Full-Stack Platform Engineer, ImpactOS
We are building a modern, data-driven platform that helps organizations design, manage, and optimize complex programs and operations.
This is a foundational engineering role where you will design and build a full-stack system from configurable workflows and management interfaces to real-time data experiences and scalable APIs.
You will work closely with product and data teams to ensure that complex data insights are accessible, intuitive, and actionable for end users.
As an early engineer, you will have significant ownership over architecture, system design, and user experience, and will play a key role in taking the product from concept to production. This is a full-time position reporting to the CTO.

Core Responsibilities
- Architect and build a full-stack platform using React + Next.js, Node.js / FastAPI, and PostgreSQL
- Develop configurable interfaces that allow users to define workflows, structures, and performance criteria across different use cases
- Build interactive dashboards to monitor performance, trends, and key operational metrics in near real-time
- Design and implement clean, scalable REST APIs to support frontend and data integrations
- Integrate backend services that expose analytical insights and system-generated signals to the UI
- Implement secure authentication and role-based access control using enterprise identity providers (e.g., Azure Active Directory)
- Integrate embedded analytics tools (e.g., Power BI or similar) for advanced reporting and visualization
- Build notification and alerting mechanisms to surface important system events and changes to users
- Design a flexible and extensible data model capable of supporting multiple use cases and evolving requirements

- Strong product mindset with the ability to translate loosely defined requirements into working systems
- Experience with Next.js (App Router, SSR, hybrid rendering)
- Familiarity with embedded analytics platforms (Power BI, Tableau, etc.)
- Experience with infrastructure-as-code (Terraform, Bicep, or similar)
- Exposure to real-time data patterns (WebSockets, event-driven systems, streaming pipelines)
- Experience building configurable platforms (workflow tools, form builders, or low-code systems)
- Familiarity with integrating external data or model-driven services into applications
- Experience working in regulated or security-conscious environments
- Comfort using modern AI-assisted development tools to accelerate delivery
