About Us We are are building an agentic AI & intelligence platform for sustainability action and decision-making. Organisations today are drowning in fragmented environmental data - carbon, biodiversity, water, policy, supply chains & more - but still struggle to answer the most important questions: What should we do next? What s the impact if we do? What s the return on action - financially and environmentally? Our startup exists to close that gap. We are building a workflow and decision making layer on top of sustainability data: AI agents that ingest messy real-world inputs, reason over them, run scenarios, recommend actions, and learn from outcomes over time. All while building up a knowledge and context graph to build the single best view of how the organisation works today. This is from a team who has worked in the sustainability space for years and have successfully exited a prior business to one of the largest businesses in the world. We re now taking that learning and building the AI-native version of sustainability consulting. The Role We re looking for Founding Full Stack AI Engineers who want to build agentic systems from the ground up. You ll work at the core of our platform - designing and implementing AI systems that: Ingest and structure unstructured sustainability data Reason across complex, uncertain domains Run simulations and scenario analysis Support multi-step decision-making workflows Improve continuously via feedback and memory You ll have real ownership, real influence on architecture, and direct exposure to customers and domain problems. Our key focus is to take our prototype and turn it into something we start to deploy, test and scale with customers. What We re Looking For Essential Strong software engineering fundamentals 7+ years building full-stack applications Proficiency in modern web technologies - ideally in React/Next.js/TypeScript Experience with backend development using Python Comfort working with messy, real-world data Clear communicator who can design, architect and explain complex systems Use of coding agents to accelerate work (Codex/Claude Code) Strong Plus Experience building agentic workflows that are trusted Experience with LangChain, LangGraph, or similar Experience building with vector databases, embeddings, RAG pipelines Experience with graph databases Experience building simulation, optimisation, or decision-support systems Prior startup or early-stage experience Why Join Us Work on problems that actually matter - climate, nature, social risk Build cutting-edge agentic systems Strong influence in early key decisions Meaningful equity at an early stage Work with a passionate team of successful founders Additional Application Instructions Please do drop us an email. We'd love to hear about your passion for sustainability and your experience of designing data models, architecting platforms and building from zero to one? What do you think about the latest generation of coding LLMs - good, bad, what have you used?

Vanta
At Vanta, our mission is to help businesses earn and prove trust.We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. Our business has found incredible product-market fit and has monetized effectively since the day we signed our first customer. We're growing at a blistering pace, which presents career-defining opportunities for engineers to accelerate their growth and to contribute to a rapidly-scaling company. We are hiring Senior Fullstack Product Engineers (React, Typescript, Node, GraphQL & MongoDB) to build emerging products and to contribute to efforts to build features used across our Product Platform; applications through this link put you into consideration for the following teams: Third Party Risk Management: This product was designed to provide software buyers with tools to evaluate the security of their vendors and partners by inventorying vendors, prioritizing risks, automating security reviews and remediating findings. TPRM or Third Party Risk Management (TPRM) presents a massive opportunity for Vanta - representing a market of $5-$10B in ARR and a CAGR of 10.8% driven by secular tailwinds in the industry that requires more focussed and deeper scrutiny of the company's supply chain. Monetization: This team is building an enterprise-grade revenue and entitlement platform to support our rapid upmarket expansion. Serving as the critical bridge between our core product and revenue operations, you will build resilient backend systems in our product platform that integrate seamlessly with tools like Salesforce, NetSuite, Ironclad, and Metronome. You'll tackle complex distributed systems challenges to establish Vanta's entitlement source of truth, enable customer purchasing and trial experiences, and manage usage-based billing. You will have an impact on the entire customer lifecycle, including domain provisioning and management, and work closely with Expansion to support core checkout plumbing and account management capabilities on our billing page. Your work on this scalable commercial infrastructure will directly accelerate Vanta's growth. Expansion: This team focuses on the full post-activation lifecycle-driving retention, expansion, and revenue automation across the product. You'll build the core systems that power Vanta's purchasing, trial, and renewal experiences for existing clients.This includes creating seamless checkout flows, self-serve upgrade paths, and intuitive renewal pages, as well as integrating with our evolving billing infrastructure. You'll also develop the platform that enables "try before you buy" experiences across Vanta, giving prospects hands on access and empowering other product teams to plug into a unified trials framework. Collaboration: On the Collaboration team, you will contribute to building components and APIs that make it more efficient for Vanta users to complete GRC and Trust management tasks. We believe in building these components and APIs in a way that makes them easy to adopt by other engineering teams within Vanta. Customer Trust Automation: This team is responsible for delivering experiences that reduce sales friction, automate inbound customer security assessments, and foster durable, high-trust relationships - through products including the Trust Center, Questionnaire Automation, and emerging agentic experiences. What you'll do as Senior Software Engineer at Vanta: Lead complex projects with multiple stakeholders and engineers to accelerate our roadmap and land impact faster. Collaborate with other teams and engineers across Vanta on cross-cutting engineering initiatives or on building common product primitives. Mentor engineers up to your own level; assigning them tasks and helping them develop their skills over the course of each project.

Offices in SF, NYC, London, Dublin, Tel Aviv, and Sydney About Vanta We started in 2018, in the wake of several high-profile data breaches. Online security was only becoming more important, but we knew firsthand how hard it could be for fast-growing companies to invest the time and manpower it takes to build a solid security foundation.Vanta was inspired by a vision to restore trust in internet businesses by enabling companies to improve and prove their security. From our early days automating security monitoring for compliance standards like SOC 2, HIPAA and ISO 27001 to creating the world's leading Trust Management Platform, our vision remains unchanged. Now more than ever, making security continuous-not just a point-in-time check- is essential. Thousands of companies rely on Vanta to build, maintain and demonstrate their trust- all in a way that's real-time and transparent.
