About this role
G-P is a leading SaaS-based Global Employment Platform™ dedicated to breaking down barriers to global business. They are seeking a Senior Software Engineer to build the permanent Horizon 3 Discovery Engine, focusing on rapid prototyping and agile development to explore new business concepts and drive technical discovery.
Responsibilities:
- Extreme Product Ownership: Drive the technical discovery, design, API contracts, and rapid discovery of net-new business concepts
- Ship Weekly Behavioral Probes: Collaborate with your PM counterpart to build and launch weekly "sketchy V0s," fake-door landing pages, and concierge MVPs designed strictly for speed of validated learning
- Be an Eng Hacker: Prioritize speed over perfect architecture. Write clean enough code to test a hypothesis, but remain entirely willing to completely scrap and rewrite your stack when a project is killed or pivoted
- Build the Scrappy Engine: Wire up fast integrations, stitch together APIs, configure authentication, and implement usage tracking and product-led analytics on the fly
- Leverage Frontier Tech: Serve as the technical expert on the team, translating emerging primitives—like LLMs, multi-agent frameworks, decentralized protocols, and automation tools—into functional software prototypes
- Participate in Discovery: Don't just sit in an IDE. Join user interviews, review behavioral data with your PM, and use first-principles thinking to help decide whether to Persevere, Pivot, or Kill a concept at the end of each week
Requirements:
- Full-Stack Prototyping Chops: You can spin up frontend interfaces, spin down databases, and configure API integrations completely on your own. You are a generalist who values functional software over specialization
- Agentic AI Mastery: You use modern AI development accelerators (e.g., Cursor, Claude, GitHub Copilot) daily to build software at startup velocity
- 0-to-1 Hacking Experience: A proven track record of building apps, side projects, or early-stage software features from scratch
- Data Integration Agility: Experience working with disparate datasets, writing quick data transformation scripts, and setting up clean analytics events to track how users interact with prototypes
- Workflow Encoding Intuition: Ability to take real-world, friction-filled processes (like legal, compliance, or HR workflows) and rapidly translate them into elegant digital logic
- Extreme Ownership and Speed: You default to action, require zero supervision to deploy software, and possess a massive tolerance for ambiguity and changing requirements
- Early Startup Engineer: Experience working as a technical co-founder or an early engineering hire at an early-stage startup
- AI/LLM App Development: Hands-on experience building prototypes that leverage LLM orchestration libraries (e.g., LangChain, LlamaIndex, Vercel AI SDK) or custom agentic workflows
- Platform Deployment Agility: Proven ability to deploy, manage, and debug cloud-native prototypes autonomously using AWS services (e.g., ECS/Fargate, S3, Lambda or Bedrock)
- Integration Experience: Practical knowledge of rapidly integrating with diverse enterprise APIs (e.g., HRIS, fintech, identity management, CLMs) with a particular focus on fast auth and data mapping
