Senior Backend Engineer (Node / NestJS)

Direct message the job poster from White Sand SRL

Founder, CEO @ White Sand | Creator of Data Dive

Superbaking is an AI-native startup founded by engineers who have actually shipped complex products before. Our CEO has a long software career — from coding to leading hundreds — and together with our current tech lead, created DataDive.tools , one of the most widely used SaaS platforms for Amazon sellers.

We’re now applying that same product discipline to a mobile app that blends AI reasoning, real-world sensors, and structured UX into something genuinely new. The first use case is our own best seller baking brand, but the underlying framework can power a new generation of AI-driven mobile apps for physical-product companies . This is the ground floor of something technically challenging, fast-moving, and real .

Why This Role Matters

You’ll own critical backend modules for our chat-first assistant — systems that remember users, manage structured memory, and enforce safety through schemas and consent. You’ll define reliability, performance, and developer experience , keeping the AI layer robust and future-proof.

Must-Haves

• 5+ years building production Node / TypeScript services end-to-end
• Strong systems thinking : domain modeling, event lifecycles, idempotency, migrations
• Code-quality leadership : SOLID, modular boundaries, DI, repository patterns, strict types
• Testing strategy across unit / integration / e2e , with CI discipline
• Pragmatic observability (logs, tracing, metrics); debug without guesswork
• Mentorship ability — elevate PRs, explain trade-offs, guide structure

What You’ll Do

How We Work

We’re a highly technical team that values clarity, autonomy, and craftsmanship. We operate with radical transparency and live by our core values : personal responsibility, direct honesty, bidirectional loyalty, fairness, ambition, continuous improvement, an action-oriented mindset, and data-driven rational thinking.

We move fast — not chaotic — with strong respect for design, testing, and clean architecture. Startup energy meets engineering discipline : perfect for those who love solving hard problems without bureaucracy.

We communicate in English , primarily via Slack and Notion. Meetings are short and purposeful; most decisions are documented asynchronously. Code reviews are thoughtful and technical — if you can explain why your code exists, not just what it does, you’ll thrive here.

You’ll work directly with leaders who built DataDive.tools , gaining exposure to real product strategy and large-scale AI integration. We’re already developing a second major product — an E-commerce Performance Analytics platform — so there’s room to expand into new domains and technologies.

We use AI everywhere — from generating type-safe scaffolding to analyzing prompts — but never on autopilot. At Superbaking, AI is a power tool , not a substitute for thinking. We expect engineers to understand, challenge, and refine what the model suggests. If you want to learn faster without losing ownership of your code and decisions, you’ll fit right in.

Remuneration

About Us

We’re building an AI-native ecosystem that redefines how physical-product brands interact with users — starting with baking, expanding to analytics, and powered by a team that loves to code. If you think in systems, write with care, and want to grow faster than most environments allow, you’ll fit right in.
