Job Description
Software Development Engineer II
HighLevel, Inc.
• Design, implement, and iterate on LangGraph workflows that support structured requirement capture, clarification loops, stateful routing, and tool orchestration. • Build reusable workflow components (nodes, validators, schema-enforced outputs, guardrails) and standard patterns for retries, fallbacks, and human-in-the-loop review where appropriate. • Implement robust tool execution patterns (timeouts, error taxonomy, idempotency where needed) and ensure safe, deterministic structured outputs for downstream automation. • Partner with Business Analysts and org leaders during discovery and refinement to clarify goals, constraints, and success metrics; translate requirements into sprint-ready tickets and acceptance criteria. • Build and maintain agent-callable services/APIs for Snowflake retrieval, operational actions (e.g., Slack/workflows), and data enrichment/packaging. • Establish evaluation and observability for agent workflows (golden cases, regression suites, tool mocks; latency/cost/error monitoring) and contribute to pragmatic SLOs. • Contribute to our in-house transcription application through agent adjustments and infrastructure improvements, including transcript ingestion, normalization (timestamps/speaker turns/metadata), storage, and retrieval surfaces for downstream tooling. • Improve reliability of transcription pipelines through queue/worker architectures, retries/backoff, idempotency, and replay tooling. • Implement and iterate on rubric-based call scoring (versioned rubrics, explainable outputs, calibration support) and publish scoring artifacts that are usable for coaching and operational workflows. • Implement streaming considerations where applicable (session handling, backpressure/reconnect patterns) and ensure clean handoffs between capture, transcription, and scoring stages. • Deliver scoped components and workflows with guidance on architecture and design decisions from senior engineers or tech leads.
Job Requirements
- 3–6 years of software engineering experience (backend/services preferred).
- LangGraph experience is required (demonstrated implementation of real workflows).Strong proficiency in Python and/or TypeScript, including API/service design.
- Experience building production services in a compiled, runtime-stable language (e.g., Go) for high-throughput, low-latency workloads (streaming I/O, async workers, and media/transcription pipelines).
- Strong SQL skills; comfort working with warehouse-backed applications (Snowflake preferred).
- Practical experience shipping LLM applications:
- tool/function calling, structured outputs, and schema validation
- retrieval patterns (RAG), routing, and context management
- prompt/version management and evaluation methodologies
- Production engineering fundamentals:
- retries/idempotency, async job patterns, monitoring, and cost controls
- Strong communication and stakeholder partnership skills:
- ability to lead technical discovery conversations
- ability to translate business intent into acceptance criteria and implementation plans
- Botpress or similar agent builders (agent authoring and tool packaging).
- Streaming systems exposure (WebSockets / HTTP2), backpressure + reconnect logic.
- Audio fundamentals (FFmpeg basics, codecs) and experience with transcription providers.
- Serverless/event-driven architectures (Cloudflare Workers/AWS), queues, observability platforms.
- Experience contributing to production systems and growing ownership over time, with mentorship from senior engineers.
Benefits
- None specified
