Software Engineer III

Zinnia is seeking a highly skilled Software Engineer III with full-stack expertise, focusing on back-end and API development while also contributing to front-end tasks. This role involves designing, developing, and maintaining scalable, secure, and high-performance software systems for Zinnia’s enterprise platforms. You will thrive in a hands-on environment, tackling complex problems, writing high-quality code, and collaborating with cross-functional teams. We are looking for individuals passionate about modern software engineering, cloud-native development, and API-driven architectures who can deliver robust solutions and uphold team best practices.

Key responsibilities include designing, developing, documenting, and maintaining scalable, secure, and reusable software components and applications across back-end services/APIs and front-end interfaces. You will contribute to defining and implementing coding standards, design patterns, and testing practices. A significant part of the role involves building and maintaining enterprise APIs, managing their lifecycle, and integrating them with API gateways for enhanced traceability, monitoring, security, and analytics. You will also support improvements to the software development and deployment lifecycle to boost speed, quality, and reliability. Automation of unit, functional, integration, and contract tests is crucial, as is writing high-quality, maintainable, and performant code with active participation in peer code reviews. Collaboration with architects, product managers, and engineers to align solutions with enterprise goals is essential, as is integrating applications and APIs with enterprise Identity and Access Management (IAM) solutions. Continuous innovation and staying current with emerging technologies to improve scalability, performance, and developer experience are encouraged.

Required qualifications include a Bachelor’s or Master’s degree in Computer Science or a related field, and over 6 years of professional software development experience. Proficiency in .NET (C#) and JavaScript/TypeScript is essential, along with experience in modern frameworks like NestJS for back-end and React, Angular, or Next.js for front-end. Proven experience in designing, developing, and maintaining scalable software systems and versioned APIs is required. Hands-on expertise in developing applications in cloud-native environments, specifically with AWS services such as Lambda, EC2, S3, API Gateway, DynamoDB, SNS/SQS, and RDS, is necessary. Experience with API gateways (e.g., Apigee, Kong) and API lifecycle management, as well as event-driven architecture and pub/sub messaging patterns with platforms like Apache Kafka, is expected. Strong knowledge of relational databases (MS SQL, Oracle, PostgreSQL) and NoSQL databases (MongoDB, DynamoDB, Cassandra) is required. Working knowledge of DevOps practices (CI/CD, provisioning, monitoring) and containerization technologies (Docker, Kubernetes) is needed. A solid understanding of software engineering principles, object-oriented design, and design patterns, coupled with experience in an Agile/Scrum environment, is vital. Excellent problem-solving, troubleshooting, and communication skills, with the ability to collaborate in a distributed team, are essential. A commitment to continuous learning and staying updated with the latest software development technologies is important.

Nice-to-have qualifications include experience with Java and related technologies, and knowledge of the Life Insurance & Annuities domain.
