Senior Software Engineer at Aries Global in London, England, GB

Aries Global

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

• Build and ship real product features that meaningfully improve the user experience and drive business impact.
• Collaborate with senior engineers, product managers, and designers to turn ideas into polished, scalable solutions.
• Dive into modern technologies and development practices, learning rapidly while contributing to production-quality work.
• Debug, test, and optimise systems to enhance performance, stability, and maintainability.
• Participate in code reviews and team rituals to strengthen engineering excellence and learn best practices.
• Explore new tools and frameworks to help the team innovate and improve developer productivity.

What We’re Looking For

• Analytical Foundations. A strong analytical foundation built through experience in start-ups, investment banking, PE/VC, strategy, or management consulting - environments that demand rigorous thinking, structured problem-solving, and rapid synthesis of information.
• Action Bias. You thrive in ambiguity, form clear mental models quickly, take ownership instinctively, and enjoy diving deep into unfamiliar software categories. You operate with autonomy, intensity, and a strong internal drive.
• Culture & Velocity Fit. You’re energized by environments defined by ambition, precision, and ownership and a high standard of integrity and responsibility.
• Communication & Reasoning Clarity: You communicate in a structured, concise, and compelling way - verbally and in writing. You’re highly organized, detail-oriented, and able to manage multiple workstreams without sacrificing quality or momentum.

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.
