Job description

On-site Position
Who You Are

You are an innovative and detail-oriented Full-Stack Engineer with a passion for building reliable, secure, and scalable applications. You thrive in complex enterprise environments, enjoy collaborating with diverse teams, and are committed to continuous learning and technical excellence.

You’re someone who finds energy in problem-solving, optimizing cloud architectures, and delivering high-quality software that directly impacts millions of users. You take ownership of your work, enjoy mentoring others, and value process discipline — especially in environments that demand precision, performance, and compliance.

If you want to grow with a mission-driven company, contribute to world-class projects with global clients like JP Morgan Chase, and help elevate Latin American tech talent to its fullest potential, this is the role for you.

Who We Are

MAS means “more” in Spanish — and that’s what we stand for. We believe in providing more opportunities, more inclusion, and more impact.

Founded by a Latina engineer from Medellín and based in Tampa, Florida, MAS Global Consulting is a 100% Hispanic and woman-owned company, recognized as a Great Place to Work and one of the Fastest-Growing Companies in the US.

We connect top Latin American talent with North American clients to build digital, data, and cloud solutions. Our teams are currently helping world-leading organizations like JP Morgan Chase, Johnson Controls, and Dell to modernize platforms, deliver innovation, and scale digital transformation.


How You Will Make Impact

As a Full-Stack Java Developer, you will design, build, and optimize microservices and customer-facing applications that process massive volumes of secure transactions daily. You will work directly with Chase engineers under a time-and-materials engagement, embedded in agile delivery teams.

Your contributions will drive real impact by improving system performance, enhancing observability, and enabling data-driven financial solutions at scale.

Key Responsibilities
  • Design and develop RESTful APIs and microservices using Java (11+), Spring Boot, and Spring Cloud frameworks.
  • Implement event-driven architectures with Kafka (producers, consumers, schema management, and streaming).
  • Deploy and manage services on AWS ECS/Fargate, using Terraform or CloudFormation for Infrastructure-as-Code and Spinnaker for CI/CD automation.
  • Integrate and maintain data flows with Cassandra, AWS S3, or Spark-based pipelines.
  • Collaborate with frontend teams using React or Angular to deliver seamless, full-stack solutions.
  • Leverage Python for automation, data validation, or integration scripting (nice-to-have).
  • Ensure quality through Test-Driven Development, automated testing, and continuous integration practices.
  • Partner with DevOps and QA teams to enhance resilience, scalability, and performance across distributed systems.
  • Participate in sprint planning, design reviews, and retrospectives while following Agile/Scrum practices.
  • Champion best practices in security, code quality, and documentation, ensuring compliance with Chase’s standards.
You Have:
  • BS/BA degree or equivalent experience in Computer Science, Engineering, or related field.
  • 7+ years of experience building enterprise-grade applications using Java / Spring Boot.
  • Proven experience developing and deploying microservices on AWS Cloud (ECS, Fargate, Lambda).
  • Solid understanding of Kafka, Docker/Kubernetes, and distributed system design.
  • Hands-on experience with CI/CD pipelines (Spinnaker, Jenkins, or GitHub Actions).
  • Experience with frontend frameworks like React or Angular for full-stack delivery.
  • Familiarity with Cassandra, SQL/NoSQL databases, and data streaming concepts.
  • Working knowledge of Python3 for automation or data processing (nice-to-have).
  • Exposure to observability tools like Datadog, Splunk, or Dynatrace for monitoring and troubleshooting.
  • Experience working in Agile environments and collaborating in cross-functional teams.
  • Excellent communication skills — able to explain technical concepts to both engineers and product stakeholders.
Bonus Skills (Nice to Have):
  • Knowledge of Apache Spark, Flink, or data engineering concepts.
  • Familiarity with financial services, regulated environments, or compliance-heavy systems.
  • Experience integrating AI/ML-powered recommendation systems or event-driven personalization logic.
  • Awareness of performance testing, NFR validation, and resilience patterns (DLQ, retries, fallback).
Benefits
  • Health: Medical, dental, and vision coverage.
  • Time Away: Vacation, holidays, wellness days, and parental leave.
  • Financial: 401(k), basic life, and AD&D insurance.
  • Growth: Ongoing technical learning, certification reimbursement, and leadership development.
Equal Opportunity Statement

At MAS Global, diversity and inclusion are at the heart of our identity. We celebrate individuality and believe that everyone deserves a fair opportunity to grow and succeed. We are proud to be a woman-owned, minority-led company and an equal opportunity employer.
