Software Engineer

Software Engineer Office Location: Temple, London - Hybrid (3 days/week in office) Experience Level: +3 years commercial software engineering experience About Investa Investa is building the UK’s first zero-commission Options and Stocks trading platform. Legacy platforms typically feature high fees and complex interfaces that cut out the majority of retail investors. We are building a streamlined alternative to fix that.   So far, we have raised £3.5 million in funding, secured direct regulatory approval from the FCA, and picked up two major awards in 2026: Best Options Trading App (Good Money Guide) and Best App for Options Trading (ADVFN). Having launched on iOS - reaching 4,000+ total sign-ups - we have now just launched on Android, doubling our addressable market as we scale toward targets of 10,000 users, 100,000, and expand across Europe.   Key Platform Traction: 8,000+ trades processed 2,500+ early supporters rewarded for their loyalty 1,000+ shareholders backing our vision 150+ 5-star reviews Our goal is straightforward: Think Options, Think Investa.   We are a lean, agile team where every employee directly shapes the business. We don't have a corporate way of working. Instead, we look for people who want high autonomy, care about making a visible impact, and align with our core values of being Collaborative, Curious, and Creative. The Role The Investa app was installed over 1,000 times within the first 24 hours of our priority access launch, and we’re now looking for a driven Software Engineer to join our founding engineering team as we scale. Having passed the junior stage of your career, you bring over 3 years of commercial experience writing clean code and shipping features independently. In this role, you will take true end-to-end ownership of core platform features, work across our stack, and step outside your comfort zone to level up your technical depth alongside our talented engineering team of 4. If you’re passionate about building best-in-class products to tackle complex financial challenges and you excel in a fast-paced, collaborative environment, we want to hear from you. What the Role Involves Founding Team Ownership: Designing, building, and maintaining robust, scalable services by joining our founding team of 4 engineers. Working directly with the founders without corporate red tape, , you won’t just pull tickets from a backlog - you will actually own your work end-to-end, see your code ship, and see its immediate impact on users. Building the Engineering Culture: Joining our founding engineering team means you are actively building our engineering culture, not just stepping into one. You will have a direct voice in shaping how we collaborate day-to-day, how we learn from each other, and how we preserve a friendly, agile, and tight-knit environment as we grow. Full-Stack Versatility & Growth: Hands-on Building: Writing high-quality, secure code for our FCA-regulated platform. You’ll navigate our stack to ship features that delight users. Driven by our fast-paced environment, you will have the opportunity to step outside your comfort zone and get hands-on with the wider technical stack, levelling up your skills significantly faster than in a traditional, highly specialised role. System Design & Architectural Contribution: Partnering directly with the engineering team to tackle complex systems design and actively shape our evolving architecture. Your technical perspective will give you a strong voice in our high-level design choices. You will have true design ownership over the specific services and components you build, ensuring they remain robust, secure, and performant as we scale. Technical Excellence: Maintaining a high bar for code quality, testing, and documentation. You’ll participate in (and contribute to) meaningful code reviews. System Integrity: Monitoring and improving system reliability, ensuring our trading platform is always "always-on
