Role description
Junior & Senior Product Developer – Backend, Automation & Platform
Company: B2B Tech Group
Product: Company Compass (AI-generated sales intelligence dossiers)
Location: Remote (Global)
Type: Contract-to-hire
About the Role
We’re building the next generation of AI-powered sales intelligence. Company Compass is an AI workflow platform that automates the creation of high-value sales dossiers—helping businesses prospect smarter, faster, and with less manual effort. As our Product Developer, you’ll own the design, scaling, and delivery of the platform end-to-end:
• Architecting redundant backend systems so we never go down when a tool, API, or vendor fails.
• Running high-volume workflows with intelligent retries, monitoring, and batch processing.
• Leading the frontend delivery of client-facing web applications—from design to deployment.
• Integrating private LLMs to ensure accuracy, cost control, and reliability.
This is a founder-led, high-iteration environment—perfect for someone who can combine technical execution with product thinking.
Responsibilities
Reliability & Redundancy - Deliver fallback systems, circuit breakers, retry logic, and batch failover so the platform runs at capacity even during outages.
Workflow Optimization - Refactor into resilient orchestration with queues, idempotent jobs, and rate-limit-aware execution.
Data Integrity & Storage - Own the data layer in Airtable, Xano, or Supabase with enforced schema discipline, deduplication, and validation.
Frontend Development - Own the build and launch of performant web applications using Bubble, Softr, or Webflow, integrating backend data and optimizing for speed.
UI/UX - Wireframe, prototype, and iterate on user flows; deliver clean, intuitive interfaces aligned with modern standards.
Private LLM & Prompting - Deploy/manage private LLMs; maintain prompt libraries with version control and fallback models.
Monitoring & Observability - Deliver complete logging, metrics, and dashboards for workflows, LLM performance, and platform stability.
Qualifications
• Workflow Automation: n8n (queue mode), Make.com, or similar—proficient in error handling, queuing, orchestration.
• Backend & Data: Airtable, Xano, Supabase—data modeling, hygiene, and migration.
• Low-code Frontend: Bubble, Softr, Webflow—building and integrating full web applications.
• UI/UX Design: Wireframing, prototyping, usability iteration.
• Web App Delivery: Authentication, routing, and scalable architecture.
• Python: API integration, automation scripts, ETL, and data processing.
• LLM Integration: Private hosting, prompt engineering, orchestration patterns.
First 90 Days – What Success Looks Like
• Backend continues to run at full capacity despite outages in tools/vendors.
• Batch execution framework live with retry handling and monitoring.
• Launch of first iteration of PDF viewer + LLM chat or MVP client portal.
• Private LLM deployment live with fallback models and versioned prompts.
• UI is intuitive, responsive, and optimized for performance.
Who You Are
• Thrive in early-stage, high-iteration environments with minimal bureaucracy.
• Equally strong in backend orchestration and frontend platform delivery.
• Comfortable defining scope in parallel with building.
• Work in short feedback cycles, shipping value weekly.
• Bring a product mindset—always thinking about user impact and scalability.
