Who We're Looking For
We are looking for engineers who share our passion for technology and rise to meet hard technical challenges. Individual contributors who thrive in a collaborative culture and a strong technical environment — self-starting, dynamic, and quick to pick up new technologies in order to deliver working solutions with minimal direction.
This is a backend-heavy full-stack role: you should be an engineer who is at home in distributed, server-side systems first, with the range to also work competently across the stack when a feature calls for it.
What You'll Do
We are seeking a Full-Stack Software Engineer to work closely with the architecture team on enhancements to Provenir's cloud-native, microservices-based decisioning engine (rules/graph-based execution).
This role requires deep, hands-on backend expertise and extends into full ownership of features end to end — from service design through UI integration and deployment.
• Design, build, and evolve microservices for Provenir's decisioning engine using Core Java and Spring Boot.
• Design and implement synchronous and asynchronous REST APIs that power decisioning workflows across the platform.
• Apply multi-threading and performance-tuning techniques to keep high-throughput decisioning services fast and reliable at scale.
• Build and maintain event-driven integrations using Kafka and ActiveMQ (or equivalent message queuing technologies) to support distributed, asynchronous processing.
• Model and manage data across relational and NoSQL stores (MySQL, MongoDB) using ORM tools such as Hibernate, Ebeans, or OpenJPA.
• Practice test-driven development, writing and maintaining unit tests as a core part of the delivery process.
• Containerize and deploy services with Docker and Kubernetes, working within a single-region, multi-AZ
AWS deployment architecture, and contribute to CI/CD pipelines (Git, GitHub Actions, Jenkins, Terraform, Datadog).
• Own features across the full SDLC — design, testing, implementation, deployment, and maintenance — in partnership with the architecture team.
• Build and maintain Angular or React or any frontend framework components and modules that surface decisioning workflows and configuration screens, integrating cleanly with backend REST APIs.
• Contribute to responsive UI work using TypeScript, HTML5/CSS3, and frameworks such as Material-UI, Bootstrap, or Tailwind.
What's Required
Experience & Education
• Minimum of 5 years of professional software development experience — this is a firm minimum for the role.
• Bachelor's or Master's degree in Computer Science, Computer Engineering, or a related field.
• Minimum 5+ years of hands-on experience with Core Java, Spring Boot, Angular or React or any frontend framework, AWS, multi-threading, and performance tuning.
• Proven experience designing, building, and deploying microservices architectures in cloud environments.
• 4+ years designing and developing synchronous and asynchronous REST web services.
• Experience with message queuing technologies such as Kafka, ActiveMQ, or equivalent.
• 4+ years working with ORM tools (Hibernate, Ebeans, or OpenJPA) across relational and NoSQL databases (MySQL, MongoDB).
• 4+ years of test-driven development and unit testing practice.
• Solid grounding in OOA/OOD and design patterns — knowing where, why, and how to apply them.
• Hands-on experience with AWS, containerization and orchestration (Docker, Kubernetes), and CI/CD tooling (Git, GitHub Actions, Jenkins, Terraform, Datadog).
Full-Stack / Frontend Exposure
• Working knowledge of Angular or React or any frontend framework, with hands-on experience integrating front-end applications with backend REST services.
• Practical, hands-on experience with HTML5, CSS3, and responsive UI frameworks such as Material-UI, Bootstrap, or Tailwind.
Nice to Have
• Experience with Scrum/Agile development methodologies.
• Unix/Linux operating system knowledge.
• Broader exposure to event-driven and distributed system design beyond core messaging integration.
• Exposure to systems supporting ML/DL/AI model training, testing, or execution within a production product stack.
Why You Should Join Us
Our employees are empowered to be curious, forward-thinking engineers. We ask them to explore the uncharted and build the unimagined — that's what makes Provenir unique.
We offer comprehensive health and wellness plans. You'll enjoy paid time off and company holidays, flexible and remote-friendly options, along with benefits to plan for your future.
