Software Development Engineer

Help build the software infrastructure that makes complex data systems more visible, resilient, and responsive. Join NS2 Mission as a Software Development Engineer in Herndon, VA , where you'll design and develop distributed, event-driven solutions that support reliable data processing and real-time operational awareness.

You'll work across data pipelines and distributed services to create modular, scalable software capable of adapting to new data formats and mission requirements. Using technologies such as Python, Kafka, Grafana, and the ELK stack, you'll help strengthen observability, automate alerting, and build fault-tolerant systems that give engineering teams greater insight into how data and applications perform.

Key Responsibilities

• Design and develop event-driven software architectures that support distributed data processing and system integration.
• Build modular software components that can adapt to new data formats, domains, and evolving mission requirements.
• Develop Python-based applications using asynchronous and concurrent programming techniques.
• Implement distributed messaging and event processing solutions using Kafka.
• Design systems with a focus on fault tolerance, reliability, scalability, and maintainability.
• Develop observability capabilities that provide visibility into application, pipeline, and system events.
• Create dashboards, monitoring solutions, and operational views using Grafana and the ELK stack.
• Implement real-time alerting and event tracking to support proactive identification and response to system issues.
• Apply appropriate access control and security practices across event-driven and distributed environments.
• Support JSON-based data interchange and integration across services and data pipelines.
• Collaborate with software engineers, data engineers, and mission stakeholders to troubleshoot issues and improve platform performance.
• Contribute to technical documentation, design reviews, and software engineering best practices.

Required Qualifications

• Experience developing modular, scalable software components and services.
• Working knowledge of JSON and service-to-service data interchange.
• Understanding of fault-tolerant and highly available system design.
• Familiarity with software observability concepts, including logging, monitoring, metrics, and alerting.
• Experience working in Agile software development environments.
• Strong analytical and troubleshooting skills with the ability to solve complex technical challenges.

Preferred Qualifications

• Experience implementing access control within event-driven or distributed architectures.
• Strong background in modular software design for data pipelines and distributed processing systems.
• Experience with Grafana, ELK/Elastic Stack, or comparable observability platforms.
• Knowledge of real-time alerting, event tracking, and operational record-keeping solutions.
