real impact A team that moves fast and expects you to keep up Freedom to rethink how things should be built — not just maintain what exists A chance to become a significantly stronger engineer by working differently Stack (for context, not as a checklist) Node.js / TypeScript Distributed, event-driven architecture Kafka AWS MongoDB + Postgres Containers (Docker, Kubernetes / ECS) If you want to build, lead, and rethink how engineering works - we should talk. Super-competitive compensation for those who fit!
