• Lead a team of engineers designing, developing and operating integration services that connect our customers’ internal systems with Flip (e.g. HR systems, knowledge bases) • Push forward our integration platform, a dedicated runtime environment for custom integrations (based on Kubernetes and ArgoCD). • Our tech stack is mostly JVM-based (Kotlin, Micronaut), some components are written in Python and JavaScript. • We work remote within international (mostly European), cross-functional agile teams. • We develop software following modern software engineering practices (API first, code reviews, automated tests, MR environments for exploratory testing before a merge, and some tasteful experimental AI augmentation). • We deploy (Kubernetes, Helm) and monitor (Grafana, Sentry, Mixpanel) our services within the teams, with the support of a separate team of SREs for on-call duty. • Join customer calls together with your product manager to understand their specific problems and empower your team to build solutions that cover a majority of customer contexts. • Take charge on technical topics that are important to you, driving significant decisions, and seeking alignment across teams within our backend guild.

• Design, develop and deliver high quality code to production within a short development cycle. • Collaborate with engineering, product and cross functional teams to devise optimal engineering solutions. • Travel to conferences and events for client support (when possible)

• Own and evolve core payment services for online (CNP), device-based EMV (CP), digital wallets (e.g., Apple Pay, Google Pay), and payment facilitator/orchestration flows. • Modernize and improve existing components into more cloud-native, distributed architectures using containers on AWS/Azure. • Own and extend end-to-end payment workflows: authorization, capture, void, refund, tokenization, clearing, funding, settlement, and multi-source reconciliation. • Expand capabilities for international payments, including multi-currency and cross-border flows. • Integrate with payment service providers (PSPs), EMV card readers, and device SDKs using secure, standards-based messaging. • Improve and maintain CI/CD pipelines in GitHub Actions (automated builds, tests, security scans, packaging, deployments). • Design and evolve test automation strategy, covering domain-level logic, API contracts, and integration with external processors and devices. • Strengthen platform reliability through observability (metrics, logs, traces), fault-tolerant design, and automated operational workflows. • Partner with Product, Security, Compliance, and Operations to deliver features that balance customer experience, regulatory requirements, risk, and operational robustness. • Mentor engineers, lead design and architecture discussions, and influence the long-term strategy for the payments platform.
