Job description

About Us and the Role

EffectiveSoft is a fast-growing software development company delivering innovative solutions to clients around the world, with a strong focus on the US market. Headquartered in sunny San Diego, California, we’ve built a team of over 300 talented professionals across multiple countries. Our success comes from a deep commitment to results and long-term partnerships built on trust.


We’re launching a transformative partnership with a new US-based client in the data quality and enrichment space who is embarking on a bold modernization initiative. This client is transitioning from a fragmented legacy ecosystem to a fully cloud-native, scalable platform built on AWS. The transformation is not just technical – it’s strategic, touching every layer of infrastructure, product delivery, and operational efficiency.


As a DevOps Engineer, you’ll be at the center of this journey, helping architect the systems and practices that will support long-term growth, automation, and innovation. You’ll play a critical role in designing and implementing the infrastructure and DevOps strategy that enables this transformation. This includes solving deep-rooted challenges around scalability, release orchestration, cost optimization, and environment consistency – while laying the foundation for a secure, observable, and automated cloud environment. This is a hands-on role with strategic influence, ideal for someone who thrives in high-autonomy environments and enjoys solving complex infrastructure challenges.


Tech Stack Snapshot: • Cloud Provider: AWS • Compute & Orchestration: ECS, Fargate, Elastic Beanstalk, Lambda, EC2 (legacy) • Storage & Data: S3, RDS (PostgreSQL), Aurora • IaC: Terraform (selective use, expanding) • Containers & Configuration: ECR, AppConfig • Messaging & Coordination: SNS, SQS • Monitoring & Logging: CloudWatch, RDS Console • CI/CD: GitHub Actions, manual deployments (transitioning to full automation)


Key Responsibilities:

Infrastructure & Environment Management

• Design and provision isolated environments for development, QA, staging, and production using AWS best practices. • Standardize infrastructure provisioning using Terraform, ensuring consistency and version control across services. • Improve IAM role management and automate access provisioning to support secure and flexible operations. • Define ownership and review protocols for infrastructure changes and environment templates. CI/CD & Deployment Automation • Architect and implement unified CI/CD pipelines across a diverse service landscape using GitHub Actions. • Integrate automated testing, linting, security scanning, and deployment validation into every pipeline. • Formalize and enforce a branching strategy to improve release management, collaboration, and CI/CD stability. • Introduce rollback strategies (e.g., blue/green or canary deployments) to support safe and resilient releases. • Establish isolated QA environments to support pre-production testing and reduce deployment risk. Cloud Architecture & Scalability Engineering • Implement auto-scaling policies based on real-time load metrics using ECS, Fargate, and Lambda. • Conduct performance simulations to validate scaling behavior and forecast capacity needs. • Address architectural bottlenecks, particularly in the database layer (e.g., write throughput, replication latency). • Define and monitor non-functional scalability requirements (NFRs) and continuously improve system responsiveness.


Monitoring, Observability & Incident Response

• Introduce full-stack observability tools (e.g., Datadog, AWS X-Ray, New Relic) for distributed tracing and performance insights. • Implement centralized logging using ELK stack or CloudWatch Logs Insights. • Define and monitor SLOs/SLIs for critical services and set up alerting and dashboards for ingestion pipelines and APIs. • Participate in incident response and postmortems, driving continuous improvement in system reliability and recovery. Security & Compliance • Enforce secure configuration management and secrets handling across environments. • Support SoC2 and GDPR compliance efforts through infrastructure-level controls and audit readiness. • Evaluate and implement network segmentation, VPC isolation, and firewall rules to enforce boundaries and reduce risk.


Cloud Cost Optimization & Governance

• Audit AWS usage and apply cost optimization techniques including reserved instances, savings plans, and storage tiering. • Implement lifecycle policies for S3 and other storage services to manage data retention and cost. • Build dashboards to visualize resource usage, monitor cost trends, and align infrastructure decisions with budget targets.


Collaboration & Enablement

• Work closely with engineering teams to unblock delivery and improve deployment confidence. • Support QA and product teams by stabilizing environments and improving release visibility. • Champion DevOps best practices across teams and foster a culture of automation, ownership, and continuous delivery.


Required Qualification:

• 5+ years of experience in DevOps, Site Reliability Engineering, or Cloud Infrastructure roles, ideally within high-availability, distributed systems. • Deep expertise in AWS, including hands-on experience with ECS, Lambda, RDS, S3, IAM, and messaging services like SNS/SQS. • Proficiency in Terraform for infrastructure provisioning and lifecycle management, with a strong understanding of version control and CI/CD integration. • Hands-on experience with GitHub Actions, including pipeline design, deployment automation, and quality gate implementation. • Strong grasp of CI/CD principles, branching strategies, and deployment methodologies (e.g., blue/green, canary). • Solid understanding of containerization and orchestration using Docker, Fargate, and EKS, with experience managing container images via ECR. • Familiarity with monitoring and observability tools, such as CloudWatch, Datadog, ELK stack, and AWS X-Ray, with the ability to define and track SLOs/SLIs. • Working knowledge of security best practices, including secrets management, IAM policies, and infrastructure controls aligned with SoC2 and GDPR compliance. • Excellent communication and collaboration skills in English, with the ability to work cross-functionally and support engineering, QA, and product teams.


Preferred Qualifications:

• Experience with PostgreSQL performance tuning, replication strategies, and backup automation. • Exposure to data pipelines and ETL workflows, especially in batch or event-driven architectures. • Familiarity with cloud cost optimization techniques, including reserved instances, storage tiering, and usage forecasting. • Experience supporting QA automation, test environments, and release validation workflows.


Why choose us?

• We’re a company where curiosity fuels everything - from new ideas to personal growth. • We believe that common sense sits at the heart of everything we do. It helps us stay focused, make smart decisions, and move fast without the noise. • We trust each other to follow through and own the outcome, no micromanagement, just real commitment. • You’ll be heard here, even when you challenge the status quo. Because courage matters. Who dares — wins.
