Every 10 minutes, 18 million conversations happen between businesses and consumers around the world.
For decades, the consumer side of those conversations sucked: long queues, robotic menus, repeated explanations, and advice that
is often unhelpful. Most people today still cannot simply say what their problem is in natural language when communicating with
businesses.
AI changes that. For the first time, companies can have natural conversations with customers at massive scale. Every B2C company -
from energy providers to telcos to insurers - will use AI agents to talk to their customers. The number of conversations
businesses will handle is going to explode in the coming years.
At telli, we are solving the challenges that come with that shift. Today, leading B2C companies like Sky are already using telli
to deploy thousands of voice agents to provide their customers with a new experience. But building a first voice agent is easy,
getting it to drive real outcomes for customers and businesses is the hard part. telli helps companies build, deploy, and improve
consumer-facing AI voice agents at scale. This will become one of the most important software categories of the next decade, and
we intend to win it.
We are a small, AI-pilled team that likes to solve hard problems. Be it engineering, product, or GTM - we build, experiment, and
move fast, while heavily leveraging the capabilities of AI models. All of us like to challenge ourselves and take real ownership
over what we do, all while still staying humble and keeping a low-ego culture.
Check out our principles to see how we work.
As the Founding GTM Engineer you build the foundation to scale telli's go-to-market. You shape the telli playbook and turn it into
a scalable, automated system. As the GTM counterpart to the founding team and GTM lead, you power the sales function to help telli
grow.

We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster. We are looking for a builder, not just a manager. As the Team Lead for Business Development based in Berlin, you will hold a dual mandate: Coach the talent and Engineer the GTM strategy. You will lead the team responsible for the DACH, CEE, and Nordics regions, markets that require distinct strategies and precision. We are moving beyond standard "SDR" motions. We need a leader who can analyze signal patterns, partner with RevOps to automate workflows, and provide our Heads of Sales with predictive insights on which verticals will trend next. What you’ll do * Lead & Develop (The People): Recruit, hire, and coach a high-performing team of 9 Business Development Representatives (BDRs). You won’t just track KPIs; you will dissect calls, refine commercial judgment, and help BDRs "create their own path" toward closing roles. * GTM Architecture (The Engine): Act as the "GTM Engineer" for your region. Work with RevOps to optimize lead routing, data enrichment, and dashboarding. If the process is broken, you don't just report it: you fix it. * Strategic Forecasting: Partner with Sales, Marketing and Product Marketing to tailor our go-to-market strategy per vertical. You will identify future trending sectors in DACH/CEE/Nordics before they hit the mainstream news. * Data-Driven Experimentation: Embed a culture of A/B testing. Use data to refine messaging and targeting. You will be the bridge between the qualitative feedback of the BDRs and the quantitative rigor of our systems. * Cross-Border Collaboration: Champion the "Global License to Operate." Ensure your team collaborates effectively with Industry Leads, Head of Sales and Country Managers, adhering to our rules of engagement and Salesforce hygiene is non-negotiable. Who you are * You have 3+ years in Sales/Business Development, with at least 1+ year leading a team or driving complex GTM projects. * You are comfortable with the "Ops" side of sales. You understand that Salesforce is the source of truth and know how to leverage tools to uncover bottlenecks. * You drive performance through empathy and radical candor ("Talk straight without being rude"). You build teams that win together. * You can look at a list of 100 accounts and explain why we should prioritize the top 10 based on market signals, not just guesswork. * You are fluent in English and German. Experience working across CEE or Nordic markets is a significant plus. Our Diversity, Equity and Inclusion commitments Our unique approach is a product of our diverse perspectives. This diversity of backgrounds and cultures is essential in helping us maintain our momentum. Our business and technical challenges are unique, and we need as many different voices as possible to join us in solving them - voices like yours.

