You will be instrumental in building and evolving a cloud-native, event-driven integration platform based on AWS, Kafka, Go and Python, leveraging canonical data models, asynchronous messaging, observability, and resilient orchestration patterns. The platform processes high-volume business-critical events while providing end-to-end visibility, reliability, security, and scalability. 

This role requires deep expertise in distributed systems, event-driven architecture, microservices, data engineering, and cloud-native development. You will contribute to the design and implementation of Service Layer foundation capabilities including messaging, observability, orchestration, data migration, reconciliation, canonical data management, and operational tooling. 

Key responsibilities:

• Design, develop, and operate real-time event-driven integration services using Golang and Python.
• Build and enhance the Service Layer platform that orchestrates Quote-to-Cash workflows across enterprise applications.
• Design and implement canonical data models, transformation frameworks, validation rules, and integration contracts that standardize communication across multiple business systems.
• Develop scalable Kafka-based event processing solutions with support for retries, idempotency, sequencing, replay, and fault recovery.
• Build secure REST APIs through AWS API Gateway and integrate with SaaS platforms / Enterprise Applications.
• Build and support large-scale ETL, migration, reconciliation, and data-quality solutions using AWS Glue, Step Functions, Snowflake, PostgreSQL, and ClickHouse.
• Design and implement observability, monitoring, alerting, and operational dashboards to enable end-to-end workflow visibility and supportability.
• Define and enforce engineering standards, secure-by-design principles, cloud best practices, data governance and non-functional requirements for resilience, scalability, and supportability. 
• Collaborate with distributed engineering teams and cross-functional stakeholders to translate business requirements into scalable data solutions delivered within agreed timelines.
• Participate in architecture reviews, production support, root-cause analysis, performance optimization, and operational readiness activities.

Must Have Skills:

• Strong hands-on experience in Golang and Python for building scalable backend services, event-driven integrations, orchestration workflows, and data processing solutions.
• Strong experience designing and building cloud-native applications on AWS, including AWS Lambda, API Gateway, S3, RDS/Aurora PostgreSQL, DynamoDB, SQS, SNS, EventBridge, IAM, CloudWatch, VPC, and related serverless architecture patterns.
• Strong experience designing and operating event-driven and asynchronous systems using Kafka, AWS MSK, RabbitMQ, or equivalent messaging technologies.
• Strong understanding of distributed systems architecture, including scalability, resiliency, fault tolerance, idempotency, retry patterns, dead-letter queues, message replay, and eventual consistency.
• Strong experience with PostgreSQL, ClickHouse, relational databases, and NoSQL databases such as DynamoDB, including data modelling, query optimization, and performance tuning.
• Hands-on experience designing and implementing RESTful APIs, integration services, and enterprise system interfaces using secure API design principles.
• Experience building and enforcing canonical data models, data contracts, transformation layers, and validation frameworks for enterprise integrations.
• Hands-on experience building and supporting high-availability, business-critical applications on AWS with strong focus on performance, reliability, and operational supportability.
• Experience with CI/CD pipelines, automated testing, code quality, and secure software delivery practices, using tools such as GitLab CI, Jenkins, SonarQube, Trivy, Semgrep etc.
• Experience with observability, monitoring, and operational analytics, using CloudWatch, Grafana, Datadog, Prometheus, OpenTelemetry, or equivalent platforms.
• Strong understanding of cloud security and secure-by-design principles, including IAM, OAuth2, JWT authentication, encryption at rest and in transit, Secrets Manager, vulnerability management, audit logging, and compliance controls.
• Strong problem-solving skills with experience in production support, incident management, root cause analysis, and performance optimization within large-scale distributed environments.

Qualifications: 

• Bachelor's degree in Computer Science, Engineering, Information Technology, or related discipline.
• 7+ years of software engineering experience, with at least 3+ years focused on data engineering and distributed data platforms.
• 3+ years building cloud-native solutions on AWS.
• 3+ years of experience working with Golang, Python, AWS Service, and Kafka in production environments.
• Experience designing and supporting highly available enterprise integration platforms.

Nice to have:
