• Performing regular security assessments of Copilot deployments, identifying risks such as prompt injection, model tampering, and data poisoning. • Designing and implementing secure architectures using Identity and Access Management, Conditional Access, and Zero Trust principles. • Developing threat models and executing security testing, including controlled red-team activities. • Building monitoring capabilities, detecting anomalies, and responding to security incidents related to Copilot usage. • Providing advanced (3rd level) support for complex security, performance, and usage issues. • Enabling support teams through documentation, guardrails, training, and definition of escalation processes. • Defining and enforcing security policies, controls, and operational guardrails for Copilot environments. • Assessing security of custom plugins and third-party integrations. • Analyzing data flows and validating encryption and data protection mechanisms.

• Design and develop scalable, distributed, server-side applications and microservices using Go. • Build and optimize mission-critical backend software, with a strong focus on system programming, concurrency, and performance tuning. • Design and implement robust peer-to-peer (P2P) communication systems (P2P experience is mandatory). • Contribute to or build systems using libp2p or similar P2P frameworks. • Ensure cross-platform compatibility and consistent application behavior across environments. • Collaborate within an Agile/Scrum team, contributing to backlog refinement, risk identification, and dependency management. • Produce clean, maintainable, and reusable code, following strong engineering standards. • Optimize backend systems for performance, reliability, security, and fault tolerance. • Establish and enhance backend infrastructure, including deployment pipelines, observability, and monitoring tooling. • Work across multi-cloud environments (AWS, Azure, GCP) and collaborate closely with infrastructure teams. • Participate actively in the full application lifecycle, from design to production operations. • Engage with product and design teams to deeply understand end-user and platform requirements. • Conduct thorough code reviews, mentor other engineers, and raise overall backend engineering quality. • Champion best engineering practices and a culture of high-quality software craftsmanship.

• Translate product requirements into clear, actionable technical plans • Identify key use cases and anticipate edge cases before they become issues • Prioritize and refine requirements to focus on what truly matters • Document and communicate requirements with clarity across teams • Collaborate with product owners and engineers to ensure alignment and completeness • Design and deliver scalable, secure, and high-performing features • Balance functionality, performance, reliability, and maintainability in every solution • Contribute to architecture at the feature, module, and component levels • Debug and resolve issues efficiently using modern tools and techniques • Take ownership of code quality—proactively identifying and fixing defects • Partner with QA to validate features and exceed acceptance criteria • Engage in technical discussions that drive innovation and continuous improvement

• Lead multi-quarter technical initiatives from problem framing through rollout, e.g., trace aggregation APIs, Limitless Tempo, autoscaling cells and customer limits, or query engine improvements. • Own the architecture of core Tempo components: ingestion, storage, query, and metrics generation. Drive design reviews, make sharp trade-offs on performance, cost, and complexity, and document the “why” for the team. • Design APIs for humans and agents. Shape the next generation of Tempo’s interfaces (structured, deterministic, discoverable) so that Act 3 products, LLM-driven assistants, and external integrators can build on Tempo reliably. • Own outcomes against concrete SLOs (P99 write latency, incident recurrence, TCO per ingested GB) and push the team toward Zero Ops through automation, parameterized rollouts, and actionable alerts. • Work closely with PMs and with App Observability, Asserts, Drilldown, and Grafana Assistant teams to understand how Tempo gets consumed and to ship what unblocks them. • Raise the engineering bar through code review, design feedback, pairing on hard problems, and writing that leaves the team smarter than you found it. • Participate in on-call for the services you help build, and be a force multiplier in incident response and post-incident learning. • Tempo is OSS. You will engage the community, review external contributions, and help steer the project in the open.
