About the Role
We’re hiring a Software Development Engineer III (SDE III) who loves owning features end-to-end and can move seamlessly between backend architecture and frontend delivery.
Must-have skills:
Expert-level Node.js and deep hands-on experience with MongoDB (complex queries, aggregations, indexing, sharding)Strong production experience with Redis (caching, rate-limiting, pub/sub, distributed locks)Proven ability to build responsive, high-quality UIs with any modern framework (Vue.js is a big plus; React/Angular also perfectly fine)Real-world experience designing and running microservices on KubernetesSolid track record shipping scalable, reliable systems on any major cloud platform (GCP, AWS, or Azure)You write clean, modular, reusable code — on both backend and frontend
What you’ll own (true full-stack impact):You’ll join the Sub-Accounts team that powers the entire end-business layer — handling hierarchy, permissions, data isolation, reporting, and performance for over 2 million end businesses (our agencies’ customers) — making sure every single one of them gets a fast, secure, and seamless experience on our platform.
This is genuine end-to-end ownership:Design and deliver new sub-account features from API to pixel-perfect UIBuild scalable microservices and event-driven workflowsOptimize performance, cost, and reliability across the entire stackHarden security and access control at every layerReduce tech debt and improve observability (logs, metrics, tracing)Work directly with product and customers to ship experiences people loveYou’ll split your time roughly 50/50 backend ↔ frontend — deep systems work one sprint, beautiful UI the next.
If you get excited about building complex hierarchy & permission systems, love shipping complete features fast, and want to make sub-accounts feel effortless for thousands of users — this role is made for you.
Responsibilities
- Own feature delivery from concept to production for the Sub-Accounts platform — design APIs, implement backend logic, and build clean, responsive frontend experiences (any modern UI framework; Vue.js experience is a big plus).Build and evolve highly scalable, performant microservices using Node.js, MongoDB, Redis, and event-driven patterns running on Kubernetes and GCP.
- Proactively hunt down and fix systemic issues (race conditions, deadlocks, memory leaks, timeouts, data inconsistencies) across the sub-accounts hierarchy and permissions system.
- Drive performance and cost optimizations — query tuning, intelligent caching, indexing strategies, and GCP cost reduction without sacrificing speed or reliability.
- Ruthlessly reduce technical debt through refactoring, improving test coverage, and eliminating anti-patterns in both backend and frontend code.
- Strengthen security at every layer — RBAC/ABAC enforcement, tenant isolation, audit trails, rate limiting, secrets management, and input validation.
- Improve observability across the stack — meaningful logs, metrics, distributed tracing, and alerts that make incidents easy to debug in real time.
- Work hand-in-hand with QA from day one: review test cases, give live demos during QA handover, and resolve feedback quickly.
- Build internal tools, scripts, and automation that accelerate development, testing, and deployment cycles for the entire team.
- Actively pair with teammates, share knowledge, conduct code reviews, and help unblock others.
- Participate in on-call rotation and own incident resolution for the sub-accounts services you build.
- This is a hands-on individual contributor role where you’ll write production code daily, ship complete features fast, and directly shape how thousands of agencies and resellers experience our platform.
- If you love end-to-end ownership and want to make multi-account management feel effortless and bulletproof — this is your role.
Requirements
- 4–7 years of hands-on engineering experience with proven exposure to scale (high TPS, large datasets, or complex multi-tenant/multi-account systems)Expert-level Node.js and a strong habit of writing clean, modular, reusable codeDeep expertise with MongoDB (complex schemas, aggregation framework, indexing, sharding, change streams)
- Solid production experience with Redis (caching, rate-limiting, pub/sub, distributed locks, session management)Real-world experience building and operating microservices on Kubernetes (deployments, services, configmaps, helm, basic troubleshooting)
- Strong hands-on experience with any major cloud provider (GCP, AWS, or Azure) – you know how to use managed services for containers, queues, caches, serverless, and databases effectivelyComfortable building responsive, high-quality UIs with any modern frontend framework (Vue.js is a big plus; React or Angular experience works perfectly too)
You’ve shipped and supported large-scale, mission-critical systems that stayed stable under heavy load. You’re passionate about modular architecture, obsess over performance and GCP cost optimization, and can seamlessly jump into the frontend to deliver complete, polished features.
If multi-account hierarchy, permissions, tenant isolation, and making complex things feel simple excites you — we want you on the Sub-Accounts team.
Preferred Experience
- Experience with AI Tools and contributions to open-source tools, internal platforms or engineering blogs
- NestJS or Express.js experience
- Elasticsearch for advanced search/filtering use cases