WHO WE ARE Foundation models transformed text and images. Structured data - the largest and most consequential data format in the world - stayed untouched. Tables run every clinical trial, every financial model, every scientific experiment, every business decision, and no one had built a foundation model that truly understood them. Until now. What LLMs did for language, we're doing for tables. The next modality shift in AI is happening, and we're hiring the team that makes it. Momentum. We pioneered tabular foundation models and are now the world-leading organization in structured-data ML. Our TabPFN v2 model was published as a Nature cover story and set a new state of the art for tabular machine learning. Since release we've scaled model capabilities 20x+, passed 3.5M+ downloads and 7,500+ GitHub stars, and are seeing accelerating adoption across research and industry - from detecting lung disease with Oxford Cancer Analytics to preventing train failures with Hitachi to improving clinical-trial decisions with BostonGene. The hardest work is ahead. We're scaling tabular foundation models to millions of rows, thousands of features, real-time inference, and entirely new data modalities, while building the infrastructure to run them in production across some of the most demanding industries on earth. These are open problems no one else is working on at this level. Our team. We're a small, highly selective team of 30+ engineers, researchers, and GTM specialists, with backgrounds spanning Google, Apple, Amazon, DeepMind, Meta, Microsoft Research, G-Research, Jane Street, Goldman Sachs, and CERN. We're led by Frank Hutter, Noah Hollmann, and Sauraj Gambhir, and advised by world-leading AI researchers including Bernhard Schölkopf and Turing Award winner Yann LeCun. We ship fast, do top-tier research, and hold each other to an extremely high bar. What's next. In 2025 we raised €9m pre-seed led by Balderton Capital, backed by leaders from Hugging Face, DeepMind, and Black Forest Labs. The next phase of growth is here, which makes this an ideal time to join. ABOUT THE ROLE Tabular data breaks the assumptions that make scaling work for language and vision. There's no natural sequence, no spatial structure, no shared vocabulary across datasets. The architectures and scaling laws that power LLMs don't transfer. We've made the first breakthrough with TabPFN — but the hardest problems are still ahead. At Prior Labs, Research Engineers aren't supporting scientists — they are the science team. You'll design experiments, contribute to papers, and write the code that turns architectural ideas into trained models. We create cutting edge research because the same people do both. As an early team member, you'll have significant technical ownership and room to grow as we scale. The problems we're solving: * Scaling transformer architectures from 10K to 1M+ samples — without the structural assumptions that make language models scale * Building multimodal models that combine tabular, text, and numerical understanding * Making models efficient enough for real-world deployment — not just accurate enough for a paper * Designing architectures for time series, forecasting, anomaly detection, and multiple related tables Day-to-day, you'll design and test novel architectures, run ablations, analyze scaling behavior, and write the training and evaluation infrastructure that makes rapid experimentation possible. We hold software quality to the same standard as research quality. What We're Looking For * Master's or PhD in Computer Science or a related field, plus 3+ years of experience building ML systems in research or industry * Publications at top ML venues (NeurIPS, ICML, ICLR, etc.) or equivalent demonstrated research impact (widely used open-source, deployed systems) * Deep proficiency in Python, PyTorch, and the broader ML and data science ecosystem (scikit-learn, pandas, NumPy), with strong software engineering practices * Experience implementing and training neural network architectures — ideally transformers or foundation models * Solid understanding of training dynamics, scaling behavior, and common failure modes in deep learning systems * Genuine interest in model efficiency — making large models faster, more scalable, and practical to deploy Nice to Have * Experience at an early-stage startup or as a founding engineer * Contributions to open-source ML libraries or tools * Experience with model distillation, inference optimization, or on-device ML * Background in tabular data, time series, or other structured data — helpful but not required Life at Prior Labs We're a small, ambitious team solving one of the hardest problems in AI, and we're just getting started. You'll work closely with world-class researchers and builders who care deeply about the quality of their craft, the impact of their work, and the people they work with. We move fast, we think rigorously, and we take the time to do things right. If you're excited by hard problems, motivated by real-world impact, and want to be part of building something that matters, we'd love to hear from you. We're building our teams in Berlin, Freiburg, and New York and we believe that when you're working on something as hard and exciting as TabPFN, being in the same room matters. Most of our roles are based in one of our offices but great people come from everywhere, and in exceptional cases we're open to remote. This usually involves frequent travel to one of our offices and the whole company comes together regularly for offsites to think, build, and celebrate together. Our Commitments We believe the best products and teams come from a wide range of perspectives, experiences, and backgrounds. That's why we welcome applications from people of all identities and walks of life, especially anyone who's ever felt discouraged by "not checking every box." We're committed to creating a safe, inclusive environment and providing equal opportunities regardless of gender, sexual orientation, origin, disability, or any other trait that makes you who you are. We care about how your data is handled. Read our Recruiting Privacy Notice to see exactly what we collect, why, and how long we keep it.
