Job Description

Summary:

  • Work Mode: Hybrid
Responsibilities:
  • Act as the primary technical point of contact embedded with company teams to gather requirements, scope solutions, and define technical sequencing.
  • Rapidly prototype and deliver production-ready applications using Java or Python that solve real trading, risk, and operational problems.
  • Balance tradeoffs between scope, speed, and quality to meet aggressive company timelines without compromising system integrity.
  • Own Discovery & Scoping engagements, translating ambiguous business asks into clear technical specifications and delivery plans.
  • Demonstrate strong business acumen: understand ROI/AI impact, enterprise workflows, stakeholder management, and establish continuous product feedback loops with company stakeholders.
  • Produce clear technical documentation and communicate complex architecture decisions to both engineering and non-technical business audiences.
  • Architect and build scalable, resilient full-stack applications using Java (Spring Boot/Spring Framework, Microservices) and/or Python (FastAPI/Flask), tailored to enterprise financial workflows.
  • Leverage Python for rapid prototyping, data analytics, pricing/risk calculations, and automation scripts where appropriate.
  • Apply strong data modeling and query optimization skills across Oracle Database, MS SQL Server, and MongoDB.
  • Ensure solutions are built with enterprise-grade security, auditability, and regulatory compliance across both Java and Python codebases.
  • Design, build, and maintain CI/CD pipelines using Tekton (Red Hat OpenShift Pipelines) and Jenkins to enable rapid, reliable, and auditable deployments for both Java and Python services.
  • Deploy and manage containerized workloads on OpenShift/Kubernetes, applying infrastructure-as-code best practices.
  • Be fluent in at least one major cloud platform and demonstrate the ability to deploy infrastructure as code reliably and repeatably.
  • Own production readiness: ensure what is built won't break or behave unexpectedly once live including monitoring, alerting, rollback strategies, and incident response support.
Requirements:
  • Minimum 8 years of professional software engineering experience, with demonstrable experience as a Full-Stack Developer transitioning into an FDE-style, customer-facing delivery role.
  • Expert-level proficiency in Java (Core Java, Spring Boot, Microservices architecture, REST/gRPC APIs) and/or strong production experience in Python (FastAPI/Flask, data processing libraries).
  • Ability to work across both Java and Python codebases, or demonstrated ability to ramp up quickly on the second language.
  • Hands-on experience with Tekton/OpenShift Pipelines and Jenkins for CI/CD pipeline design and management.
  • Strong database expertise across Oracle Database, MS SQL Server, and MongoDB, including performance tuning and schema design.
  • Demonstrated knowledge of DevOps practices: containerization (Docker/OpenShift/Kubernetes), infrastructure as code, and cloud deployment (AWS/Azure/GCP at least one).
  • Excellent communication, technical writing, and stakeholder management skills; comfortable working directly with business stakeholders.
  • High agency, ownership mindset, and comfort operating with ambiguity in fast-paced client-facing environments.
Preferred Skills:
