pWallee is a Swiss payment technology company. Our platform processes online, mobile and point of sale payments for thousands of merchants across Europe.

You manage a team of engineers and you set the technical direction for one of the most critical parts of our platform. You report to the Head of Engineering and work inside the OmniPayments tribe alongside the other tech leads. We are looking for a co-builder: someone who supports the tribe and the company in building new things the proper way, not someone who only manages a backlog. /p h3Tasks /h3 h3Technical leadership /h3 ul liOwn the architecture and technical roadmap of the payment modules, including all acquirer and scheme integrations. /li liLead new acquirer integrations end to end: analysis, design, implementation, certification, rollout and monitoring. /li liManage technical debt deliberately in a large, mature codebase built on an in-house framework on top of the Spring Framework. Improve it through incremental, low-risk steps rather than rewrites. /li liDrive platform evolution: we run Java 21 today and will move to Java 25, and we are shifting toward event-driven, fault-isolated services. /li liSet and uphold engineering standards: design reviews, code quality, automated testing, observability. /li /ul h3People leadership /h3 ul liLead, coach and grow a squad of engineers distributed across Switzerland, Lithuania and Ukraine /li liRun regular 1:1s, give honest feedback, build development plans and actively support career growth. /li liHire and onboard new engineers together with the Head of Engineering. /li liSpread knowledge deliberately through documentation, pairing and rotation, so that no module depends on a single person. /li /ul h3Delivery and production /h3 ul liOwn production quality for your modules: monitoring, alerting, incident response and root cause analysis. /li liTreat availability, correctness and traceability as features. Payments are mission critical and money movement must always be explainable. /li liProvide validated estimates and technical analysis as input to our planning process (PI Planning and Definition of Ready). /li liBalance new features against reliability and debt reduction, and make those trade-offs explicit to stakeholders. /li /ul h3Collaboration and stakeholders /h3 ul liWork closely with your Product Manager on discovery, shaping and prioritization. You bring a product mindset: you care about the merchant problem, not only the ticket. /li liPartner with the Head of Engineering on tribe-level goals, capacity and escalations. /li liBuild together with the other tech leads in the tribe: shared standards, cross-squad initiatives, joint problem solving. /li liInterface with the architecture team and DevOps on designs, infrastructure and operational topics. /li liSupport customer support with technical escalations and give sales fast, honest feasibility answers. /li /ul h3Requirements /h3 h3What we are looking for /h3 ul li10+ years of software engineering experience, including 3+ years leading a team. /li liA university degree in Computer Science or a closely associated discipline is required. /li liDeep Java and Spring expertise.

Exposure to ISO 8583 or ISO 20022 is a plus. /li liA track record of reducing technical debt in production systems without stopping delivery. /li liSoftware architecture skills: system design, clear written decisions (ADRs), pragmatic trade‑offs, and the ability to review and challenge designs from others. /li liProduction orientation: you have carried operational responsibility, run incidents and improved the system afterwards. /li liExperience running services in the cloud. We use AWS services and Kubernetes. /li liGenuine interest in people leadership: you get energy from making other engineers better. /li liA builder's leadership spirit: you support the Head of Engineering, involve your peers and help the tribe and the whole company move forward together. /li liYou possess a fluent command of the English language. /li /ul h3Nice to have /h3 ul liFamiliarity with e‑commerce ecosystems and payment plugins (Shopify, Lightspeed, Shopware, Magento, WooCommerce and similar) /li liExperience with event‑driven architectures and migrating synchronous legacy flows to asynchronous ones. /li liJVM performance analysis: thread dumps, blocked thread detection, GC and connection pool tuning. /li liExperience in a regulated or certified environment (PCI DSS, financial services). /li liExperience leading distributed or multi‑country teams. /li /ul h3Benefits /h3 ul liA modern and secure working environment in the heart of the city of Winterthur with opportunities for personal growth and development /li liBe part of an agile, young team and make a lasting impression on our products with your ideas /li liYou will play a decisive role in shaping products in a dynamic company and work together with leading companies in the financial industry on international projects. /li liFlexible structures and flat hierarchies /li li4 weeks Remote Working per Year /li liFree coffee, tea and soft drinks /li liTeam events and regular social gatherings /li /ul h3Interested? /h3 pThen we look forward to getting to know you and shaping the future of payments together. /p #J-18808-Ljbffr
