About The Position

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 based in the DC-metro area.

Requirements

5+ years of full-stack engineering experience with strong frontend and backend capabilities
Proficiency in TypeScript, React, and modern frontend architecture patterns
Experience building scalable backend systems using Node.js and/or Python (FastAPI)
Strong experience designing and consuming RESTful APIs
Solid experience with PostgreSQL, including schema design and performance optimization
Experience working with cloud platforms (Azure, AWS, or GCP)
Hands-on experience with Docker and container-based deployments
Experience implementing authentication and authorization (OAuth 2.0, RBAC, etc.)
Strong product mindset with the ability to translate loosely defined requirements into working systems

Nice To Haves

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
Familiarity with "Security First Design" and FedRAMP 20X requirements for cloud application services.

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
Develop and maintain containerized deployments using Docker and cloud-native services (Azure preferred)
Contribute to CI/CD pipelines and engineering best practices for reliability and scalability
Apply secure engineering practices including encryption, audit logging, and secrets management
Implement FedRAMP-aware infrastructure practices from day one: encryption at rest/transit, audit logging, secrets management via Azure Key Vault, infrastructure-as-code with Bicep or Terraform
