Founding team

Senior technical co-founder / CTO or founding engineer.

GSJ is looking for a senior technical builder to help lead the next stage of an already established platform foundation.

The role

What this role is

This is a high-ownership, early-stage role for someone who can understand what already exists, strengthen it, scale it and help shape the next stage without restarting the foundation.

What we are looking for

Must-have

  • Senior hands-on software engineering experience
  • Strong backend and systems thinking
  • Secure SaaS / security-minded development
  • Identity and access management concepts
  • API and third-party integrations
  • Ability to understand and extend an existing codebase
  • Strong technical judgement and ownership
  • Clear, constructive communication and high reliability

Strong advantage

  • Cloud / DevOps / CI-CD
  • Data-intensive systems
  • Identity, verification, trust, compliance or regulated systems
  • AI-enabled product experience at a high level
  • GovTech, RegTech, security, defence or critical-infrastructure experience
  • Previous startup, founding engineer or CTO experience

Mindset

  • Visionary and willing to challenge conventional thinking
  • Professionally boundary-pushing, but disciplined
  • Loyal, constructive, positive and motivating
  • Curious, resilient and comfortable with ambiguity
  • Able to disagree without becoming destructive
  • Respects the existing foundation while improving what genuinely needs improvement
Established foundation

The core direction and foundation are already established. The role is to strengthen, scale and extend what has been built — not to restart it.

Compensation & transparency

GSJ is currently at an early stage and is not yet in a position to offer a conventional full-time salary for this founding role.

For the right co-founder-level candidate, the structure is expected to include meaningful equity aligned with long-term responsibility, contribution and commitment.

Exact role, commitment, equity structure and transition to paid compensation will be discussed openly before either side makes a commitment.
