Lead Software Engineer

We are looking for a properly T-shaped senior or lead developer: someone who can design and ship a website, a mobile app, an automation pipeline or a piece of cloud infrastructure with equal confidence, and who enjoys moving between all four in the same week. AWS is our core platform, and backend experience on GCP matters too. This is not a heads down coding role. You will design solutions, write them down properly, build them, deploy them, and support the people around you. You will work directly with both founders as the most senior hands on technologist in the business, and the role is deliberately built with headroom: we want someone hungry to stretch into technical leadership, with a genuine path to Director level.

What you will build

• A multi market digital platform for a global food and beverage brand, rolling out a headless CMS, ecommerce and loyalty across roughly thirty markets.
• Mobile apps that matter, from a voice led motion tracking sports product to apps in health and social care, built in Flutter and React Native and shipped through the app stores.
• AI that actually works: readiness audits, agentic automations and thin, well aimed AI tools for charities, foundations and enterprise clients, never hype for its own sake.
• Portals and integrations for charities moving millions of pounds in grants to the people who need them most.
• Our own operating platform, infrastructure and tools. A connected system of ClickUp, Make.com and AI agents, AWS, github and more.

What you will own

• End to end technical delivery on your workstreams, covering solution design, architecture, build, deployment, documentation and handover, done properly every time.
• The written thinking behind the build: solution designs and tech specs that a client can sign off and a teammate can pick up cold, because if it only lives in your head it is not done.
• Our AWS estate (Lightsail, EC2, IAM Identity Centre, CloudWatch) connected to our microsoft tools, and our infrastructure standards, with GCPwherever the work calls for it.
• Your own board hygiene: you write your tickets, estimate them honestly, and lead by example so the standard holds for everyone.
• Support for the rest of the team through code review, pairing, mentoring and unblocking, so the whole studio ships faster because you are in it.
• Pace with honesty: you escalate early, communicate clearly and summarise well, because in a team this size silence is the only unforgivable failure.

• Senior or lead level experience with a track record of shipping across web, mobile, automation and infrastructure, not just one lane.
• Strong AWS, and fluency across modern web stacks (TypeScript, React or Astro style), mobile (Flutter or React Native), APIs and integration work. AI tools and automation platforms.
• Proven solution design and documentation ability, with evidence you can architect and write, not just build.
• Time in both startups and corporates, so you bring pace and structure in the same person.
• Client facing credibility: you have sat with clients, understood their world and carried technical decisions with them, and even a year or two client side counts.
• A self-starting operating style: you work through blockers, unblock yourself, and escalate only the things that genuinely need a founder.

It helps if you have:

• Headless CMS experience (Storyblok especially), Salesforce ecosystem exposure, or ecommerce and loyalty builds behind you.
• Real LLM and agentic AI build experience that goes beyond prompting.
• App store release pipelines (TestFlight, App Store Connect), Stripe, and Sentry in your recent history.
• Depth in Make.com, Zapier or similar automation platforms.

Pulled from the full job description

• Flexitime
• Employee mentoring programme
• Company pension
• Work from home, * You are entrepreneurial and dynamic: give you an outcome, a wiki and a Slack channel and you will find the path with very little guidance.
• You are flexible in how you work because a growing studio demands it, and you care more about solid outcomes than tidy job boundaries.
• You are honest, direct and kind, and you would rather flag a problem on Tuesday than confess it on Friday.
• You want to help build a company, not just close tickets, and you want a share of the journey and the rewards that come with it.

Where this goes

This role is designed to grow. As we scale we will need strong Directors, and we would far rather grow one than buy one. Show us the leadership and the pathway is real, with coaching and a widening remit to match.

Impact

Every project we ship carries a defined social impact outcome, tracked with the same rigour as its financial result. Accessibility to WCAG is our minimum standard, humans stay in the loop by design in every AI build, and we make responsible, low harm technology choices the default.Terms and reward

• Employer: Rascal Ventures Ltd
• Full time, forty hours Monday to Friday, with fexible remote hours that work both ways.
• Salary: 40,000-60,000, reviewed annually.
• Pension, twenty two days holiday plus the eight bank and public holidays in England and Wales, and real support for professional development.

Rascal Ventures is a B Corp technology studio on a mission to put the joy and humanity back into building technology. We are a small, senior team founded in 2021, scaling with intent. We partner with forward thinking organisations to drive real change through technology, people and culture, and we work by a simple belief: people and process come before technology, and genuine change beats performative adoption every time. Its a people first, AI last approach that works. Being B Corp aligned means every role here carries real accountability for social and environmental outcomes alongside commercial ones. We only take on work we believe in, and a lot of what we build genuinely helps people.
