Role Summary

We are looking for a hands-on Full Stack Engineer to design, develop, and maintain scalable, cloudready, enterprise applications in a financial services environment. The ideal candidate is a strong Java engineer with solid frontend experience (Angular), who has worked on distributed microservices, eventdriven architectures (Kafka), and modern CI/CD pipelines on AWS or another major cloud.

Key Responsibilities

Design, develop, and maintain highperformance web applications using Angular (preferably Angular 17+), TypeScript, HTML, CSS, and RxJS.
Build, test, and integrate RESTful APIs and backend services using Java, Spring Boot, and related frameworks (Spring MVC, Java EE).
Implement secure, scalable backend logic following best practices for authentication, authorization, and application security (OAuth2, Azure AD, JWT or similar).
Design and build cloudready, distributed microservices and eventdriven systems using Apache Kafka.
Work extensively with relational databases (Oracle, MySQL, SQL Server) and write performant SQL/PLSQL; experience with OLAP platforms (Snowflake, Redshift, DuckDB) is a plus.
Contribute to and consume UI design systems, including design tokens, Angular Material, Bootstrap, Highcharts, AG Grid, and related frontend libraries.
Apply TestDriven Development (TDD) and Acceptance TestDriven Development (ATDD) practices, including unit, integration, and endtoend testing.
Build and maintain CI/CD pipelines using tools such as Jenkins, uDeploy (or equivalent), Git, Maven, JUnit, Docker, Kubernetes, and related DevOps tooling.
Collaborate closely with Product Owners, Architects, Tech Leads, and crossfunctional teams to refine requirements, propose technical solutions, and deliver highquality features.
Participate in code reviews, enforce coding standards, and contribute to continuous improvement of engineering practices.

Required Skills and Qualifications

6 9 years of professional experience as a Full Stack or Backend Engineer building enterprisescale applications (3 5 and 10+ considered for the right fit).
Strong expertise in Java and Spring Boot, with handson experience building microservices and RESTful APIs.
Solid frontend experience with Angular (ideally Angular 17+), TypeScript, HTML, CSS; React experience is a plus.
Experience designing and operating eventdriven systems with Apache Kafka.
Strong RDBMS skills (Oracle/MySQL/SQL Server) and confident writing complex SQL; PLSQL experience is a plus.
Experience with CI/CD pipelines and DevOps tools: Git, Jenkins, Maven, Docker, Kubernetes, uDeploy (or similar), Sonar, Artifactory/Nexus, JMeter or similar.
Experience deploying and operating applications on AWS or another major cloud (EC2, Lambda, S3, IAM, KMS, CloudWatch or equivalents).
Familiarity with TDD/ATDD and automated testing tools/frameworks such as JUnit, Jest, Karma, Cypress, Playwright, Pytest, Karate is highly valued.
Good knowledge of software engineering best practices across the SDLC: coding standards, code reviews, source control, build processes, testing, and operations.
Strong communication, problemsolving, and teamwork skills, with the ability to work independently with minimal direction.

Nice to Have

Experience in financial services or asset management domains.
Exposure to Python and frameworks such as Django, Flask, or FastAPI.
Experience with design systems and UI design token implementation.
Exposure to LLMs/AI systems (OpenAI / Azure OpenAI / Gemini), agents, and LangGraphstyle workflows.

Job Responsibilities

Design, develop, and maintain scalable, cloudready web applications using Java, Spring Boot, and Angular in a microservices and eventdriven architecture.
Build, consume, and optimize RESTful APIs, ensuring reliability, performance, and secure integration with upstream and downstream systems.
Implement robust, secure backend services including authentication, authorization, and data access layers, following firm security and compliance standards.
Develop rich, responsive UI components in Angular using TypeScript, HTML, CSS, and established design systems (e.g., Angular Material, design tokens, shared UI libraries).
Work with messaging platforms such as Kafka to build eventdriven workflows and integrate with distributed services across the ecosystem.
Write clean, testable code and apply TDD/ATDD practices, creating and maintaining unit, integration, and endtoend test suites using tools like JUnit, Cypress, and related frameworks.
Collaborate closely with Product Owners, Architects, Tech Leads, and other engineers to refine requirements, design technical solutions, and break work down into incremental deliverables.
Participate in code reviews, provide constructive feedback, and help enforce engineering best practices, coding standards, and quality guidelines.
Configure and maintain CI/CD pipelines (e.g., Jenkins/uDeploybased) to support automated builds, tests, and deployments to nonprod and production environments.
Monitor application health and performance using logging and observability tooling, triage production issues, and contribute to root cause analysis and remediation.
Work with relational databases (e.g., Oracle, SQL Server, MySQL) to design schemas, write efficient SQL/PLSQL, and tune queries for performance and scalability.
Contribute to continuous improvement of the team s tooling, processes, and documentation, and mentor junior engineers where appropriate.
