Senior Software Engineer

Build the front door to our product

At Blueberry, the Acquire squad owns every moment from first impression to activated customer, the public website, onboarding, SSO, acquisition promotions, and the KYC journey that gets people live. It's the highest-stakes surface we have: what you ship here connects straight to conversion, revenue, and the first impression every customer forms of us.

We're after a Senior Engineer who's genuinely full-stack and takes ownership end-to-end, someone who cares as much about how a flow converts as whether the code is clean.

What you'll do

• Build and maintain features across the Acquire surface: website, onboarding, SSO, and acquisition-driven promotions
• Work across the stack, backend APIs and services in .NET, frontend product work in React / TypeScript
• Own features end-to-end, from shaping the solution through to production and what happens after it ships
• Contribute to architecture and technical direction in the squad, and hold the quality bar in code reviews
• Build multi-region, multi-lingual experiences (i18n, l10n, routing) and the infrastructure behind them
• Partner with the Product Owner, UX Designer and fellow engineers to ship experiences that convert and feel right
• Get ahead of performance, reliability and quality issues before they bite

What you'll bring

• Strong full-stack chops, solid .NET backend and confident with React / TypeScript on the frontend
• Solid relational database experience (code-first workflows a big plus)
• A track record of shipping quality software to real users in a product environment
• Frontend sensibility that goes past functional correctness, performance, accessibility, and SEO (technical SEO, structured data, Core Web Vitals) matter to you on a customer-acquisition surface
• Good engineering instincts, edge cases, failure modes and maintainability as a default
• Comfortable with fast-moving priorities and evolving context, and commercially curious about how what you build drives growth

Nice to have

• Onboarding, identity verification or KYC flow experience
• SSO protocols: OAuth 2.0, OIDC, SAML
• Dynamic rule engines / data-driven system behaviour
• Headless CMS and content-driven architectures
• Deep frontend performance work (Lighthouse, cross-device)
• Background in fintech, e-commerce or other high-conversion consumer products
