[Hiring] Senior Full Stack Engineer @Throne Labs

Role Description

As a Senior Full-Stack Engineer at Throne, you'll own features end-to-end across our API (Node.js), web dashboard (React/Next.js), and mobile app (React Native) - from an ambiguous product idea through a measured technical design to production. This is a high-autonomy role on a small team: you'll make architecture decisions, write the specs the team builds from, and partner directly with product to turn priorities into well-scoped work. We are looking for an experienced engineer who thrives in a fast-moving startup environment and is comfortable with day-to-day uncertainty.

This role is eligible to work remotely within the United States. Minimal domestic travel should be expected.

The base salary range for this position is $150,000 - $200,000. Actual compensation will depend on a candidate's applicable experience, skills, and geographic location. This role is also eligible for a comprehensive benefits package, including equity.

What you'll work on

• A cloud-connected IoT fleet: real-time device state and cloud-to-device commands over AWS IoT Core / MQTT.
• Real-time operational surfaces for the team running the fleet across markets.
• Data-driven optimizations and automations as we scale from flagship market to many.

Tech Stack

• Node.js + Express (TypeScript)
• React + Next.js (TypeScript)
• React Native
• PostgreSQL, TimescaleDB, Redis
• Event-driven and background processing (SQS, BullMQ), WebSockets
• AWS: IoT Core, ECS/EKS, Lambda, Cognito, SQS, RDS, CloudWatch

Responsibilities

• Own features end to end: design, scope, prototype, build, test, ship, and refactor across API, web, and mobile.
• Translate ambiguous product requirements into clear technical scope - data models, API contracts, and implementation options with their trade-offs.
• Drive architecture decisions for new and existing services to support our constantly increasing scale, and back them with evidence (measured performance, capacity, failure modes).
• Lead feature and story refinement; research and analyze the impact of new capabilities before they are built.
• Partner proactively with product to clarify priorities, resolve ambiguity, and turn them into deliverable tasks. Raise the engineering bar through code review and shared standards.
• Use AI-assisted development tooling (Claude Code) with good judgment to increase your leverage in scoping, code review, implementation, and ramping quickly on unfamiliar systems.

Minimum Requirements

• 7+ years of commercial full-stack software development experience.
• 3+ years of production experience with React Native, including cross-platform (iOS + Android) apps shipped and maintained through app-store releases.
• Excellent engineering judgment and a solution-driven way of thinking.
• Strong proficiency with JavaScript / TypeScript.
• Strong proficiency with Node.js and Express.
• Production experience with React and NextJS.
• Production experience with both SQL and NoSQL data stores.
• Experience with real-time systems (WebSockets, event-driven architectures).
• Hands-on experience operating on AWS (ECS or EKS, Lambda, Cognito, SQS, CloudWatch).
• Comfort owning ambiguous problems and communicating technical decisions clearly in writing.

Nice to Have

• Experience with embedded / IoT systems (ex. MQTT, device fleets).
• Serverless and micro-services architecture.
• Infrastructure as code (Terraform, CloudFormation).
• Data-intensive or optimization/algorithmic work; big-data solutions and data warehousing.

• Medical Insurance, including plan options with 100% employer-paid premiums
• Dental Insurance
• Vision Insurance
• Meaningful Series B Equity
• 401(k) Plan
• Paid Time Off (PTO)
