OUR MISSION Bounti is building the AI-native infrastructure layer for frontline teams — spanning training, audits, and autonomous operations. We partner with multi-location operators in frontline-industries such as hospitality. We’re hiring a Senior Product Engineer to join our founding product team in Berlin. This is a hands-on role for someone who loves ownership, sweats UX details, and ships fast, end to end delivering value for customers. WHAT YOU'LL DO * Build Product End-to-End: Own features from concept → implementation → release → iteration (frontend + backend). * Ship Fast, Learn Faster: Deliver quickly, validate with customers, and iterate. Biggest risk is building the wrong thing — not imperfect code. * Customer-Driven Engineering: Talk to users and customers directly, understand the workflow pain, and turn feedback into product improvements. * Design-First Execution: Partner closely with Ziar (Designer & Co-Founder) to create experiences that feel premium and intuitive. * Raise the Engineering Bar: Improve patterns, code quality, DX, testing, and observability without slowing down shipping. * Work Like a Founder: Prioritize ruthlessly, own outcomes, and help shape what “great product engineering” looks like at Bounti. YOUR PROFILE * You have a strong product sense — you care about UX, clarity, and the tiny details that make software feel “right”. * You’re strong on the backend (you’ve built and scaled real production systems) — and you’re not afraid to go deep when needed. * You’re pragmatic and impact-driven: you know when to polish and when to ship to learn. * You write clean, understandable, maintainable code — and you communicate context early and often. * You enjoy getting close to the problem: talking to customers, understanding real-world constraints, building solutions that stick. * Experience with our stack is a plus: TypeScript, React, Next.js, Node.js, Postgres, Prisma. Bonus points if you have: * Built AI product features (LLMs, agents, workflows, evaluation, etc.) * Mobile product experience (Flutter, React Native or similar) * ML experience You’ll work extremely closely with: * Çağatay (Senior Product Engineer) * Emanuele (Senior Product Engineer) * Yannick (Software Engineer) * Ziar (Designer & Co-Founder) …and often with Deniz (Co-Founder) who brings constant customer perspective. This is a small, high-trust team. Low ego, high standards, lots of shipping. WHY US? * Founding-team level ownership: You’re not “implementing tickets”, you’re shaping the product building high-value bets and stay close to customers. * Real societal impact: We’re building for the 80% of the workforce that doesn’t sit at a desk — and software has ignored them for too long. * Design-focused culture: Craft matters here. You’ll build software you’re proud to show. * Customer obsession: We build what serves operators and frontline teams — not engineering for engineering’s sake. * Backed by exceptional investors: We’re backed by top-tier VCs and investors like the founders of Framer and Indeed. * Remote or In-Office in Berlin: You can work remotely (CET/CEST ±1 hour only), or in our beautiful Berlin office, top equipment, 30 days holiday, impact from day 0. We embrace diversity and hire people based on their ability to perform a job. People of any race, gender, gender expression, sexual orientation, religion, age, disability, political opinion, or marital status are welcome at Bounti.

JOB DESCRIPTION We are building a modern analytics and Business Intelligence solution for customers in the temp-staffing industry, integrating operational data from multiple ERP systems across countries into reliable, customer-facing insights, analytical workflows, and reusable data products. This is not a traditional data analyst or classic BI developer role. We are looking for a product-minded fullstack engineer with a strong data focus: someone who can move from messy ERP data and product-defined KPIs to validated datasets, pipelines, APIs, internal tools, and dashboards where needed. AI and LLM tooling are central to how we work. We expect someone who uses AI-native workflows to explore faster, build in parallel, validate assumptions, and ship high-quality production solutions. What We’re Looking For We are looking for a fullstack engineer with a strong data focus. You should turn ambiguous problems into working software, use AI as a default development workflow, care about correctness and maintainability, understand data edge cases, choose simple robust solutions, own the outcome from exploration to production, and move quickly while verifying aggressively. YOUR TASKS * Fullstack Product Engineering: Build backend services, APIs, internal tools, lightweight UI/admin screens, automation, job runners, integrations, and customer-specific configuration around the data * Data Pipeline & Modeling: Ingest, validate, transform, and document ERP, API, SQL, file, and cloud data; map product-defined KPIs to available sources and identify gaps or inconsistencies * Curated Data Products: Create validated, analysis-ready datasets with consistent schemas, reproducible transformations, and clear naming for reporting, APIs, product features, and customer-facing analytics * Cloud & Production Ownership: Deploy and operate reliable cloud solutions, preferably AWS, owning monitoring, alerts, failure handling, performance, cost, and operational reliability YOUR PROFILE AI-Native Development * Hands-on with Claude Code, Codex, and agent-based workflows; GitHub Copilot-style autocomplete alone is not enough * Familiar with worktrees, subagents, MCP, structured prompts, harness engineering, parallelization, and validating AI-generated code and analysis to production quality Software Engineering * Strong fullstack/backend experience, ideally with Python and/or TypeScript * Able to build production-grade services, APIs, scripts, tools, automation, and clean interfaces; comfortable with version control, review, debugging, testing, and existing systems Data Engineering & Analytics * Strong SQL, data modeling, analytical schemas, transformations, and downstream data use * Able to translate product-defined KPIs into datasets and metrics, and validate messy operational data, edge cases, system limitations, and customer-specific differences Cloud & Infrastructure * Hands-on with AWS or similar cloud environments, including storage, databases, queues, containers, serverless/scheduled processing, SDKs, and APIs * Understands deployment, secrets, networking, permissions, runtime configuration, scalability, performance, cost, and operational trade-offs Good Fit You may be a good fit if you are a fullstack/backend engineer with strong data or analytics experience, a Python/TypeScript engineer who enjoys data products and automation, an analytics/data engineer with real software engineering depth, a technical founder/builder profile, or an AI-native engineer using LLMs and agents daily for production work. Not a Good Fit This role is probably not the right fit if you are mainly a dashboard-only BI analyst, classic report builder, pure data warehouse engineer waiting for predefined tickets, notebook-only analyst without production engineering experience, engineer with no interest in data modeling, someone who avoids ambiguity, or someone who does not actively use and rigorously validate AI-generated output. YOUR BENEFITS * Collaboration in an empathetic, appreciative team with room to contribute ideas and take ownershipIndividual development opportunities, structured onboarding, and interdisciplinary collaboration * Flexible working models including hybrid work, home office, and mobile working * A modern tech environment and agile ways of working * Additional benefits such as pension plans, health offers, and employee discounts I LOOK FORWARD TO RECEIVING YOUR APPLICATION Svenja Krüßel D-49835 Wietmarschen-Lohne Tel.: 0170-7888740 E-Mail: career@zvoove.com
