Principal Engineer, Investment and Proprietary Technologies

About Arki

Arki is an ambitious fintech company with bold ideas and even bigger goals. Our mission is simple: to empower people to take control of their financial futures with confidence, clarity, and the tools they truly deserve.

We're building something meaningful and fast. That means we value people who are curious, driven, adaptable, and ready to thrive in a little creative chaos. If you're excited about shaping the future of fintech while growing alongside a passionate team, we'd love to meet you.

Role Overview

We're looking for a senior technology leader to drive the design and evolution of our proprietary investment technology stack. This is a rare opportunity to operate at the intersection of deep engineering, data, and capital deployment, building systems that directly drive investment outcomes.

You will build and scale Arki's proprietary technology function from the ground up, with full ownership of the roadmap, architecture, and team structure. This includes hiring and developing a high-calibre engineering team.

Reporting directly to the CEO, you will work closely with investment leadership and play a central role in shaping the firm's investment engine.

This is not a standard engineering role — technology at Arki is a core driver of investment performance.

What You'll Do

• Own the architecture of Arki's proprietary investment platforms — from data ingestion to decision intelligence
• Design and build high-performance, scalable systems for market data processing, analytics, and internal workflows
• Partner closely with investment professionals to translate complex strategies into robust, production-grade technology
• Build and scale Arki's proprietary technology function, including hiring and developing a high-calibre engineering team
• Define the long-term technology roadmap aligned with investment strategy
• Make key decisions on architecture, infrastructure, and build vs buy
• Lead the development of data pipelines, modelling infrastructure, and scalable data systems
• Set and drive technical direction, standards, and best practices across the platform
• Identify and build opportunities for technology-driven investment edge in sourcing, diligence, and execution
• Mentor and elevate a high-calibre, lean engineering team

What We're Looking For

• 10–15+ years of experience in software engineering, with a track record of leading systems and teams in high-performance environments 
• Proven experience operating at Principal / Lead Engineer level or equivalent 
•  Experience in quant, trading, or investment platforms is a must
• Experience building and scaling engineering teams, ideally from 0→1 
• Strong background in system design and data-intensive applications 
• Experience building high-reliability systems 
• Deep understanding of data architecture, APIs, and scalable infrastructure 
• Strong proficiency in Python, with the ability to work across the broader application stack (e.g. TypeScript, Node.js) as needed
• Ability to operate end-to-end — from concept to production 
• Strong product intuition and ability to collaborate with non-technical stakeholders 

Bonus if you have:

• Exposure to financial markets, alternative data, or analytics tooling
• Background in AI/ML-driven systems

What You Will Gain

• Direct impact on real investment decisions and outcomes — your work drives more than just code
• Meaningful ownership in a high-growth fintech environment
• Exposure to the intersection of technology, data, and capital
• A fast-moving, intellectually stimulating environment with minimal bureaucracy
• The opportunity to help build a long-term competitive advantage for the firm
• A collaborative team where ambitious individuals learn, build, and win together
