Are you a software engineer who wants to understand how systems work beneath the application layer? Do you enjoy analyzing source code, tracing network communications, understanding database internals, and solving complex engineering challenges?

PEMCCO is seeking a Systems Software Engineer with expertise in systems programming and database engineering to support mission-focused government programs. This role goes beyond traditional application development and database administration. You will work directly with database engines, communication protocols, operating system interfaces, cloud platforms, and identity services to develop, integrate, and enhance secure software solutions.

This position is ideal for engineers with experience in systems programming, database engineering, software integration, cloud technologies, and secure application development who enjoy understanding how complex systems behave and interact across an integrated technology stack.

About PEMCCO

PEMCCO delivers engineering, technology, cybersecurity, and mission support services to federal government customers. Our teams develop and sustain secure, innovative solutions that support critical government operations and mission success.

Job Overview

PEMCCO is seeking an experienced Systems Software Engineer to support the development, modernization, and integration of secure software systems.

In this role, you will analyze source code, trace data flows and network communications, understand database engine processing, and implement software changes that support evolving mission requirements. You will work across relational databases, graph databases, identity platforms, cloud environments, and supporting infrastructure while collaborating with cybersecurity, infrastructure, and mission stakeholders.

This is a highly technical position for engineers who can reason through complex software behavior, troubleshoot issues across multiple layers of a technology stack, and confidently work within unfamiliar codebases and protocols.

What You'll Do

Develop, maintain, test, and deploy secure, scalable applications and services using C, C++, Rust, Go, Java, Python, or Node.js.
Apply systems programming principles, particularly in C, C++, and Rust, to develop high-performance, reliable software components.
Develop software supporting process creation, monitoring, control, and inter-process communication.
Build concurrent and multithreaded applications utilizing synchronization, signal handling, memory management, and resource-control techniques.
Design, implement, and troubleshoot networked applications using sockets, client-server architectures, and applicable network protocols.
Analyze database engine source code, communication protocols, request and response formats, serialization methods, and packet layouts.
Trace requests through database engine code to identify processing logic, integration points, and operational impacts.
Develop relational data-storage solutions using SQL, including data modeling, query development, performance tuning, and access control.
Develop and integrate graph database solutions supporting relationship-based data modeling, analysis, and retrieval.
Work across relational databases, graph databases, object storage, and search/indexing technologies including PostgreSQL, Redis, RxDB, Neo4j, Amazon S3, and Elasticsearch.
Refactor and modernize existing services, including transitioning functionality from Python to other implementation languages where appropriate.
Develop and maintain Infrastructure as Code (IaC) solutions to provision, configure, and manage environments through repeatable, version-controlled workflows.
Deploy, monitor, and troubleshoot cloud-hosted software, including dependencies on compute, storage, networking, identity, and security services.
Integrate applications with identity providers to support authentication, authorization, federation, single sign-on, and identity-aware access control.
Implement OpenID Connect (OIDC) integrations, including token validation, claims processing, client registration, redirect flows, session management, and secure API access.
Incorporate Zero Trust Architecture principles into software designs and implementations.
Collaborate with cybersecurity, infrastructure, data, and mission stakeholders to integrate security controls, cryptographic protections, logging, monitoring, and auditability throughout the software development lifecycle.
Produce and maintain software designs, interface specifications, deployment procedures, configuration baselines, security implementation details, and operational support materials.

What You Bring

Required Qualifications

Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Information Technology, Information Systems, Mathematics, or a related field.
10+ years of software engineering experience.
Active TS/SCI clearance with the ability to obtain and maintain a CI Polygraph.
Experience supporting Intelligence Community or other federal government programs.
Strong software development experience using one or more modern programming languages such as C, C++, Rust, Go, Java, or Python.
Experience with systems programming concepts, including process management, concurrency, multithreading, inter-process communication, and memory management.
Experience developing or troubleshooting networked applications and client-server systems.
Experience with relational databases, SQL, and database design concepts.
Ability to analyze and modify complex codebases and troubleshoot problems across multiple layers of a system.
Experience with Agile software development methodologies.
Strong communication, collaboration, and technical documentation skills.
Security+ (or higher) certification.

Preferred Experience

Experience with database internals or database-engine development.
Experience with PostgreSQL, Neo4j, Redis, Elasticsearch, or similar technologies.
Experience with cloud technologies such as AWS or AWS GovCloud.
Experience with Kubernetes, OpenShift, Terraform, or Ansible.
Experience implementing OIDC, SSO, identity management, or Zero Trust architectures.
Experience supporting classified or mission-critical environments.
Experience with protocol analysis, packet captures, serialization technologies, or low-level communications.
Experience with cryptographic services, PKI, HSMs, or PKCS #11 integrations.
Advanced degree in a related technical field.
