Location: Georgia; Macedonia; Kosovo; Romania; Montenegro; Serbia; Slovenia; Czech Republic; Remote, EMEA Workplace: remote Back in 2017, Belkins started as an appointment-setting agency with just one service offering. Fast forward to today, and we’ve transformed into Belkins Group—a vibrant ecosystem of services and products that define the cutting-edge landscape of the SalesTech and MarTech industries. Among our successes are ambitious start-ups like Revit, which have evolved into standalone powerhouses, as well as innovative products such as Folderly. At Revit, we believe in a future where high-end, results-driven lead generation services are accessible and adaptable to companies of all sizes and life stages. We’re a rapidly growing company (“startup” by energy but “matured company” by expertise and seniority) working with SMB clients and helping them grow through outbound campaigns. With a team of over 20 extremely talented people on our main team and with more extensive support from other companies of Belkins’ group of companies, our 2026 goal is to double in size and find a way to keep scaling while keeping high-quality across the board - from having the best people on the team to onboarding the right clients matching our values and value proposition. This is not a place for everyone but if you’re looking for a World-Class culture and opportunity to grow, build your career, make an impact, then you are likely to enjoy being a part of Revit and building the future together with us! This is an extremely fast-paced and dynamic environment. We move quickly, iterate constantly, and expect our team to keep pace without hand-holding.   This is not a traditional "Account Management" role - it is a performance-heavy role where you own the delivery of an outbound engine.   We don’t just need executors; we need experts. We expect you to come to the table with a strong, informed opinion on "what works." You are here to lead the strategy, not just follow a checklist. We provide the platform for you to go from Great to Excellent, but you must start at a high level of mastery from Day 1.   Our Co-Founder/CEO - Nick, and Lead of the team - Oleksandra - recorded a brief intro + role overview video — watch it on YouTube WHAT WILL YOU DO? Be the Project Owner: Manage 4–5 projects as the lead strategist. You aren't just the contact person; you are the driver of the vision and the primary decision-maker for project success. High-Volume outreach: Oversee 12–20 campaign launches total per month. This includes crafting high-converting copy and building complex templates based on your deep understanding of market triggers. Drive the numbers: With 2,000–3,000 contact imports per project monthly, your focus is sharp: booking 5+ high-quality appointments per project. Consultative leadership: Lead weekly client calls. You aren’t just a reporter; you are a growth partner who provides expert recommendations and challenges the status quo when necessary. Lead your crew: Guide your dedicated Researcher to ensure data accuracy and keep the project on schedule. Master the tech stack: Handle the technical backend of multiple campaigns (managing dozens of mailboxes, ensuring deliverability, and mastering HubSpot/spreadsheet integrations). WHAT SHOULD YOU HAVE? 3+ years in performance-driven sales: You've spent real time in BDR, SDR, BDM, or AM roles where numbers mattered . You don't need to have started in research, but you know how to build and scale a sales motion that actually works. Strategic confidence: You can defend your strategy to stakeholders and back up your recommendations with data that moves the conversation forward. Deep tech fluency: You're a power user of CRM and automation tools. You understand the technical side of cold outreach and can troubleshoot tool stacks on the fly without filing a support ticket. High-Stakes Client Management: You've managed senior client expectations and led strategic sessions in professional, pressure-heavy environments. Speed & Leadership under pressure: You thrive in fast-moving environments. You stay organized when things get chaotic and you're ready to step up as a mentor and leader when the team needs it. Fluent English (C1/C2): Clear, persuasive, and confident communication is second nature to you. You write tight recaps, lead sharp calls, and present strategy like you've done it a hundred times. Analytical by default: When KPIs dip, you don't wait for instructions. You dig into the data, find the lever, and adjust the approach before anyone has to ask. Note: If you're looking for a slow-moving, relationship-first role, this isn't it. We want someone who's already a strong operator in the sales process and ready to level up. At Belkins Group, we care deeply about our team members, and we prove it through: Competitive Pay: Your dedication deserves more than recognition; it deserves compensation that matches your expertise. Remote-First Flexibility: We’ve transitioned to a fully remote environment so you can work where you’re most productive. Our flexible hours help you stay agile and focused. Professional Growth: We’re a launchpad for your career. Through regular feedback, 1:1s, internal mobility, and knowledge-sharing, your growth is enabled and celebrated.

