At Sift, we're redefining how modern machines are built, tested, and operated. Our platform gives engineers real-time observability over high-frequency telemetry-eliminating bottlenecks and enabling faster, more reliable development. Sift was born from our work at SpaceX on Dragon, Falcon, Starlink, and Starship-where scaling telemetry, debugging flight systems, and ensuring mission reliability demanded new infrastructure. Founded by a SpaceX, Google, and Palantir team, Sift is built for mission-critical systems where precision and scalability are non-negotiable. About the Role As a founding Product Manager at Sift, you'll drive strategic, cross-functional initiatives that make our product more scalable, reliable, and impactful for mission-critical use cases. You'll define the roadmap for key areas of the product, translating high-level goals into clear, actionable plans that deliver real customer value. Partnering closely with engineering, design, and go-to-market teams, you'll ensure alignment and momentum across the organization. Your focus will be on strengthening the core of our platform-improving performance, usability, and resilience for our most demanding customers-while helping refine the strategy and processes to drive efficiency within our team. We're looking for a PM who thrives in dynamic, high-growth environments and wants to service industries like satellite constellations, renewable energy, and autonomous transportation. This is a rare opportunity to influence an early-stage company's success and direction. You will report to our Co-Founder and CTO and play a critical role in translating our long-term vision into a tangible product roadmap. In This Role, You'll: * Lead the vision, strategy, and execution of major initiatives within Sift's product, ensuring short-term tactics align with long-term goals. * Establish close relationships with customers to uncover their needs and validate opportunities. * Own the product development lifecycle from ideation to launch, ensuring alignment with company goals and user needs. * Collaborate with the go-to-market, design, and engineering teams to set priorities, optimize the product roadmap, and drive business objectives. * Conduct market research and competitive analysis to shape product strategy, identifying opportunities to expand value for existing customers and drive new revenue. * Set up instrumentation to measure and validate product value, ensuring product decisions are based on clear metrics. * Curate documentation and educate the go-to-market team on new features. The Skillset You'll Bring: * 5+ years of experience as a product manager with a proven track record of delivering complex B2B SaaS products. Experience at an early-stage startup is a strong plus. * An ability to synthesize myriad inputs and build a cohesive roadmap. * Strong customer empathy with a history of building relationships, conducting deep research, and translating insights into product features. * Proven ability to collaborate effectively across multiple teams and lead cross-functional collaboration without being a bottleneck. * Strong understanding of product prioritization frameworks and experience building products that deliver measurable value to customers. * Technical fluency, with the ability to discuss and align on engineering trade-offs and communicate technical concepts to various stakeholders. Bonus Points: * Experience in any of the following: * Data warehousing/lake housing (e.g. Snowflake, BigQuery, Iceberg) * Data job orchestration (e.g. Dagster, Airflow) * Batch and stream processing systems (e.g. Kafka, Spark, Flink) * Data cataloging, discoverability, and life-cycle management * Data science models, integrations, or data pipeline development (DBT, Fivetran, AirByte) * Enterprise SaaS cloud platform features, such as IAM, security, billing, and multi-tenancy. What We're Looking For: * Someone with a growth mindset who's excited to build, own, and evolve a product function within a high-growth start-up. * A PM who thrives in ambiguity and start-up chaos and who can build a structure where needed. * A business-savvy PM who can connect product decisions with business outcomes and is comfortable prioritizing based on P&L considerations.
