Staff Backend Engineer | JVM

Accountabilities: You will take ownership of backend technical strategy and platform health, helping engineering teams deliver secure, scalable, and high-performing services while establishing shared standards and practices across the organization.

• Backend Architecture & Business Impact

• Drive backend technical direction and architectural decisions across multiple engineering squads.

• Deliver measurable business improvements in areas such as payment success rates, customer onboarding, marketplace conversion, and engineering delivery speed.

• Collaborate with Product, Risk, and Growth teams to improve high-volume revenue flows, including credit decisioning, onboarding, merchant checkout, payments, repayments, and collections.

• Reduce latency, transaction failures, and manual workarounds while improving customer and merchant experiences.

• Own the end-to-end health of the platform, including reliability, scalability, performance, security, infrastructure cost, and operational simplicity.

• Platform Foundations & Engineering Standards

• Design and promote shared engineering foundations, including service templates, reusable libraries, messaging and event standards, CI/CD pipelines, and release practices.

• Partner with Platform and Site Reliability Engineering teams, as well as product engineering squads, to drive adoption of consistent backend practices.

• Define and support Service Level Objectives (SLOs) and error budgets based on service criticality.

• Lead root-cause analysis for complex production incidents and ensure corrective actions prevent recurring issues.

• Translate security and quality requirements—including authentication, authorization, personal data protection, OWASP, PCI, secrets management, and dependency scanning—into automated CI checks and engineering standards.

• Establish testing expectations across contract, integration, and other critical application flows.

• AI-Native Engineering

• Drive the adoption of agentic coding tools and AI-assisted development practices across backend engineering teams.

• Establish conventions, skills, specification templates, and CI safeguards for tools such as Claude Code and Factory Droid, or equivalent solutions.

• Ensure AI-generated code meets security, reliability, and quality standards before deployment.

• Encourage specification-driven development and continuously improve team conventions and tooling based on practical experience.

• Technical Leadership & Collaboration

• Write and drive adoption of technical RFCs and Architecture Decision Records (ADRs) covering service boundaries, data ownership, event contracts, consistency, idempotency, testing, and security.

• Build alignment among Engineering, Product, Risk, Security, and Data stakeholders around technical priorities and trade-offs.

• Communicate complex architectural decisions clearly to technical teams and senior leadership, connecting engineering investments to business outcomes.

• Influence engineering practices through technical credibility, clear documentation, and constructive collaboration.

• Mentor Senior Engineers and support their development toward Staff Engineer and Tech Lead responsibilities.

• Contribute to technical hiring, interviewer calibration, engineering reviews, and initiatives that strengthen the organization's engineering culture.

• Participate in incident leadership and the on-call culture, supporting systems responsible for financial transactions and credit decisions.

Requirements :

The ideal candidate is a highly experienced backend engineer with a strong JVM background, a proven record of designing distributed systems at scale, and the ability to influence technical decisions across multiple teams. You should combine architectural judgment with business awareness, strong communication, and a practical approach to engineering execution.

• 15+ years of professional experience building production software.

• 8+ years of experience owning the architecture of large-scale distributed backend systems.

• 4+ years in a Staff Engineer, Principal Engineer, or Software Architect role, driving technical decisions across multiple engineering squads.

• Deep expertise in the JVM ecosystem, including Java, Kotlin, or Scala, and Spring Boot.

• Strong experience with SQL and PostgreSQL, Redis, messaging technologies such as Kafka, SQS, or RabbitMQ, event-driven architecture, AWS, and Kubernetes.

• Demonstrated ability to design and scale complex architectures, including service boundaries, data consistency, messaging patterns, and zero-downtime deployments.

• Proven experience defining technical standards or shared platform capabilities adopted by at least four engineering teams.

• Experience writing RFCs and ADRs, securing stakeholder alignment, and driving technical proposals through implementation and adoption.

• Strong judgment when balancing delivery speed, reliability, infrastructure cost, and long-term maintainability.

• Experience leading significant architectural modernization or re-engineering initiatives, such as decomposing monoliths or redesigning core domains, while maintaining product delivery and service availability.

• A track record of defining SLOs and delivering measurable improvements in availability, p95/p99 latency, throughput, or infrastructure costs.

• Experience establishing security practices across teams, including authentication, authorization, personal data protection, OWASP, and PCI requirements.

• Strong understanding of testing strategies across unit, integration, contract, and end-to-end testing.

• Experience leading complex production incident investigations and implementing long-term reliability improvements.

• Hands-on experience with agentic coding tools such as Claude Code, Factory Droid, or similar solutions as part of regular development workflows.

• Experience establishing AI-assisted engineering practices at team or organizational level, including conventions, specification templates, and CI safeguards.

• Ability to connect backend architecture decisions to business outcomes involving credit risk, payments, conversion, and operational costs.

• Strong communication and stakeholder management skills, including the ability to influence Engineering Managers, Product, Risk, Security, and Data teams without direct authority.

• Experience owning high-volume payment, credit decisioning, ledger, or onboarding systems within fintech, banking, lending, or marketplace environments.

• Understanding of regulated financial systems, including idempotency, reconciliation, auditability, compliance, and data integrity.

• Experience mentoring engineers and helping senior technical talent progress into broader leadership roles.

Nice to Have:

• Familiarity with API gateways, GraphQL, Backend-for-Frontend (BFF) layers, and third-party integrations such as payment processors and credit bureaus.

• Experience with end-to-end authentication flows, including OAuth, token issuance, and token refresh.

• Experience shaping technical hiring standards, engineering review processes, or technical communities and guilds.

Benefits :

• Competitive compensation.

• Equity participation, offering meaningful ownership in the company's growth.

• Opportunity to work on products that improve access to financial services and transform how people shop, pay, and bank.

• Significant technical ownership and the opportunity to shape platform architecture and engineering strategy.

• High-impact role in a fast-growing organization with substantial opportunities for professional growth.

• Opportunity to collaborate with an international team of experienced professionals.

• A culture centered on ownership, technical excellence, collaboration, and continuous improvement.
