2026-7878 Software Engineer Level II - Fullstack (Nightshift)

Company Description

AGSI was incorporated in April 2016. We are committed to supporting the goals of Arch divisions through exceptional service delivery. We pride ourselves on maintaining flexibility and responsiveness to adapt to business unit and industry demands while focusing on sound project management. We are dedicated to growing and developing our employees as we build strong teams with strategic leadership.

Job Description

We're looking for a Full Stack Engineer who is equally comfortable working across the frontend and backend. You'll contribute to both our user-facing React/Angular applications and our Node.js microservices, helping us build, scale, and maintain the systems that power Thimble's platform. You thrive in event-driven, distributed architectures and have a strong instinct for writing clean, observable, and resilient code.

• Lead end-to-end system design for complex, high-scale backend platforms — owning the full lifecycle from requirements through implementation and iteration
• Define architectural principles and engineering best practices that raise the quality bar across the team
• Make high-impact design decisions involving deliberate trade-offs between scalability, performance, cost, and long-term maintainability
• Design data models that are well-structured, efficient, and built to evolve alongside the product
• Design, develop, and maintain full stack features across React/Angular frontends and Node.js backend microservices
• Build and evolve RESTful and event-driven APIs, ensuring they are well-tested, documented, and production-ready
• Work with MongoDB to design schemas, write efficient queries, and manage data at scale
• Develop and maintain event-driven workflows using AWS SNS and SQS to manage asynchronous system flows reliably
• Instrument services with monitoring and observability tooling — setting up metrics, alerts, dashboards, and distributed tracing to ensure system health
• Participate in code reviews, architectural discussions, and contribute to engineering best practices
• Investigate and resolve complex bugs and production incidents end-to-end — from the UI down to the service layer
• Conduct technical research and propose solutions to new and ambiguous engineering challenges
• Plan and manage your own work independently, breaking down large features into well-scoped tasks and driving them to delivery
• Collaborate closely with product managers, designers, and other engineers across the stack

Qualifications

• Frontend: React (Jest), Angular 2+ (Jasmine & Karma), Next.js, Razzle, TypeScript
• Backend: Node.js microservices
• Database: MongoDB
• Messaging: AWS SNS & SQS (event-driven async flows)
• Cloud: AWS
• E2E Testing: Playwright
• Monitoring: Datadog (APM, logs, dashboards, alerts)
• CI/CD: CircleCI
• 5+ years of professional full stack development experience, with a track record of leading system design on complex, high-scale platforms
• Proven ability to define architectural principles and drive engineering best practices across a team
• Experience making high-impact design decisions with clear reasoning around trade-offs — scalability vs. cost, performance vs. maintainability, speed vs. reliability
• Strong data modeling skills — designing schemas and structures that are clean, efficient, and built to scale
• Strong proficiency in Node.js — building and maintaining production microservices
• Solid experience with MongoDB — schema design, indexing, aggregation pipelines, and query optimization
• Hands-on experience with event-driven architectures, specifically AWS SNS and SQS or equivalent pub/sub and message queue systems
• Proficiency in React and/or Angular 2+ for building and maintaining modern frontend applications
• Experience with monitoring and observability tools (e.g., Datadog, New Relic, CloudWatch) — instrumenting services, creating dashboards, configuring alerts, and using distributed tracing to diagnose issues
• Experience writing tests across the stack — unit, integration, and E2E (Jest, Jasmine/Karma, Playwright or similar)
• General understanding of AWS services beyond messaging — S3, IAM, Lambda, EC2, or similar
• Excellent research and investigation skills — able to navigate unfamiliar codebases and ambiguous technical challenges systematically
• Strong problem-resolution mindset — thorough, communicative, and effective under pressure
• Ability to plan and own complex features independently from design through to production
• Strong communication skills and comfort working in a remote, async-friendly environment
• Experience in InsurTech, FinTech, or other regulated industries
• Knowledge of Infrastructure as Code (Terraform, AWS CDK, or similar)
• Experience with CI/CD pipeline configuration — particularly CircleCI
• Direct involvement in building a new application from the ground up or leading a large-scale migration (e.g., a framework or database migration)
• Familiarity with homegrown or complex internal component libraries on the frontend
• Contributions to open source projects
