## Job description

## About fonio

We grew from $1M to $10M ARR in under 12 months and now serve 10,000+ customers. Fonio is Europe’s market leader for AI phone agents for SMBs. Now we’re expanding globally and into new products. We move fast, take ownership, give direct feedback, and avoid politics and unnecessary meetings. Join one of Europe’s fastest-growing companies.

## Your Role

As a Forward Deployed Engineer for our for our Polish market, you work directly at the intersection of product and customer setups. You capture requirements, translate them into robust implementations, and take fonio live at customers – including integrations, automations, and ongoing optimization. You work closely with Product/Engineering and Go-to-Market, making sure deployments are fast, stable, and repeatable across the Polish market. This is a Warsaw-based role, ideally suited to someone who can operate natively in Polish.

## What you'll do

- Capture customer requirements and translate them into concrete implementation plans
- Build and roll out fonio setups in production: workflows, logic, prompts, guardrails
- Implement integrations with third-party systems (APIs, webhooks, CRM, calendar, ticketing, etc.)
- Develop smaller features and glue code to cleanly map customer cases
- Debug under production conditions: calls, flows, edge cases, fast fixes
- Build reusable templates and deployment playbooks to make setups scalable
- Deliver product feedback: bring pain points and feature gaps to the team, prioritized and concrete

Who we're looking for

- Solid coding skills: you can implement independently, not just configure
- Strong understanding of AI systems and LLMs (prompting, tool-use, RAG, failure modes)
- Workflow thinking: translate complex processes into robust, testable flows
- Experience with APIs, webhooks, auth, and common integration patterns
- Cloud fundamentals: deployments, observability, debugging in production
- Highly pragmatic working style: ship fast, make it stable, iterate
- Bonus: Voice/Telephony, n8n, TypeScript/Python, SQL, monitoring/tracing, GDPR
- Polish at native or near-native level & English fluent

## What we offer

- Competitive salary: €60,000–€85,000 per year
- Warsaw-based role, with relocation to Vienna for onboarding; we also have one of the coolest offices in Vienna's 7th district (lunch & dinner included)
- 100% Focus Time (no regular meetings)
- Unlimited budget when the ROI is right
- Extreme speed (we ship almost daily)
- Thousands of enthusiastic customers building the product together with us

Hiring Process

- 25 min intro
- 30 min deep dive with CTO & Co-Founder Matthias
- 20 min language check with Piotr
- 20 min culture fit with one of our founders

## About fonio

## Company Overview
- **One-liner**: fonio is a European AI platform that provides AI phone assistants and omnichannel customer communication solutions for small and medium-sized businesses.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: Vienna, Austria
- **Founded**: 2024
- **Founders**: Daniel Keinrath (CEO) and Matthias Gruber (CTO)

## Core Business
- **Primary industry**: AI-powered customer communication / Telecommunications
- **Target customers**: B2B, primarily small and medium-sized businesses (SMBs) with high volumes of customer calls
- **Mission or purpose statement**: To ensure no lead, customer, or opportunity is missed by providing 24/7 AI-powered communication across phone, WhatsApp, email, and chat.

## Products & Services
- **AI Phone Assistant**: An AI agent that handles inbound and outbound calls, capable of scheduling appointments, answering inquiries, processing orders, and transcribing conversations. It features speech recognition for difficult dialects, turn-detection for natural conversation flow, and real-time emotion recognition. It can be set up in under 10 minutes with no coding required.
- **Omnichannel Platform**: Expanding beyond voice to include WhatsApp (already live), with email and chatbot support to follow. The platform integrates with CRMs, calendar tools, and databases via native integrations and APIs.
- **Proprietary Calendar**: An AI-native calendar tool that is already live as part of the platform.
- **Proprietary CRM**: A CRM purpose-built for AI-driven customer interactions, expected to launch by the end of Q3 2026.

## Market Standing
- **Valuation/Market Cap**: $140 million valuation (as of June 2026, per seed round)
- **Key Metric**: Total funding of over $20 million, including a $17 million seed round led by 20VC (June 2026) and a €3 million angel round (December 2025).
- **Notable Investors/Partners**: 20VC (lead), with participation from founders and executives of Synthesia, HubSpot, and Revolut. Previous angel investors include early backers of Facebook and Airbnb.
- **Growth Signals**: 
    - Over 7,000 customers across nine markets (Austria, Germany, Switzerland, France, Italy, Poland, Brazil, UK, USA)
    - Automates over 2 million calls per month
    - Growing at roughly 40% month-over-month
    - Acquired competitor fluently in September 2025
    - Added $1 million in ARR in April 2026 alone, targeting a 5x increase by year-end
    - Opening offices in New York, Munich, Milan, Paris, London, Warsaw, and Barcelona

## Competitive Advantages
- **Proprietary European Infrastructure**: Develops its own orchestration layer and models (speech recognition, turn-detection, emotion recognition), ensuring all data remains in the EU on servers in Nuremberg, Germany. This differentiates them from competitors who white-label US services.
- **High End-to-End Resolution Rate**: In roughly 90% of cases, the AI agent conducts a fully human-like conversation and resolves the inquiry without needing to route it to a human.
- **Builder-Heavy Team**: Over half the team are former founders, operations leaders, or people who have scaled products at companies like Canva.

## Strategic Focus
- **Omnichannel Expansion**: Moving beyond voice to become a full omnichannel platform (WhatsApp, email, chat).
- **International Expansion**: Establishing physical offices in key markets (New York, Munich, Milan, Paris, London, Warsaw, Barcelona) after recent launches in the UK and US.
- **Building an AI-Native Tool Ecosystem**: Developing a proprietary calendar and CRM to create a complete, integrated platform for customer communication.

## Why Work Here
- **Rapid Growth & Impact**: The company is in a phase of hypergrowth (40% MoM), and employees are "still early enough that your work will genuinely shape the culture, the product, and the company." [fonio.ai/en/careers](https://www.fonio.ai/en/careers)
- **Culture**: Described as fast, committed, and in-office by default. The team emphasizes moving fast and having fun. Most roles are Vienna-based, with the expectation of being in the office most days.
- **Remote Options**: Engineering roles are fully remote (within ±3 hours of CET). For other roles, there is a temporary relocation to Vienna for onboarding (1-3 months), followed by relocation to the target market.
- **Relocation Support**: The company sponsors travel and accommodation in Vienna for the onboarding period and offers full relocation support for moving to target markets.
- **Team Size**: Around 40-50 people, with plans to double by the end of the year.
- **Hiring Process**: A 3-4 step process: 15-minute intro call, 30-45 minute skills interview (sometimes with a case study), potentially a deeper skills or leadership interview, and a final 20-minute culture call with both founders. [fonio.ai/en/careers](https://www.fonio.ai/en/careers)
