Risk Ledger

ABOUT US Risk Ledger is developing a network of connected organisations, all working together to defend against cybersecurity attacks in the supply chain. Organisations rely on us to establish trust, through sharing their security maturity and visualising the risks posed by their supply chain ecosystem. And we’re already trusted by customers like ASOS, British Airways, BAE Systems and the NHS. We are putting together an amazing and talented team from a diverse set of backgrounds and skillsets to drive us towards our vision. Risk Ledger is built on the respect we have for one another and our users, united by our shared values and mission. Every one of us is still learning: it’s how we grow as individuals. We’re curious. We’re ambitious. And we’re humble and honest. At Risk Ledger, we aim high to find the best solutions we can and always put our users first. THE ROLE: We're looking for a Senior Product Manager to join us for this next phase of growth; where we’ll be significantly evolving our core offering, expanding internationally and diversifying into new use cases. You'll own a product area with a clear outcome (rather than a prescriptive feature list), where you'll explore the problem space, synthesise evidence and inputs to identify the right opportunities, and work with the team to solve them at pace. You'll need to be skilled at employing best-practice product development for our stage of growth, and working within real constraints like technical debt while maintaining high velocity. You'll also collaborate with the wider product team to strengthen our practice, supporting process improvements and contributing to better cross-functional ways of working with Design and Engineering.   IN THE ROLE YOU WILL: * Own a strategic area of growth. You'll start embedded in one of our core squads, working hand-in-hand with engineers and designers to critique bets, drive execution, and solve real customer problems. * Collaborate to deliver step-changes in value. Though established and growing, we have a huge opportunity in front of us, so we’re looking to deliver big step-changes rather than incremental improvements. This will need strong collaboration both within the product teams, and across functions. * Improve how we work as we scale. Work alongside the rest of our Product team, Design and Engineering to improve how we collaborate cross-functionally, refining our approach to discovery and delivery, and establish patterns that work for our stage of growth. YOU’LL HAVE: * 7+ years’ commercial experience in Product Management, with significant time in early-stage B2B SaaS environments. Ideally this includes experience navigating phases of international and/or portfolio expansion, and times where you’ve taken high-level, ambiguous opportunity spaces, shaped, and delivered at pace. * The ability to operate at different altitudes, shifting between strategic and tactical work as needed, while crafting compelling narratives that explain the "why" behind your bets. * A bias for action, prioritising momentum and experimentation over perfection, with the ability to cut through ambiguity and move initiatives forward while managing risk appropriately. * A results-driven mindset, focused on delivering measurable outcomes that align with strategic objectives, using qualitative and quantitative data to guide decisions and assess success. * Strong stakeholder management across technical and commercial teams - able to translate between different perspectives, facilitate alignment, and build trust through clear communication and follow-through. YOU MIGHT HAVE: * Experience integrating LLMs or AI capabilities into products. * Product ops experience - such as improving product data tooling or feedback management systems. WHY YOU’D LOVE IT HERE: * Hybrid working! 2x days a week including Thursday (company day). * A people focused culture! We are HUGE on cross-team collaboration, and in the same vein also socialising amongst teams and departments, with a friendly open plan office to facilitate this. * Regular socials to unwind and have some fun! From ‘Sip and Paint’ to F1 Arcades, Cricket matches, summer parties and sports days. Whether you like to get involved or not, the option is there. * A dog friendly office… if you have a furry friend, they are VERY welcome to join the Risk Legend community. DIVERSITY COMMITMENT: At Risk Ledger, we’re building a world class team where people feel comfortable that they can be themselves. We are striving to create a workplace where people’s skills, personality and experience are recognised, promoted and valued, no matter their background. We offer equal opportunities without discrimination, and actively encourage applications from candidates of all backgrounds.   The perks: * 💰Competitive base salary * 📈Generous EMI equity package * 👌Private pension * ✈️28 days annual leave + bank holidays * 🏖Additional 30 days of unpaid leave per year to use as you wish * 🏥Private healthcare with AXA Insurance - including enhanced mental wellbeing coverage * 🏠Hybrid working policy, typically 2-3 days in the office * 👶Enhanced family (parental) leave - gender-neutral policy, 12 weeks paid leave * 👪5 days Caretaker's leave * 😷Enhanced occupational sick pay * 💻£500 WFH budget * 📚All the learning resources and books you want to aid in your personal development * 🎉 Regular socials to unwind and have some fun     Salary range £95,000—£110,000 GBP

