Sales Representative - US Federal

Arqit is a global pioneer in quantum-safe encryption: we provide a proven defence against both current cyber dangers and impending quantum threats. Our nearly 110 staff worldwide describe Arqit as succeeding in providing a positive and inclusive working environment, where staff feel that managers care about the success and well-being of their teams, and individuals feel valued as employees.

We have a new opportunity for a quota-carrying Sales Representative to own direct federal sales, with primary focus on the Department of War and secondary attention to civilian agencies as the pipeline matures. This is a closing role, not a business development or capture role — you'll work qualified opportunities through signed award, in close coordination with the Defense & National Security BD lead and Solution Architecture.

• Own the full sales cycle for named DoW (and select civilian) accounts — qualification through pricing, contracting, and close — applying a structured methodology (e.g., MEDDPICC, BANT) to keep the pipeline honest and forecasts defensible.


• Build and work relationships on both sides of the table: DoW program offices and contracting staff, and the prime/SI/reseller ecosystem that carries much of the federal cybersecurity business today.


• Run your territory like an operator — using CRM (Salesforce), AI-assisted tools, and disciplined note-taking to keep account intelligence, next steps, and forecast accuracy current rather than reconstructed after the fact.


• Work federal contract vehicles (GWAC, CIO-SP4, SEWP, agency IDIQs) within FAR/DFARS constraints, and lop in SI/prime partners where a teaming structure is the realistic path to award.


• Bring a point of view back to the team on what's working and what isn't — this is a small, early-stage commercial org, and account intelligence should flow both ways rather than sit with one rep.

What we're looking for

• Significant direct sales experience to the US Federal Government, with meaningful depth in Department of War / DoD accounts specifically.


• Proven success in selling cybersecurity, with a consistent track record of attaining or exceeding quota in complex, multi-stakeholder cycles.


• An existing network spanning both government stakeholders and the federal contractor base — the kind of relationships that get a first meeting scheduled without starting cold.


• Fluency with a structured sales qualification framework (MEDDPICC, BANT, or equivalent) and disciplined CRM hygiene — Salesforce experience strongly preferred.


• Comfort operating in a startup-like environment: figuring things out with limited playbook, adjusting approach based on what the market tells you, and pitching ideas rather than waiting for direction.


• Ability to work in the U.S. without restriction is essential.

Nice to have, but not essential:

• Genuine curiosity about emerging technology — this role sells at the leading edge of cryptography and network security, and candidates who track the space independently (not just react to it) tend to out-perform here.


• Experience selling through channel partners: co-sell motions, teaming agreements, and managing partner-sourced alongside direct-sourced pipeline.


• Direct exposure to post-quantum cryptography, key management, PKI, HSM, or zero trust categories.


• Familiarity with CMMC or NIST PQC standardization sufficient to speak credibly to compliance-driven buyers.
