Our vision is to expand human capacity through superintelligence. And we're proving it's possible – through powerful, trustworthy AI that unites IT and business teams together to unlock enterprise-wide transformation. With WRITER's end-to-end platform, hundreds of companies like Mars, Marriott, Uber, and Vanguard are building and deploying AI agents that are grounded in their company's data and fueled by WRITER's enterprise-grade LLMs. Valued at $1.9B and backed by industry-leading investors including Premji Invest, Radical Ventures, and ICONIQ Growth, WRITER is rapidly cementing its position as the leader in enterprise generative AI. Founded in 2020 with office hubs in San Francisco, New York City, Seattle, Austin, Chicago, and London, our team thinks big and moves fast, and we're looking for smart, hardworking builders and scalers to join us on our journey to create a better future of work with AI. 📐 About the role We’re seeking a highly skilled fullstack software engineer to join our engineering team building advanced AI-driven agent systems that execute autonomous workflows, orchestrate multi-step tasks, and extend human capacity across enterprise applications. In this role, you’ll play a key part in designing, building, and scaling next-generation AI agents that integrate with enterprise data and services to solve real-world problems. You will collaborate with cross-functional teams to turn complex agent concepts into production-ready systems. 🦸🏻‍♀️ What you'll do - Design, implement, and maintain scalable, secure agent-driven services and systems that autonomously accomplish tasks using modern AI frameworks. - Develop and enhance robust infrastructure and high-throughput APIs, focusing on core agent capabilities such as memory, communication channels, skills, intelligent decision logic, security and workflow management. - Integrate agent capabilities with backend services, data stores, vector databases, search/retrieval systems, and external APIs. - Collaborate with product managers, AI researchers, data engineers, and UX teams to translate high-level agent use cases into robust, production-ready software. - Ensure reliability, monitoring, and observability for all agent components (metrics, logging, CI/CD, fault tolerance). - Contribute to architectural design decisions and participate in rigorous code reviews to uphold quality and maintainability. ⭐️ What you need - 3+ years of professional software engineering experience with strong proficiency (3+ years) in Python in production environments - Proficiency in native agentic coding, demonstrated through the daily use of tools like Cursor, Claude Code, and other agentic coding platforms. - Demonstrated experience building distributed systems, microservices, or complex backend APIs that support AI/agent workflows. - Solid expertise with systems that integrate AI models, agent frameworks (e.g., LangGraph, Agent Harness or platform-specific tooling), vector databases, and large context reasoning services. - Understanding of agent orchestration patterns, state management, and asynchronous workflows. - Experience with cloud platforms (e.g., AWS, GCP, Azure), containerization (Docker, Kubernetes), and operational engineering best practices. - Good grasp of performance optimization, testing frameworks, and CI/CD pipelines. - Excellent communication and collaboration skills, with a “connect + challenge + own” mindset. - Past work on AI agents that coordinate multi-step actions, reasoning, or autonomous decision-making loops. - Contributions to open-source agent toolkits or SDKs. - Experience with frontend technologies (React, TypeScript) for tooling around agent management interfaces. 🍩 Benefits & perks (UK full-time employees): - Generous PTO, plus company holidays - Comprehensive medical and dental insurance - Paid parental leave for all parents (16 weeks) - Fertility and family planning support - Early-detection cancer testing [through Galleri](https://www.galleri.com/partner/writer) - Competitive pension scheme and company contribution - Annual work-life stipends for: - Wellness stipend for gym, massage/chiropractor, personal training, etc. - Learning and development stipend - Company-wide off-sites and team off-sites - Competitive compensation and company stock options ## About WRITER ## Company Overview - **One-liner**: WRITER provides an enterprise AI platform that enables organizations to build, activate, and supervise AI agents grounded in company data and powered by its own family of large language models (LLMs). - **Entity Type**: Private (Series C; $326M total funding) - **Headquarters**: San Francisco, California, United States - **Founded**: 2020 - **Founders**: May Habib (CEO) & Waseem AlShikh (CTO) ## Core Business - **Primary Industry**: Enterprise AI / Generative AI Software Development - **Target Customers**: B2B; Large enterprises in regulated industries (e.g., financial services, healthcare, professional services). Named customers include Accenture, Mars, Marriott, Uber, and Vanguard. - **Mission Statement**: To expand human capacity through superintelligence by building trustworthy AI that unites IT and business teams for enterprise-wide transformation. ## Products & Services - **WRITER Platform**: An end-to-end platform for building, deploying, and monitoring AI agents that are grounded in enterprise data and governed by IT controls. Includes an "AI Studio" for custom agent creation. - **WRITER Agent**: A delegation-based agent that executes complex, multi-step workflows from natural language instructions (e.g., drafting reports, conducting research, generating compliant content). - **Palmyra Family of LLMs**: WRITER’s own suite of purpose-built LLMs, designed for transparency, reliability, and control in regulated environments. - **Security & Compliance Integrations**: Pre-built integrations with enterprise security, identity, and observability stacks (e.g., SSO, audit logs, role-based access controls) to meet compliance standards. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed (total funding of $326M). - **Key Metric**: Annual recurring revenue (ARR) estimated at $26M (source: LinkedIn company profile). - **Notable Investors**: Premji Invest, Radical Ventures, ICONIQ Growth, Insight Partners, Balderton Capital, B Capital, Salesforce Ventures, Adobe Ventures, Citi Ventures, IBM Ventures. - **Growth Signals**: Headcount of ~727 employees (+33.1% YoY); operates in 42 countries; LinkedIn followers grew +35.7% YoY to ~88k; expanding office footprint with hubs in San Francisco, New York, London, Chicago, and Austin. ## Competitive Advantages - **Five-year track record of in-house LLM R&D**: Co-founders have been building AI for enterprise since 2013 (first company focused on machine translation). WRITER controls its own model stack, not just a wrapper on third-party APIs. - **Enterprise-first DNA**: Platform is built from the ground up for governance, compliance, and IT integration — a key differentiator in regulated industries. - **Purpose-built for agentic workflows**: Unlike generic chatbot platforms, WRITER focuses on autonomous, multi-step task execution with deep domain context. - **Strong partner ecosystem**: Backed by a consortium of strategic investors including Salesforce, Adobe, Citi, and IBM, signaling deep enterprise channel potential. ## Strategic Focus - **Agentic AI for the enterprise**: Moving beyond simple prompting to autonomous agents that can be delegated complex tasks. - **Deepening IT and security integrations**: Making it easy for security and compliance teams to approve and deploy AI at scale. - **Expanding AI research**: Continuing to invest in the Palmyra family of LLMs to maintain frontier capabilities. - **Global expansion**: Growing presence across North America and Europe (offices in SF, NY, London, Chicago, Austin). ## Why Work Here - **Hybrid culture**: The company is built around a mix of in-office collaboration and remote work.