Taskrabbit

ABOUT TASKRABBIT: Taskrabbit is a marketplace platform that conveniently connects people with Taskers to handle everyday home to-do’s, such as furniture assembly, handyman work, moving help, and much more. At Taskrabbit, we want to transform lives one task at a time. As a company we celebrate innovation, inclusion and hard work. Our culture is collaborative, pragmatic, and fast-paced. We’re looking for talented, entrepreneurially minded and data-driven people who also have a passion for helping people do what they love. Together with IKEA, we’re creating more opportunities for people to earn a consistent, meaningful income on their own terms by building lasting relationships with clients in communities around the world. Taskrabbit is a hybrid company with employees distributed across the US and EU and a Built In — Best Places to Work (2022, 2023, 2024, 2025) continually ranked across multiple national and regional categories. Join us at Taskrabbit, where your work will be meaningful, your ideas valued, and your potential unleashed! This role operates on a hybrid schedule requiring two days in-office per week in our London office.   About the Role Taskrabbit connects busy people in need of help with trusted local Taskers who can lend a hand with everything from home repairs to errands, with the goal of being the number one home services platform in the countries we serve. A Tasker gets paid to do what they love, when and where they want, all while saving the day for someone in their city. The Tasker Operations team owns the Tasker experience end-to-end — from the targeted, locally-executed programs that drive quality, pricing, and utilization outcomes, to the funnel metrics and cross-business partnerships (e.g., Marketing, IKEA) that connect Tasker-side actions to company outcomes. We proactively help Taskers before they realize they need support, with global and local approaches that result in higher quality, more retentive, and more satisfied Taskers. This drives a better client experience and supports our overall managed marketplace strategy.   This is a highly visible, operationally-focused role and the primary owner of Tasker supply-demand balance in your region. You will own Tasker operations across a broad, complex Book of Business, set the strategy for supply health and supply-oriented fulfillment, and own the recommendation set that clients see in order to ensure high quality fulfillment. We’re looking for someone who is as energized by a live Tasker workshop as they are by an insightful dashboard — you don't just analyze the Tasker experience, you actively seek out time with them. You will be expected to operate with a high degree of autonomy and influence by independently scoping and executing high-impact projects, owning measurable outcomes, and building scalable systems and tools (including AI-powered tooling and automation) that are adopted beyond your own region.    You will be the face of Taskrabbit to Taskers in their market, a trusted advisor to your Regional Manager and Market Manager stakeholders, and seen as both a regional and functional expert across the organization.   This is not a supervisory role.   What You'll Do * Serve as the operational owner of Taskrabbit supply the UK, monitoring and reporting on performance and health metrics across your metros. Responsible for ensuring the quality of the recommendation set that clients see. Oversee supply lifecycles, programs, and communications to ensure a high-quality, continuous flow of Taskers and strong fulfillment. In partnership with Country or Regional management, set market strategy to drive invoices and revenue. * Use data to drive decisions: develop your own dashboards and analyses to inform strategies, plans, and tactical initiatives that you will develop; leverage data to surface problems worth escalating and either take action or successfully advocate for their prioritization with cross-functional partners. You will run experiments to drive impact in your region.  * Develop and execute tactical plays (in-app/push communications, email, etc.) based on supply needs and market insights to drive supply alignment, behavior change, and growth. Own the resulting playbooks so wins scale beyond your own metros. * Coach and grow your Tasker base — primarily in group settings, in person, and live virtually — bringing real energy and presence to every engagement with Taskers so they leave more motivated than when they arrived. Ensure consistent and effective delivery of lifecycle programs and enablement content (e.g. workshops) that measurably improve funnel outcomes like fulfillment and quality. * Lead local community engagement (events, office hours, Tasker socials) and mentor peers on coaching techniques and community-building. * Partner with the Senior Supply Specialist to address supply gaps through targeted acquisition and onboarding. * Align your Taskers with broader Taskrabbit processes, standards, and tools, ensuring they understand and adhere to updated expectations as the platform evolves. * Serve as a product and process expert: influence roadmap priorities with Product, escalate and advocate for bug fixes, partner with Tasker Quality on reliability and compliance, and build automation or AI-powered tools to scale your own and the team's impact. * Build cross-functional relationships (Product, Analytics, Engineering, Customer Support, Partnerships, Marketing, Legal, Commercial Operations) to advocate for Taskers and drive outcomes, including consulting on partnership assessments and launches. * Take on strategic ownership beyond your core scope — leading regional or company-wide programs and acting as a force multiplier through special projects and knowledge-sharing with the global team. * Champion culture and values through leadership, and keep local operations aligned to evolving global standards and tools. * Travel up to 10% to attend team and metro-specific events. * Adapt to evolving business needs, taking on other duties as necessary. About You * Bachelor's degree or equivalent experience. Fluent in English.  * 6+ years in marketplace operations, program management, or customer success, with a track record of taking on progressively larger scope — owning multiple metros or a large Book of Business with measurable impact on supply health, retention, revenue, or quality. * Advanced, independent data user who builds their own analyses rather than just reading dashboards, with strong SQL/Sigma skills and a knack for uncovering issues others miss. * A seasoned strategist who builds, executes, and rigorously measures the impact of initiatives from start to finish. * A hands-on operator who rolls up their sleeves, is comfortable moving between strategy and execution to drive real outcomes, and is driven to find ways to automate, streamline, and build new tools (including AI tools) that accelerate impact. * Confident and highly effective communicator who can influence senior stakeholders and present to audiences of any size, virtually or in person. * Genuinely energized by talking with Taskers — you seek out the tough conversation or the packed room rather than avoiding it, and enjoy uncovering the story behind the data. * Naturally curious and resourceful, with a strong instinct to investigate problems from multiple angles and uncover root causes, and always on the lookout for smarter, more creative solutions that challenge the status quo. You don't wait for perfect data or perfect conditions to move; when a market is stuck, you find a scrappy way to get it unstuck. * Self-starter and low-ego collaborator, unflappable under ambiguity or change, who thrives in fast-moving, globally distributed teams. * Energized by the challenge of finding opportunities to grow your market faster and drive innovative solutions at scale. * Deeply customer-centric, organized, and detail-oriented.   Nice to Have - Marketplace or gig-economy background. - Additional language fluency.   Our Values We are guided by five core values: Be Bold, Own the Challenge, Win Together With Heart, Move Forward, Move Fast, and Obsess Over Clients and Taskers. These principles shape every decision we make, fueling experimentation, ownership, empathetic collaboration, rapid iteration, and an unwavering focus on delivering exceptional experiences for both clients and Taskers.   COMPENSATION & BENEFITS:  At Taskrabbit, our approach to compensation is designed to be competitive, transparent, and equitable. Total compensation consists of base pay + bonus + benefits + perks. The base pay range for this position is £50,000–£70,000.
