With a company culture rooted in collaboration, expertise and innovation, we aim to promote progress and inspire our clients, employees, investors and communities to achieve their greatest potential. Our work is the catalyst that helps others achieve their goals. In short, We Enable Possibility℠.
We're looking for a passionate, detail-oriented Senior 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 — including the external-facing APIs our partners rely on.
This role goes beyond feature delivery. You'll help shape the technical strategy of the platform, influence architectural direction, and partner directly with product and growth teams to turn business objectives into engineering outcomes — from improving how customers discover and purchase coverage to scaling the systems behind new products and markets. You thrive in event-driven, distributed architectures and have a strong instinct for writing clean, observable, and resilient code.
WHAT YOU'LL DO
Technical Leadership & Architecture
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
Full Stack Delivery
Design, develop, and maintain full stack features across React/Angular frontends and Node.js backend microservices
Build and evolve RESTful and event-driven APIs — both internal services and external-facing APIs consumed by our partners — 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
Investigate and resolve complex bugs and production incidents end-to-end — from the UI down to the service layer
Strategy & Growth
Partner with product, design, and growth teams on growth initiatives — customer acquisition, activation, and conversion funnel improvements — translating experiment ideas into shippable, measurable features
Contribute to experimentation and A/B testing efforts, using data and metrics to validate impact and inform the next iteration
Align technical decisions with business strategy — weighing near-term growth opportunities against long-term platform health, and communicating those trade-offs clearly to stakeholders
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
Participate in code reviews, architectural discussions, and contribute to engineering best practices
Collaborate closely with product managers, designers, and other engineers across the stack
OUR TECH STACK
Frontend: React (Jest), Angular 2+ (Jasmine & Karma), Next.js, Razzle, TypeScript
Backend: Node.js microservices (Koa, NestJS)
Database: MongoDB
Messaging: AWS SNS & SQS (event-driven async flows)
Cloud: AWS
E2E Testing: Playwright
Monitoring: AWS CloudWatch, Sentry
AI Tooling: Claude Code (AI-assisted, agentic development)
CI/CD: CircleCI
WHAT WE'RE LOOKING FOR
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., CloudWatch, Sentry, or similar) — 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
A business-minded approach to engineering — comfort connecting technical work to company goals, growth metrics, and customer outcomes
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
BONUS POINTS
Experience in InsurTech, FinTech, or other regulated industries
Experience supporting growth engineering — experimentation platforms, A/B testing frameworks, funnel analytics, or conversion optimization
Experience with agentic coding and AI-assisted development workflows — using tools like Claude Code to accelerate delivery while maintaining quality
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
