Job description

Role Overview

At Aries Global, we’re driven by a singular ambition - to build one of the world’s truly exceptional software groups. A high-performing culture where we’re able to deliver transformative value to our group, and a place where every team member can grow, thrive, and achieve their full potential. A company that operates with unmatched precision, creativity, and impact. That creates enduring value while upholding the highest standards of integrity and responsibility.

Our mission is simple: we don’t just acquire companies - we build enduring, AI-native software platforms. We partner with founders who have built great products and help them unlock their next chapter through our AI-native operating system, centralised GTM engine, and world-class execution capabilities.

We bring together exceptional operators, product builders, and leaders - people who insist on the highest standards and excel in a culture of fast pace, focused execution, and deep ownership. In return, you’ll experience extraordinary growth, meaningful impact from day one, and a career trajectory far steeper than you thought possible.

Some Of Your Responsibilities

• Work hands-on across strategy, product, hiring, GTM, and group operations, acting as a direct extension of the Founders & Chief of Staff.

• Break down high-level strategic objectives into actionable plans and drive execution across commercial, marketing, finance, operations, and product teams.

• Lead 0-to-1 initiatives and critical cross-functional projects end-to-end: opportunity sizing, scoping, execution, stakeholder management, and delivery at speed.

• Drive operational optimisation by identifying inefficiencies, implementing process improvements, and using data to measure impact.

• Build leverage for leadership by preparing decision-ready materials for founders, investors, and board discussions.

What We’re Looking For

Exceptional Operator
Experience in a fast-paced environment such as a startup, scale-up, investment firm, consulting role, or operating team. You’ve worked close to decision-makers and are comfortable across strategy, operations, and execution.

Execution Excellence
Highly organised, detail-driven, and dependable under pressure. You can juggle multiple priorities, stakeholders, and deadlines without losing momentum or quality.

Ownership Mentality
You take responsibility end-to-end, anticipate what’s needed next, and operate with minimal supervision. You care deeply about outcomes, follow-through, and building things that last.

Strong Communication & Judgment
Clear, structured communicator – written and verbal – with strong judgment around prioritisation, trade-offs, and operating in high-trust, high-stakes environments.

Process & Systems Mindset
You naturally think in plans, workflows, and operating rhythms, and are motivated to improve how work gets done through better structure, tooling, data, and automation.

Ambition & Growth Orientation
You set a high bar for yourself, want to grow fast, and are excited to operate in a demanding, founder-led environment with exposure far beyond a traditional role.

Opportunity to Convert
This role is designed as a high-impact entry point, with a clear opportunity to convert into a long-term role based on performance, ownership, and impact.

Why Join Aries

• Unmatched talent density - be amongst and learn from the brightest.

• High-trust, high-autonomy environment with real ownership - exposure you won’t get anywhere else.

• A company with global reach, meaningful work, and potential for long-term growth.

Our Process

Joining Aries Global means stepping into a culture that values excellence, curiosity, and potential above all else. Our selection process reflects that.

If you excel at our initial screening, you move forward to interviews that dive deeper into your ambitions, mindset, and how you can shape growth with us. You’ll take on a few challenges designed to see how you think, learn, and adapt under pressure. They’re demanding by design - because the work we do is, too.

We set the bar high and only make offers when we’re confident it’s an extraordinary fit - for both you and Aries Global.

And if you’re hesitating because you don’t tick every box - don’t. Talent, drive, and the will to grow matter most here. If you’re inspired by our mission and believe you can make an impact, we want to meet you.

Aries Global is proud to be an equal opportunity employer. We celebrate diversity, foster inclusion, and ensure every candidate has equitable access to succeed. If you need accommodations during the process, simply let us know, we’ll make it happen.
