Job summary

Positron Corporation seeks an Engineering Manager to lead Production Platform and Orchestration, owning API fidelity, tool calling, and new-model readiness. You will hire, mentor, and scale a high-impact team while shaping strategy across fleet, deployment, and observability.

You will collaborate with hardware, data centers and customer-facing teams to drive reliability and performance as the fleet expands across multiple platforms.

Qualifications

• Demonstrated success managing and growing engineering teams responsible for LLM inference, model serving, ML systems, or a closely related domain.
• Systems depth in C++ and working proficiency in Python; comfort reviewing performance- and correctness- critical code.
• A record of turning ambiguous product demands into a coherent roadmap, explicit ownership, and measurable engineering outcomes.
• Ability to recruit, coach, and retain engineers across experience levels while maintaining a high technical bar.
• Clear written and verbal communication, sound prioritization, and the ability to make tradeoffs visible to technical and executive stakeholders.
• A hands-on leadership style: close enough to architecture and code to ask the right questions without becoming the team’s bottleneck.

Responsibilities

• Lead, coach, and grow a team of engineers spanning API serving, tokenization, structured generation, and model integration.
• Establish a clear technical and organizational roadmap for the serving layer: API surface, chat templates, tool calling, reasoning, budgets, and new-model support.
• Ensure API fidelity: OpenAI-compatible behavior, streaming, usage accounting, and error handling that customers and their tooling can rely on.
• Lead reasoning-model support and request budgets, including reasoning formats, reasoning-effort controls, token limits, and per-request accounting.
• Partner with Compiler/Executor on speculative decoding: draft-model integration, request-side plumbing, acceptance metrics, and policies for when speculation pays off.
• Lead the plan for vision-language model (VLM) support and SGLang interoperability, deciding what to adopt, what to build, and how it fits Positron's engine.
• Keep serving-layer overhead off the critical path for time-to-first-token and streaming latency.
• Keep the API layer independent of hardware topology as Positron adds platforms that run inference across multiple hosts.
• Work with Production Platform and Orchestration to define clear ownership of the shared host-level load-balancing layer, including where request policies and protections live.
• Build release gates (API conformance tests, tool-call and reasoning evals, regression suites) so new models and features ship with confidence.
• Collaborate with Production Platform and Orchestration to turn new serving capabilities into supportable production endpoints.
• Translate customer and business priorities into sequenced engineering work while protecting the team from reactive, unstructured requests.
• Hire thoughtfully, develop emerging leaders, and create ownership boundaries that remain effective as the organization scales.