Location: San Francisco, CA About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. Note: we don't have open Research Manager positions on the Interpretability team at this time. However, we're actively growing our team of Research Engineers and Research Scientists . If you're excited about interpretability research and open to an individual contributor role, we encourage you to apply. About the Interpretability team When you see what modern language models are capable of, do you wonder, "How do these things work? How can we trust them?" The Interpretability team’s mission is to reverse engineer how trained models work, and Interpretability research is one of Anthropic’s core research bets on AI safety. We believe that a mechanistic understanding is the most robust way to make advanced systems safe. People mean many different things by "interpretability". We're focused on mechanistic interpretability, which aims to discover how neural network parameters map to meaningful algorithms. Some useful analogies might be to think of us as trying to do "biology" or "neuroscience" of neural networks, or as treating neural networks as binary computer programs we're trying to "reverse engineer". We aim to create a solid scientific foundation for mechanistically understanding neural networks and making them safe (see our vision post ). We have focused on resolving the issue of "superposition" (see Toy Models of Superposition , Superposition, Memorization, and Double Descent , and our May 2023 update ), which causes the computational units of the models, like neurons and attention heads, to be individually uninterpretable, and on finding ways to decompose models into more interpretable components. Our subsequent work which found millions of features in Claude 3.0 Sonnet, one of our production language models, represents progress in this direction. In our most recent work , we developed methods that allow us to build circuits using features and use these circuits to understand the mechanisms associated with a model's computation and study specific examples of multi-hop reasoning, planning, and chain-of-thought faithfulness on Claude Haiku 3.5, one of our production models.” This is a stepping stone towards our overall goal of mechanistically understanding neural networks. A few places to learn more about our work and team are this introduction to Interpretability from our research lead, Chris Olah, Stanford CS25 lecture given by Josh Batson, and TWIML AI podcast with Emmanuel Ameisen. Some of our team's notable publications include and our Circuits’ Methods and Biology papers, Scaling Monosemanticity: Extracting Interpretable Features from Claude 3 Sonnet , Towards Monosemanticity: Decomposing Language Models With Dictionary Learning , A Mathematical Framework for Transformer Circuits , In-context Learning and Induction Heads , and Toy Models of Superposition . This work builds on ideas from members' work prior to Anthropic such as the original circuits thread , Multimodal Neurons , Activation Atlases , and Building Blocks . About the role As a manager on the Interpretability team, you'll support a team of expert researchers and engineers who are trying to understand at a deep, mechanistic level, how modern large language models work internally. Few things can accelerate this work more than great managers. Your work as manager will be critical in making sure that our fast-growing team is able to meet its ambitious safety research goals over the coming years. In this role, you will partner closely with an individual contributor research lead to drive the team's success, translating cutting-edge research ideas into tangible goals and overseeing their execution. You will manage team execution, careers and performance, facilitate relationships within and across teams, and drive the hiring pipeline. If you're more interested in making individual direct technical contributions to our research as the primary focus of your role, feel free to apply to our Research Scientist or Research Engineer roles instead. Key responsibilities Partner with a research lead on direction, project planning and execution, hiring, and people development Set and maintain a high bar for execution speed and quality, including identifying improvements to processes that help the team operate effectively Coach and support team members to have more impact and develop in their careers Drive the team's recruiting efforts, including hiring planning, process improvements, and sourcing and closing Help identify and support opportunities for collaboration with other teams across Anthropic Communicate team updates and results to other teams and leadership Maintain a deep understanding of the team's technical work and its implications for AI safety You may be a good fit if you Are an experienced manager (minimum 2-5 years) with a track record of effectively leading highly technical research and/or engineering teams Have a background in machine learning, AI, or a related technical field Actively enjoy people management and are experienced with coaching and mentorship, performance evaluation, career development, and hiring for technical roles Have strong project management skills, including prioritization and cross-functional coordination and collaboration Have managed technical teams through periods of ambiguity and change Are a quick learner, capable of understanding and contributing to discussions on complex technical topics and are motivated to learn about our research Are a strong communicator both in speaking and in writing Believe that advanced AI systems could have a transformative effect on the world, and are passionate about helping make sure that transformation goes well Strong candidates may also have Experience scaling engineering infrastructure Experience working on open-ended, exploratory research agendas aimed at foundational insights Some familiarity with our work and mechanistic interpretability Role-Specific Location Policy This role is expected to be in our SF office for 3 days a week. The annual compensation range for this role is listed below. For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role. Annual Salary: $350,000 — $500,000 USD Logistics Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices. Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this. We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed.  Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team. Your safety matters to us. To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses.

Legitimate Anthropic recruiters will never ask for money, fees, or banking information before your first day. If you're ever unsure about a communication, don't click any links—visit anthropic.com/careers directly for confirmed position openings. How we're different We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences. Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
