Team:

Lending -- Platform & Core Services

Reports to:

Principal Engineer (Lending)

About the role

We're hiring a hands-on Tech Lead (Backend) to join the Lending platform. You'll be the technical owner for backend microservices: designing and building resilient, secure, and observable services, guiding architectural decisions and collaborating across product, front-end, and cloud teams. This role combines development, architecture, mentoring and delivery leadership.

What you'll do

Lead design and development of backend microservices (Spring Boot) that power lending flows and integrations. Own service architecture, APIs, contract definitions (OpenAPI/Swagger) and versioning strategy. Design and implement secure authentication & authorization patterns (OAuth2, JWT, mTLS, SAML, etc.). Build and operate services on Kubernetes: deployments, config/secret management (e.g. K8s Secrets, HashiCorp Vault), horizontal scaling and health checks. Define CI/CD pipelines, automated testing, and release strategies for safe, repeatable delivery. Collaborate with front-end and product teams to define APIs, SLAs, and integration contracts. Work with cloud infrastructure and platform teams on load balancing, network design, observability, incident response and cost-conscious architecture. Integrate and secure third-party services (payment providers, fraud engines, ID providers, document services). Coach and mentor engineers; lead technical design reviews and runbooks; evangelise best practices. Evaluate and propose AI/ML-assisted solutions where they add value (e.g., document analysis, automation, assistive features).

Must-have skills & experience

Strong Java/Spring Boot experience (production microservices). Comfortable with JDK 17 or later. Deep understanding of microservices architecture patterns: service discovery, circuit breakers, retries, idempotency, sagas/transactions. Practical experience deploying and operating services on Kubernetes (Helm, kustomize or similar). Experience with secrets/config management (K8s Secrets, Vault, SOPS, Parameter Store). Solid knowledge of authentication & security (OAuth2/OIDC, JWT, TLS, secure API design). Experience designing and publishing OpenAPI/Swagger contracts and working with contract-first approaches. Familiar with CI/CD tooling and pipelines (Jenkins/GitHub Actions/GitLab CI/ArgoCD etc). Good understanding of cloud components (load balancers, VPC/subnetting, managed services, observability stacks). Experience integrating with third-party APIs and handling production-grade reliability. Strong communication skills and the ability to translate technical trade-offs to stakeholders.

Nice-to-have

Terraform (infrastructure as code) experience. Azure platform experience (AKS, Azure Load Balancer, Key Vault etc). Salesforce integration experience (APIs, data flows, authentication with Salesforce). Experience or interest in applying AI/ML to product problems (document classification, extraction, recommendations). Familiarity with API gateways (Kong, Istio, AWS API Gateway), service meshes (Kong Mesh, Istio), and event-driven patterns (Kafka). Front-end awareness: ability to collaborate on UI/API contracts and understand UX implications. Knowledge of performance tuning, JVM profiling and capacity planning.

Personal attributes

Pragmatic, delivery-focused and obsessed with reliability and observability. Collaborative -- you enjoy working cross-functionally and mentoring peers. Comfortable making trade-offs and documenting reasoning for future teams. Customer-centric mindset -- you put user and business outcomes first.
