Key Responsibilities:
Feature Development: Develop and maintain high-performance backend services and APIs primarily using GoLang and GraphQL.
Performance Optimization: Implement and refine low-latency coding practices to ensure high-speed data processing and minimal response times.
Cloud Integration: Deploy and manage services within AWS, utilizing Lambda, Fargate, and DynamoDB.
Production Support: Participate in the full software development lifecycle, including on-call rotations and monitoring system performance (latency, availability).
CI/CD & Automation: Support and improve our Jenkins pipelines and automated deployment processes.
Collaborative Engineering: Work in a polyglot environment where Java is relevant, assisting with service integrations and code reviews.
Problem Solving: Identify and resolve technical debt and performance bottlenecks within the platform
Required Qualifications:
Technical Proficiency: 2+ years of professional software development experience, with a strong focus on GoLang. Experience with Java is also highly relevant.
Latency-Critical Engineering: Proven ability to write efficient, concurrent code and tune applications for low-latency requirements.

Database: Working with DynamoDB (basic schema design and querying).
DevOps Tools: Familiarity with Jenkins for CI/CD and a "you build it, you run it" approach to software.
SRE Awareness: Understanding of core SRE principles, such as SLIs/SLOs and observability.
Preferred Skills:
AWS Certification: Holding or working toward an AWS Associate-level certification.
Industry Context: Experience or interest in working with payment networks like Visa, Mastercard, and American Express.
Hands-on AWS: Direct experience configuring cloud resources beyond just deploying code.
