Senior Lead Java Full Stack Developer Jobs

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Company’s primary focus is to develop distributed power generators that can operate on various fuel sources to future-proof against an ever-changing energy economy. Job Purpose The Senior Supplier Quality Engineer owns the technical health of Hyliion's precision machining supply base and serves as the senior technical authority for machined content on the KARNO Power Module. Much of the machined content that determines whether a machine runs, including tolerances, surface finishes, form and runout requirements, and sealing surfaces, is produced by external partners, some of it on additively manufactured parts. This position sets the standard for how supplier quality is practiced at Hyliion, including the qualification evidence required, the inspection methods used, and the technical judgment applied when a part is borderline. The role works in both directions: outward, building engineering-grade partnership with machining suppliers and closing the gap between what drawings require and what supplier processes can repeatably deliver; and inward, holding Product Engineering, Quality, Supply Chain, and Operations accountable for releasable drawings, defined acceptance criteria, realistic schedules, and closed feedback loops. The position carries no authority over those functions and operates through technical credibility and evidence. AI at Hyliion At Hyliion, AI is core to how we work. We equip every team member with leading AI tools and count on you to use them — to move faster, solve harder problems, and help us realize the full potential of KARNO technology for the world. Duties and Responsibilities Serve as the engineering authority for machined commodities, including turning, milling, grinding, honing and lapping, EDM, balancing, deburring and edge condition, and associated special processes incl

About the team + role We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. Robinhood isn't a place for complacency, it's where ambitious people do the best work of their careers. We're a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards.

ABOUT THE TEAM The Integrated Workflows team exists to expand Mural's value by embedding it seamlessly into the essential business workflows our customers already live in. We connect Mural to the tools that teams rely on every day, from the systems of record where work gets tracked to the places conversations happen and the surfaces content moves through. That is what integrations unlock, and it is the most interesting thing about this team. When Mural can reach the work happening everywhere else, a canvas stops being a snapshot of one meeting and becomes a live surface for how a team operates: real context pulled in, real decisions pushed back out, nobody retyping a status update or hunting for the current version. A workshop stops ending at the wall of sticky notes and starts ending in tracked, owned, moving work. That is when collaboration gets genuinely effective, and building toward it is the point of everything we do. Underneath all of that, we build the integration platform: the shared frameworks, services, and patterns that let any team at Mural ship a connected experience without starting from scratch. Our mission: to make Mural a natural part of daily work. We measure success by how indispensable Mural becomes inside real customer workflows, not by the number of integrations we ship. YOUR MISSION As a Senior Software Engineer on the Integrated Workflows team, you'll own significant parts of how Mural connects to the outside world. You'll design and build integrations that are reliable, secure, and genuinely used, and you'll turn one-off connector work into integration platform capabilities the rest of the company can build on. This role sits at the intersection of product and platform. You'll work directly against third-party APIs and SDKs with all the ambiguity that entails: shifting contracts, rate limits, auth models, partner review processes. At the same time you'll keep our own abstractions clean and our public API stable for the developers who depend

We look for low-ego individuals who thrive in dynamic and fast-moving environments and move with an experimental mindset — who rapidly test emerging capabilities to discover simpler, more powerful ways to deliver results. At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done. Build the future of data. Join the Snowflake team. Our SI partners play a key role in bringing our customers' data-backed ambitions to life by implementing and harnessing the power of the Snowflake Data Cloud for cutting edge workloads and use cases. Through our partnerships, we enable companies to empower their employees with the data they need when and how they need it to better engage their customers, optimize their operations, and transform their products. The Sr. Partner Development Manager role involves driving and nurturing relationships with our System Integrator (SI) partners. Your primary objective is to strengthen and expand the collaboration between Snowflake and these partners to drive growth. The success of these partnerships are demonstrated by driving growth with our joint customers, delivering key Go-To-Market (GTM) programs, establishing critical executive relationships, enabling partners to grow their Snowflake competency, and delivering customer success. Your success depends on your ability to drive compelling business strategies, GTM motions and relationships within the partner. Strong communication, experienced strategic alliance leadership, and problem-solving skills are vital to excel in this role. KEY RESPONSIBILITIES: ● Strategic Go-to-Market: Work
