About the Team DoorDash’s Internal Audit team provides independent assurance that the company’s risk management, governance, and internal control processes are operating effectively. We are a small team that is looking to expand and bring on motivated professionals. We don’t think of ourselves as a typical audit function - we are obsessively focused on risks to the organizations which reflects in the type of projects we support and execute. DoorDash is rapidly growing - we are expanding in multiple geos and launching new products. This exciting growth allows us to drive creative analysis, strategy, and solutions. Our focus areas include financial, operational, regulatory, security, IT, and more. About the Role We are seeking a Senior Director, IT Internal Audit to lead the strategy, execution and evolution of DoorDash’s global IT audit function. In this highly visible role, you will help shape the technology risk management practices across DoorDash - you will oversee a broad portfolio of audits, including IT SOX, cybersecurity, data governance, AI governance, and operational technology. You will report directly to the Chief Audit Executive and serve as a strategic advisor to DoorDash’s technology, security, and engineering leaders. You will bring deep technical audit expertise, exceptional leadership skills, and a passion for innovation to build and lead a world-class IT audit organization that scales with the business. This role demands someone who can balance strategy with execution (and isn’t afraid to roll up their sleeves) — a leader who can anticipate emerging technology risks, foster strong cross-functional partnerships, translate complex technical concepts into meaningful business insights, and be ready to operate at the lowest level of detail. You will partner with teams across Security, Platform Engineering, Data Engineering, Privacy Legal, AI, Product, and Compliance to strengthen our risk posture and drive a data-driven approach

Asana
📍 New York• Full-time• $202K – $230K/yr
10mo ago

The Product Management team drives Asana's product strategy and execution, translating customer needs and opportunities into a compelling roadmap and working cross-functionally to deliver impactful solutions for team productivity and collaboration. We're helping to define the Work Management category and inventing new ways for teams to work more efficiently together and see the larger purpose behind their work. Our team works directly with Engineering, Design, Experience Research, and Data Science, as well as with Sales, Support, and Marketing to ship great products. We're looking for a Senior Product Manager to join the team that enables customers to turn their work into concrete plans. This team owns the core surfaces people rely on to structure, organize, and view their work in Asana — including Pages, projects, list views, and My Tasks, among others — spanning both 0 → 1 experiences and deep, high-stakes improvements to workflows that millions of teams use every day. Because these surfaces are foundational to how people work in Asana, decisions here ripple across nearly every other team at the company, and this role requires aligning multiple partners around complex, sometimes ambiguous tradeoffs. This role is based in our New York City office with an office-centric hybrid schedule. The standard in-office days are Monday, Tuesday, and Thursday. Most Asanas have the option to work from home on Wednesdays. Working from home on Fridays depends on the type of work you do and the teams with which you partner. If you're interviewing for this role, your recruiter will share more about the in-office requirements. What you’ll achieve: Set the strategy for a program or large workstream within our core planning experience, aligned with broader group goals Drive end-to-end delivery of multi-month initiatives — from problem definition through launch — often defining work that lands on other teams' roadmaps and requires coordinating delivery across multiple teams, rather than

Anyfin is building the next generation of consumer finance. We’re profitable, scaling quickly, and now operating with a banking license which opens up a lot of technical complexity. We’re looking for a senior fullstack engineer who enjoys moving fast, taking real ownership, and building things that actually have an impact. If that sounds like your kind of environment, keep reading. Because honestly, it’s not a role for everyone. Small team, high responsibility We hire carefully. We’re not a company that grows by adding headcount everywhere, we grow by keeping the bar high and building a team where every person matters. This isn’t a place where you disappear into a big org. If you join, you’ll have real influence on what we build and how we build it. What you’ll do You’ll work across the stack, end to end: Build and ship features across backend, web and mobile. Own projects from idea to production (and beyond). Make product and technical decisions, not just implement tasks. Build systems that scale with real users and real money. Work closely with product and design, in person, every week. Our main stack is TypeScript, Node.js, React, React Native. How we think about building We’re pragmatic. We like speed, but we also care about building things that last. AI isn’t a side tool here. It’s embedded in how we work helping engineers move faster, reduce friction and focus on solving meaningful problems. We’re looking for engineers who are curious about that shift and want to be part of it, rather than people who feel like good engineering means doing everything the hard way. No ego. Just good judgment and high output. You’ll thrive here if you… Have solid fullstack experience. Take responsibility naturally and don’t wait to be told what to do. Enjoy messy problems and figuring things out as you go. Like being in an ambitious and collaborative team. Want to build, not just maintain. You’re comfortable with things like: Backend microservice architecture and API design. Reac
