Software Engineer Level III – Fullstack

📋 Description

• We are seeking a Full Stack Engineer who is adept at navigating both frontend and backend development.

• In this role, you will contribute to our user-facing applications built with React/Angular as well as our Node.js microservices, playing a key part in building, scaling, and maintaining the systems that drive Thimble's platform.

• You excel in event-driven, distributed architectures and possess a strong aptitude for writing clean, observable, and resilient code.

• Lead the design of complex, high-scale backend platforms, taking ownership of the entire lifecycle from requirements gathering through implementation and iteration.

• Establish architectural principles and engineering best practices that elevate the quality across the team.

• Make significant design decisions that involve thoughtful trade-offs between scalability, performance, cost, and long-term maintainability.

• Create data models that are structured, efficient, and designed to evolve with the product.

• Design, develop, and maintain full stack features that span React/Angular frontends and Node.js backend microservices.

• Build and enhance RESTful and event-driven APIs, ensuring they are thoroughly tested, well-documented, and ready for production.

• Collaborate with MongoDB to design schemas, write efficient queries, and manage data at scale.

• Develop and maintain event-driven workflows utilizing AWS SNS and SQS to reliably manage asynchronous system flows.

• Implement monitoring and observability tools by setting up metrics, alerts, dashboards, and distributed tracing to ensure system health.

• Engage in code reviews, participate in architectural discussions, and contribute to engineering best practices.

• Investigate and resolve complex bugs and production incidents from the UI down to the service layer.

• Conduct technical research and propose solutions to new and ambiguous engineering challenges.

• Independently plan and manage your work, breaking down large features into well-defined tasks and driving them to completion.

• Work closely with product managers, designers, and other engineers throughout the stack.

⛳️ Requirements

• Over 5 years of professional full stack development experience, with a proven history of leading system design for complex, high-scale platforms.

• Demonstrated ability to define architectural principles and promote engineering best practices within a team.

• Experience in making impactful design decisions with clear reasoning regarding trade-offs such as scalability versus cost, performance versus maintainability, and speed versus reliability.

• Strong data modeling capabilities — designing schemas and structures that are clean, efficient, and scalable.

• Proficient in Node.js — building and maintaining production-level microservices.

• Solid experience with MongoDB, including schema design, indexing, aggregation pipelines, and query optimization.

• Practical experience with event-driven architectures, particularly with AWS SNS and SQS or equivalent pub/sub and message queue systems.

• Expertise in React and/or Angular 2+ for developing and maintaining modern frontend applications.

• Familiarity with monitoring and observability tools (e.g., Datadog, New Relic, CloudWatch) — instrumenting services, creating dashboards, configuring alerts, and utilizing distributed tracing to diagnose issues.

• Experience in writing tests across the stack, including unit, integration, and E2E tests (Jest, Jasmine/Karma, Playwright or similar).

• General understanding of AWS services beyond messaging, including S3, IAM, Lambda, and EC2.

• Excellent research and investigative abilities — capable of systematically navigating unfamiliar codebases and ambiguous technical challenges.

• Strong problem-solving mindset — thorough, communicative, and effective under pressure.

• Capable of independently planning and owning complex features from design to production.

• Strong communication skills and comfort in a remote, asynchronous work environment.

• Experience in InsurTech, FinTech, or other regulated industries.

• Knowledge of Infrastructure as Code (Terraform, AWS CDK, or similar tools).

• Experience with CI/CD pipeline configuration, particularly with CircleCI.

• Direct involvement in building a new application from scratch or leading a significant migration (e.g., framework or database migration).

• Familiar with proprietary or complex internal component libraries on the frontend.

• Contributions to open source projects.

🏝️ Benefits

• Employees are allowed to work remotely.
