And we're just getting started. \nBacked by Greylock and Y Combinator, fully remote since 2018.\nWe are looking for a polyglot Senior Fullstack Engineer to join the Customer Context team. You’ll help build and scale the foundational services, APIs, and pipelines that power the Postscript product. This role blends strong backend engineering skills with a deep appreciation for data intensive systems, performance, and reliability. You’ll collaborate closely with other software engineers, data engineers, and product to help e-commerce marketers maximize their revenue with best-in-class targeting and context-driven AI.\nThis is a high-autonomy role for engineers who are energized by ambiguity, take genuine ownership of their work, and bring a strong point of view on how to build things well, without sacrificing speed or pragmatism. AI isn't a nice-to-have here - it's central to how we work. We expect our engineers to be active practitioners of AI-first development: fluent with the latest agentic coding tools, curious about what's emerging, and constantly pushing the boundary of what's possible with AI in their day-to-day craft. If you're the kind of engineer who's already experimenting with new models and tooling before anyone asks you to, you'll feel at home here.\nAs a senior engineer at Postscript, you’ll no longer be only writing code but orchestrating it. \nThis position is fully remote and can be based in the US or Canada.\nWhat You'll Do\nTake deep ownership of systems and product areas on your team, and become the go-to technical expert for what you own\nIndependently investigate, design, and execute solutions across distributed systems with a high degree of ambiguity\nArchitect, build, and maintain highly available, scalable REST APIs and backend services for internal and external use\nDrive system decoupling, modularization, and technical debt reduction.. Improve long-term maintainability without blocking near-term delivery\nBuild agentically as your default: leveraging concurrent autonomous agent workflows, owning the output, and keeping a steady queue of aligned work moving\nStay at the forefront of emerging AI tooling and practices, bringing new techniques back to the team and helping raise the floor for how Postscript engineers work\nContribute to how we think about integrating AI into our systems and workflows. That means not just using AI tools, but helping shape where and how AI creates leverage across the engineering org\nCollaborate cross-functionally with product, data, and go-to-market teams by communicating clearly and proactively in an async-first environment\nIdentify and eliminate single points of failure, improving system resilience and knowledge redundancy across your team\nImprove how engineering gets done: bring better tools, fix workflow friction, build internal utilities when the leverage compounds\nWhat We're Looking For\n6+ years of experience building large-scale data-intensive backend systems and APIs\nYou are an active, daily user of AI coding tools and are using them to maximize your output - Claude Code, Codex, Cursor, Copilot, or equivalent - and can speak concretely to how they've changed your output and your workflow\nSome or all of these languages: Python, Go, Rust, React, and TypeScript\nYou follow the AI tooling landscape closely: new model releases, emerging agentic workflows, and evolving best practices aren't things you catch up on eventually.\nYou think critically about AI output and you know where it accelerates you, where it introduces risk, and how to verify what it produces\nYou are able to context switch quickly across concurrent workstreams\nExperience working on both 0-to-1 initiatives and complex existing systems, and knowing how to balance building new things with improving what's there\nYou have working knowledge of event-driven distributed systems, Kafka, and familiarity with distributed data processing technologies (Flink/Spark/etc)\nExperience growing systems under production customer load, ideally from early days to the multi-terabyte stage\nExperience building and designing high-scale systems AWS with a broad variety of database technologies (RDBMS, OLAP, NoSQL, etc.)\nYou know how to intelligently model relational data and design index strategies. You write performant SQL for transactional and analytical workloads\nExperience with infrastructure as code (eg, Terraform). You are comfortable evaluating and applying your infra changes.\nFamiliarity building and observing applications on AWS & Kubernetes, ideally with Datadog, Signoz, or comparable observability tooling\nClear, direct communication. Cross-functional partners and async teams can count on you to surface information proactively\nStrong instincts for technical tradeoffs informed by both engineering best practices and business priorities\nWhat You'll Love About Us\nSalary range of USD $175,000-$205,000 base plus significant equity (we do not have geo-based salaries)\nHigh growth startup - plenty of room for you to directly impact the company and grow your career\nWork from home (or wherever in US / Canada)\nFun - we're passionate and enjoy what we do\nCompetitive compensation and opportunity for equity\nFlexible paid time off\nHealth, dental, vision insurance\nFor information about how we use your personal data, please see our U.S. Job Applicant Privacy Notice\nYou are welcome here.
