Our mission is to empower financial freedom through technology, offering innovative and transparent digital banking solutions.\nJoin us in reshaping the financial landscape!\nAbout the Role\nAs Lead Software Engineer, you’ll be one of the technical authorities on how Snappi’s systems are designed and built. You’ll own the architecture that power our bank: domain boundaries, API contracts, integrations and the services behind our products and operations. You’ll also build it yourself, with AI agents as part of your daily toolchain.\nThis is a senior individual contributor role. You’ll work with both our engineering partners and our in-house team of software, ML, data, cloud operations and CRM engineers. Your job is to connect them into one coherent engineering system.\nWhere you’ll make an impact\nWe have several systems to design, build, expand, and the order will follow the business priorities. You’ll contribute to various domains such as:\nCredit decisioning. A decision engine that combines our in-house predictive models with policy rules, data sources and human review. It must be explainable, auditable and safe to change.\nOperations automation. Workflows and agents that remove manual work across onboarding, KYC/KYB, payments operations, risk and customer support.\nProduct development. The services that integrate and power our bank, linking our channels with our partner products, with business logic in the right place.\nIntegrations. Clean, well-bounded integrations with core banking, card processing, open banking and third-party providers.\nData and AI platform. Getting data, models and AI agents into production reliably, together with our Data and ML teams.\nWhat you’ll do\nDesign the systems. Define and evolve Snappi’s target architecture: bounded domains, contracts, event flows and decision services. Make it secure, resilient and auditable, as a bank needs to be.\nBuild what you design. Write production code and reference implementations, using AI coding agents to move fast without lowering the bar.\nShape our AI-native SDLC. Put spec-driven development and agent-assisted delivery into practice, and help curate the instructions, skills and guardrails our agents rely on.\nSet the engineering standard. Review designs and code from in-house and partner engineers, and make sure quality is built into the codebase and enforced by CI/CD.\nWork across platforms. Partner with Cloud Ops, Data and ML so features ship end to end, from infrastructure as code to models in production.\nTranslate the business. Work with Product, Credit, Risk and Operations to turn banking needs into simple, well-bounded technical solutions, and help decide what to build first.\nRequirements\nExtensive experience designing and building complex, distributed, production-grade systems, and owning their architecture end to end.\nStrong system design skills: domain modelling, API and event-driven design, data consistency, security, resilience and observability.\nComfort working across very different problem spaces, such as decision systems, workflow automation and customer-facing services, while keeping the overall architecture coherent.\nDeep expertise in at least one modern backend ecosystem, and the ability to work across languages and technologies (our stack includes .NET, Go, Python).\nDaily, hands-on use of AI coding agents, with a clear view on making their output reliable through specs, context, tests and review.\nA track record of making codebases testable and automating delivery through CI/CD.\nComfort with ambiguity and shifting priorities, and the judgement to sequence work for the most business impact.\nAbility to lead through influence across partners, product and engineering, with a strong ownership mindset.\nFluent English.\nNice to have\nExperience in banking, payments, lending or card processing.\nExperience building decision or rules engines (credit decisioning, fraud, risk scoring), or integrating ML models into regulated decisions.\nExperience with workflow orchestration (e.g. Temporal, Durable Functions, Camunda) or building production AI agents.\nKnowledge of regulatory and security frameworks such as DORA, PSD2/SCA or the EU AI Act.\nGreek.\nWhy Join Snappi?\nWe foster a culture of innovation, trust, and continuous development. We focus on solutions and results. Your work will directly shape the future of banking, making financial services more accessible and impactful. If you're ready to make a difference, we’d love to hear from you!\nBenefits\nAt Snappi, we invest in your well-being, growth, and work-life balance with a benefits package designed to support both your personal and professional journey:\nCompetitive salary \nHybrid work flexibility \n37-hour work week \nExtra paid time off \nMedical & Life insurance coverage \n24/7 Mental Health support for you and your family \nEmployer-sponsored pension plan \nExclusive perks with special rates on banking products \nOngoing learning & career development opportunities \nTeam activities & events to foster bonding, well-being, and a strong company culture \nPlus, for parents:\nDaycare allowance to help cover preschool costs \nAdditional school monitoring days \nSavings plan for your children \nWe believe diversity makes us stronger.
