Post-Quantum Cryptography (PQC) Solutions Engineer, Consultant at 1bab367f-cd27-4c4c-b0fe-93f353748976:19000101_000001 – Washington | Jobyssey

Position Summary

Location: Remote / Hybrid (Washington, D.C. metro preferred)
Engagement Type: Part-Time Consultant with option to convert to Full-Time as demand grows
Travel: Occasional domestic travel may be required based on client needs

Square Peg Technologies is expanding a new services line focused on helping government and commercial organizations prepare for the post-quantum era. We are seeking a mid-level PQC Solutions Engineer to join us initially in a consulting capacity, with the opportunity to transition to a full-time role as the PQC practice scales and additional customers are onboarded.

This role is well suited for an engineer who enjoys hands-on technical work, thrives in early-stage service development, and wants to play a foundational role in building practical, real-world post-quantum cryptography capabilities. You will support tool evaluation, engineering prototyping, and client-facing technical delivery while helping shape reusable assets that enable the growth of Square Peg’s PQC offering.

This role supports early-stage assessments, technical validation, and pilot delivery efforts across multiple client engagements, and may require occasional travel to support client meetings, workshops, or on-site technical activities.

Key Responsibilities

Tool Evaluation and Testing

Evaluate open-source and commercial PQC libraries, cryptographic discovery tools, and key management solutions
Benchmark performance, assess compatibility, and document technical findings
Engineering and Integration
Develop reference implementations for integrating PQC algorithms such as Kyber and Dilithium into simulated enterprise environments
Build automation scripts and APIs to support cryptographic scanning and analysis workflows

Prototype and Lab Development

Create lab environments to simulate cryptographic migration and crypto-agile workflows
Test key management architectures and develop reusable engineering artifacts

Technical Documentation

Produce engineering design documents, tool comparison guides, integration checklists, and user documentation
Contribute to internal SOPs and delivery playbooks

Client Engagement Support

Support client pilots, demonstrations, and technical assessments
Deploy tools, collect cryptographic inventory data, analyze results, and contribute to client-facing deliverables

Internal Enablement

Package reusable scripts, tooling, and processes to support scaling the PQC service line
Participate in internal knowledge-sharing and engineering reviews

Required Qualifications

3–6 years of engineering experience in cybersecurity, secure systems development, or infrastructure security
Proficiency with at least one scripting or programming language such as Python, Bash, or PowerShell
Strong understanding of cryptographic protocols including TLS, SSH, and S/MIME, along with PKI and certificate lifecycle management
Experience integrating or working with cryptographic libraries such as OpenSSL, Bouncy Castle, or liboqs
Ability to design, document, and troubleshoot systems in complex environments

Preferred Qualifications

Familiarity with government security standards and guidance, including FIPS 140-3, NIST SP 800-175B, SP 800-131A, NSM-10, and OMB M-23-02
Hands-on experience with PQC tools such as Open Quantum Safe, SandboxAQ, or cloud-based KMS platforms with PQC extensions
Experience implementing encryption or key management in cloud environments such as AWS, Azure, or GCP
Familiarity with Zero Trust Architecture and modern identity frameworks
Experience with containerization or automation tools such as Docker, Ansible, or Terraform
Relevant cybersecurity certifications such as Security+, CISSP, or CCSP

Impact

In this role, you will help establish the engineering backbone of Square Peg’s PQC offering, delivering real technical value to early adopters, building reusable tools and reference implementations, and shaping how organizations begin their transition to post-quantum cryptography. Your work will directly influence how the practice scales, how clients adopt PQC technologies, and how the role may evolve into a full-time position as customer demand grows.

Why Join Square Peg Technologies

Consultant-first role with a clear path to full-time as the practice grows
Opportunity to help build a new national security and enterprise-focused capability
Work at the intersection of cryptography, quantum readiness, and cybersecurity
Mission-oriented clients and meaningful technical challenges
Flexible, remote-first environment with strong technical ownership

Additional Note

Compensation is extremely competitive and will be discussed based on experience, engagement scope, and availability.
