You lead by building, debugging, reviewing, and shipping, not by staying removed from the systems you influence. * The ability to move into unfamiliar technical territory quickly, form strong opinions grounded in first principles, and help teams make better long-term decisions. ## Description We're looking for a Principal Software Engineer to help shape the technical future of Data Infrastructure at HubSpot. This is a deeply hands-on role for a builder who wants to own the architecture and evolution of the foundational data systems behind HubSpot's products. As a Principal Engineer, you will help define how our data stores should scale, how developers should interact with them, and what platform patterns we should create so teams across HubSpot can build faster on top of reliable, high-leverage infrastructure. At HubSpot, Principal Engineers are expected to stay close to the code, lead high-impact initiatives end-to-end, and influence technical direction well beyond a single team. This role is for someone who can move between storage engines, developer-facing platform design, and large-scale architectural bets while remaining a hands-on builder throughout. Key Expectations Own the future of HubSpot's data stores * Shape the technical direction for the data platforms that underpin HubSpot's products, with a focus on the data stores themselves and the systems around them. * Drive architectural decisions across storage, access patterns, scaling models, tenancy, performance, and developer ergonomics. * Help define what the next generation of HubSpot's database platform should look like, not just how to operate the current one. Be a deeply hands-on, high-leverage builder * Write production code regularly and lead complex initiatives from idea to rollout. * Build internal frameworks, APIs, and platform capabilities that make HubSpot's data stores easier to adopt, extend, and evolve. * Turn ambiguous infrastructure problems into simple, scalable systems and clear technical direction. Lead platform architecture across multiple domains * Work across big data, SQL/Vitess, batch, stream processing, and search to establish consistent platform patterns where they matter and domain-specific depth where they do not. * Define reusable abstractions for data storage, ingestion, processing, and access that reduce fragmentation across the engineering organization. * Push for simplicity, clarity, and extensibility in systems that can easily become overly bespoke or operationally heavy. Influence across the broader engineering org * Partner with engineering and product leaders to align infrastructure direction with what HubSpot needs to build next. * Work horizontally across teams to guide technical tradeoffs, unblock difficult decisions, and raise the architectural bar for platform work. * Act as a multiplier through design reviews, technical mentoring, and principled decision-making on the most important systems in the space. ## Related Videos - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Integrate your Cognitive Assistant with 3rd-party DBs and software](https://www.wearedevelopers.com/videos/249-integrate-your-cognitive-assistant-with-3rd-party-dbs-and-software) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) ## Related Articles - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
