Job description

Job Overview:

We are seeking a highly skilled Senior Software Engineer to join our dynamic development team. This role is integral to the success of our internal actuarial solution cloud platform. As a Senior Software Engineer, you will start by supporting existing applications and, based on performance, will transition to building and deploying cloud-based solutions. This is a nearshore position with the potential for offshoring, primarily focusing on candidates from Latin America.

Key Responsibilities:

• Full-Stack Development: Independently create API-based web applications from concept to finished product with a cloud-first emphasis.
• Technical Problem Solving: Implement solutions for complex technical challenges, using advanced problem-solving skills and creativity.
• Collaboration: Work closely with product stakeholders and development teams, utilizing strong communication skills to articulate problems and solutions effectively.
• Cloud Deployment: Design, develop, test, deploy, and support API-based systems, emphasizing industry best practices and cloud-first deployment strategies.
• Legacy Support: Provide ongoing support for legacy systems while transitioning to new cloud-based solutions.
• Continuous Improvement: Seek and implement continuous quality improvements for supported systems.
• Mentorship: Mentor and coach junior team members, fostering a culture of knowledge sharing and innovation.
• Task Management: Manage individual tasks and timelines with minimal supervision, ensuring timely and efficient delivery of solutions.

Technical Requirements:

• Must-Have: Node.js (required) for backend development, and proficiency in React for frontend development.
• Hands-on experience with both Relational databases (e.g. PostgreSQL, SQL Server) and NoSQL databases (e.g. DynamoDB, MongoDB), with strong SQL query skills.
• Very strong hands‑on experience with IaC Terraform, including module design, multi‑environment management (dev/staging/prod), and managing different Terraform state types (local state, remote state via S3 + DynamoDB locking, and workspace‑based state isolation), with CI/CD pipeline integration.
• Proficiency in AWS cloud services, with deep hands‑on experience in serverless architecture including end‑to‑end Lambda Functions (trigger design, handler implementation, error handling, DLQ/retry logic) and Step Functions for multi‑step serverless workflow orchestration.
• Solid observability skills using Amazon CloudWatch (metrics, alarms, logs) for monitoring Lambda usage, concurrency, and scaling behavior.
• Strong understanding of API Gateway design and best practices: RESTful resource structure, authentication (Cognito/Lambda authorizers), throttling, usage plans, versioning, and CORS configuration.
• Demonstrated ability to make sound serverless architecture decisions, including when Lambda is the wrong tool (long‑running jobs, heavy compute, stateful workloads) and how to decompose functions using single‑responsibility and event‑driven principles.
• Working knowledge of AWS IAM, including authoring and managing trust policies and permission policies (inline and managed), applying least‑privilege principles for roles, users, and service‑to‑service access.
• Understanding of AWS security policies and best practices, including resource‑based policies, service control policies (SCPs), and security guardrails within cloud deployments.
• Experience with message queue and streaming services such as Amazon SQS or Apache Kafka for decoupled, event‑driven architectures.
• Proficiency in .NET / C# (preferred) for backend services and integrations.
