Role Description This is not a strategy role. It is not a coordination role. It is a get-in-and-do-it role for someone who wants real ownership, moves fast, and finds energy in problems that have never been solved before. You will own the important projects that currently have no clear owner. You will work directly with leadership on high-priority initiatives that are undefined by design, because they are new. Each project starts from scratch: new domain, new constraints, no template. You will figure out what the right question is, get smart fast, and drive it all the way to done. The best version of this person is someone who would rather build the map than wait for one. You do the research, write the recommendations, make the call, and keep moving. If you are looking for a role where you can put your head down and execute on work that matters, this is it. This role is best suited for those energized by fast-paced environments, excited to build in a high-growth setting, and deeply motivated by our mission. If you’re looking for meaningful challenges, dynamic work, and the opportunity to make a real impact — we’d love to meet you. Key Responsibilities - Own projects end-to-end. From scoping the actual problem to delivering a finished outcome. These initiatives are high-priority and undefined by design. - Do the work. Research new domains from scratch, structure the problem, produce real outputs: recommendations, plans, frameworks. Not summaries of what others should do. - Write clearly and drive alignment. Turn ambiguous situations into a point of view leadership can act on. Keep stakeholders informed and bring the right people in at the right time. - Make decisions and move. You will not have perfect information. You will make the call anyway and adjust as needed. - Work across functions. Operations, product, clinical, legal, finance. You go where the project needs you, not where the org chart points. - Drive multi-million dollar initiatives from concept through execution, staying accountable for outcomes at every stage. Qualifications - Doer first. You do not delegate the hard parts. You go deep, get your hands dirty, and produce work product others can act on. - Moves fast under uncertainty. Comfortable without a playbook. Makes good calls with incomplete information and adjusts quickly when things change. - Writes well. Clear, structured, direct. You can take a complex situation and turn it into something people can act on. - Strong judgment. Knows which details matter and which do not. Spends time accordingly. - High ownership. Full accountability for outcomes, not just effort. Takes initiative without being asked. - Mission-driven. Genuinely believes preventive healthcare is one of the most important problems to get right and wants their work to be part of making it real. Requirements - 7+ years of experience with a track record of owning hard, ambiguous problems and driving them to completion. - Has built something from scratch. A team, product, process, or business. Understands what zero-to-one actually requires. - Has managed complex, multi-stakeholder projects where they were the one holding the thread together. - Can point to specific examples of turning a vague, undefined problem into a clear path forward and then executing it. - Strong written communication. You can show your work, and it holds up. Benefits - Base Salary: $180,000 - $210,000 - Stock options - Comprehensive health, dental, and vision plans for you and your family - Wellness and commuter benefits - Competitive vacation policy - A culture that emphasizes learning - Professional development budget for continued learning - Opportunity to directly impact our mission of saving lives through early cancer detection

• Do you love crafting beautiful and functional customer experiences? • Want to work on interesting technical problems around booking flows and payments? • Do you have a passion for Elixir and functional programming but also love building complete experiences end to end? • You'll design and operate complex agent orchestration systems, develop patterns for human-agent collaboration, and ship real product features primarily through agent-assisted development in collaboration with human colleagues. • This role will primarily focus on the Customer Experience (B2B2C) side of the business, including building an elevated user experience in a new and improved greenfield booking flow.

WHO WE ARE At Basis, we empower agencies and brands with cutting-edge software that automates digital media operations. Our all-in-one platform supports seamless planning, reporting, and financial reconciliation across direct, programmatic, search, and social media. We’re not just building advanced technology; we’re also building a culture where passionate, motivated individuals come together to drive meaningful change. Our commitment to inclusivity and growth ensures our employees thrive both professionally and personally. With our headquarters in Chicago, we offer flexible work options across the U.S. and Canada, including remote, hybrid, or on-site at headquarters. ABOUT THE TEAM Technology is at the core of what we do. Basis is an industry-leading platform that automates and simplifies the entire digital ad campaign process. It processes over 300 billion events per day and uses AI and machine learning across the full campaign lifecycle. The Core Backend team is the connective tissue that keeps Basis running and enables other engineering teams to move faster. We own the core backend, the foundational customer-facing features developed within it, and the systems and standards that feature teams build on top of. We also define expectations for performance and reliability, observability foundations, and release tooling, along with the strategy for decomposing the system into well-defined microservices and evolving the application over time. If you're energized by platform-level problems, by setting the standards other teams build on, and by work whose outcome is other teams shipping faster, this is the team for you. WAYS YOU’LL CONTRIBUTE - Contribute to the platform's performance, observability, and reliability standards, and help drive adoption across feature teams. - Reshaping how we build and ship: CI/CD, trunk-based development, and developing a layered testing strategy (unit, integration, contract, end-to-end) so teams can test in isolation and deploy independently. - Collaborate closely with the Enterprise Developer Experience team to build shared tooling. - Improve the developer and pre-production experience for the core backend — pipeline design, environment stability, and a fast development feedback loop. - Lead platform projects across the stack — release tooling, platform reliability, and the patterns that guide how we decompose the core backend into services. - Take ownership of deliverables, quality, and on-call support across our systems and components, and drive projects from ideation through production. - Actively partner with the feature teams who depend on the systems you own — through pull requests, demos, design discussions, and identifying risks and blockers early. WHAT YOU BRING TO THE TABLE - 5+ years of professional software engineering experience. - Experience developing large-scale cloud-native systems — reliability, scalability, and the observability that keeps them healthy. - Depth in modern software delivery: CI/CD, trunk-based development, layered automated testing, and release practices like feature flagging, canary deployments, and progressive delivery. - Experience contributing to org-wide standards — testing strategy, environment management, performance and SLOs. - Fluency with AI coding tools (Claude Code, Cursor, Codex, etc.) as a core part of your development workflow — for code generation, debugging, exploring unfamiliar codebases, and documentation — paired with strong judgment for evaluating, refining, and taking full ownership of AI-generated output. - A thoughtful, collaborative approach to design and decision-making, and a commitment to inclusive environments where all voices are valued. OUR TECH STACK - Ruby, Rails, JavaScript, React, Java, Python - PostgreSQL, Redis, Kafka, RabbitMQ, Sidekiq - AWS, EC2, RDS, Docker, Terraform, Kubernetes - Datadog, Airbrake Integrity in Hiring At Basis, integrity is at the core of how we hire.
