Core Software Engineer in England

At Aries Global, we are driven by a singular ambition - to build one of the world's truly exceptional software groups. A high-performing culture where we can deliver transformative value to our group, and a place where every team member can demonstrate autonomous impact in a highly collaborative environment. 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.

The Role

You will build production systems that matter. Not tickets. Not side projects. Core product. We are hiring at all levels: from early-career engineers to seasoned technical leaders. What matters is how you think, build, and ship. You'll take end-to-end ownership of features from architecture design to measurable impact — shipping code that directly moves revenue, retention, or product velocity. You'll design clean abstractions in ambiguous environments, evolve systems into scalable AI-native platforms, and make strong trade-offs between velocity and durability.

If you're backend-leaning: You'll use Ruby, Python, TypeScript to build and improve a high-performance platform — designing APIs, data models, and integrations that scale. If you're frontend-leaning: You'll use React and TypeScript to build smooth user experiences that handle real-time data. Either way, you'll collaborate directly with product and commercial teams to shape what gets built, not just how. We care about outcomes, not activity.

What We're Looking For

• You've built and shipped real systems.
• You understand data modelling, API design, system trade-offs, testing, and reliability.
• You know how to move fast without creating chaos.
• You're strong in at least one modern stack — full-stack ability is a big plus.
• You think fast and communicate clearly.
• You form mental models quickly, break down ambiguous problems, prioritise high-leverage work, and explain your reasoning concisely.
• You may come from a startup, a top-tier engineering team, or an analytically rigorous environment.
• You own the outcome. You don't wait to be told what to do. You don't hide behind ambiguity. You care about the result — and you act on it.
• You're AI-native. You're actively exploring LLM workflows, AI tooling, automation, or developer productivity improvements. You see AI as a force multiplier, not a buzzword.

Culture

High standards. Low ego. Direct feedback. Fast execution. Real accountability. We value people who care deeply about the craft and the outcome.

• Real ownership from day one.
• Exposure to multiple software platforms and business models.
• A growth curve far steeper than you thought possible.
• We set a high bar. We hire carefully. We invest heavily in those who clear it.
