We value collaboration, curiosity, and a commitment to solving hard problems. We are growing our team and looking for contributors of all seniorities. We’re looking for a Field Application Engineer who’s wired for AI/ML, fluent in real-world problem-solving, and excited to build with the people actually using what we make. You will collaborate closely with the sales team and enterprise customers, leveraging your deep technical knowledge in AI to drive the adoption of our products and solutions. This is a customer-facing role that requires both technical expertise and excellent communication skills to convey complex technical concepts to non-technical stakeholders. This role is remote based out of North America with preference near one of our main hubs Santa Clara, CA; Boston, MA; or Toronto,ON. We welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting. Who You Are You’ve lived in the AI/ML trenches, whether as a field engineer, a solutions architect, or the one tapped in when things needed to “just work.” You speak both machine and human. Whether it’s a researcher or a skeptical executive, you know how to break things down and bring them to life. You’re fired up about generative models, LLMs, and the edge of what’s possible when software meets purpose-built silicon. Work directly with customers in mee

A World-Changing Company Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more. The Role Backend Software Engineers at Palantir build software at scale to transform how organisations use data. Our Software Engineers are involved throughout the product lifecycle, from idea generation, design, prototyping, and production delivery. You will collaborate closely with technical and non-technical teammates to understand our customers' problems and build products that solve them. We encourage movement across teams to share context, skills, and experience, so you'll learn about many different technologies and aspects of each product. Engineers work autonomously and make decisions independently, within a community that will support and challenge you as you grow and develop, becoming a strong technical contributor and engineering leader. Your day-to-day workflow will vary, adapting to the requirements of our users and the technical challenges that arise. One day, you may find yourself collaborating with other engineers to architect a new system that enables a novel workflow, the next you could be fine-tuning performance to enable low-latency operational outcomes. Our Product Development organisation is made up of small teams of Software Engineers. Each team focuses on a specific aspect of a product and work collaboratively to build cross functional capabilities, streamline user workflows and continuously improve our software's efficiency and reliability.

Company Name: tastytrade Role: Senior Site Reliability Engineer - Linux Systems & Application Observability Location: Chicago, IL (Hybrid, 3 days/week in office) Role Summary Come join tastytrade, part of IG Group, as we build the reliability practice behind the brokerage platform that active options, futures, and equities traders rely on every market day. As our first Senior Site Reliability Engineer, you'll harden the systems behind order execution and market data delivery — designing for fault tolerance, closing gaps in our telemetry, and making sure our HashiCorp Nomad-based service fabric scales cleanly as trading volume grows. You'll work embedded alongside our infrastructure and application engineering teams, contributing directly to our Ruby, Java, and Elixir services. This is a rare opportunity to shape a practice and a culture from day one, on a platform where every order, quote, and position has to be right, because real client capital is on the line. What You'll Do (Job Responsibilities) • Build self-healing, fault-tolerant infrastructure and internal tooling that automates repetitive operational work and reduces toil for Platform and Application teams. • Run gap analysis across our observability stack to find blind spots in telemetry, logging, and alerting coverage, then close them so failures surface before customers feel them. • Own scalability work across our HashiCorp Nomad service fabric: capacity planning, load testing, and identifying architectural bottlenecks before they become incidents. • Extend our observability stack (Prometheus, Honeycomb, OpenTelemetry) with the instrumentation needed to actually see the failure modes above. • Set SLOs and error budgets with multi-window burn-rate alerting for critical brokerage flows, once the fault-tolerance and telemetry foundation is in place. • Mentor engineers across teams to build a culture of site reliability champions so the practice outlives any one person.
