INTRODUCTION
The Public Sector software engineers (SWEs) create the core product building blocks forward-deployed teams use to develop agentic capabilities that function across multiple domains. SWEs responsibilities include building the systems required to ingest and process federal datasets to support real-time decision-making in contested environments. We develop novel agentic enabling capabilities that includes:
* Create multi-layered guardrails around agents
* Optimize data retrieval for agents
* Orchestrate fleets of asynchronous agents
* Automatically alerts users to deviations in data
* Illustrating how an agent reached a decision
ROLE AND RESPONSIBILITIES
As a Staff Software Engineer, you will orchestrate the implementation of vertical features and horizontal capabilities to include mentoring other engineers on defining requirements with stakeholders and communication tradeoffs of technical implementations on feature and capabilities until they are accepted by the stakeholders.
You will:
* Orchestrate feature implementation across the Federal engineering team to ensure architectural consistency.
* Define technical strategy for agentic guardrails, explainability, and fleet orchestration.
* Ensure system reliability and performance across multiple security classifications and network types.
* Mentor engineers in the process of defining requirements with stakeholders and gathering acceptance.
* Communicate high-level technical trade-offs and implementation strategies to senior government stakeholders and Scale C-Suite members.

* Data Engineering: Knowledge of ETL (Extract, Transform, Load) processes and experience in building data pipelines to integrate and process diverse data sources. Understanding of data modeling, data warehousing, and data governance principles.
* AI Application Integration: Familiarity with integrating Large Language Models (LLMs) and building agentic workflows. Understanding of prompt engineering, retrieval-augmented generation (RAG), and agent orchestration is beneficial.
* Problem Solving: Strong analytical and problem-solving skills to understand complex challenges and devise effective solutions. Ability to think critically, identify root causes, and propose innovative approaches to overcome technical obstacles.
* Collaboration and Communication: Excellent interpersonal and communication skills to effectively collaborate with cross-functional teams, stakeholders, and customers. Ability to clearly articulate technical concepts to non-technical audiences and foster a collaborative work environment.
