Role Description

We're hiring a Software Engineer to build Night Shift, a conversational AI assistant that helps investigators surface critical evidence and close cases faster. You'll:

• Design and implement the conversational interface.
• Build the orchestration backend that manages LLM interactions and tool calling.
• Develop integration pipelines connecting our AI to Flock's existing data platform and APIs.
• Shape chat experiences with complex context management.
• Partner with platform teams to design new APIs or leverage existing ones.
• Solve reliability challenges of deploying AI in high-stakes investigative workflows.
• Collaborate closely with ML engineers on prompt engineering and agentic workflows.
• Maintain a strong point of view on what makes a great user experience.

Qualifications

• Love for coding and continuous learning, especially in the rapidly evolving LLM space.
• Resourceful problem-solver mindset: excel in ambiguous situations and take initiative to define product direction.
• Strong TypeScript / Node / Express skills for web services and API design (REST, SSE, WebSockets for streaming).
• Modern web framework expertise (React / TypeScript preferred), particularly for conversational UI and chat interfaces.
• Hands-on LLM experience: OpenAI/Anthropic/Gemini APIs, prompt engineering, streaming responses, and conversation context management.
• Familiarity with agentic patterns: function calling, tool use (MCP), and orchestrating multi-step workflows.
• API integration skills: consume existing APIs or design new ones to ground AI in investigative data.
• Database confidence: PostgreSQL and sophisticated SQL for data retrieval.
• Cloud infrastructure basics: Docker, Kubernetes (Helm), AWS services (S3, SQS, API Gateway).
• Product-minded: translate user feedback into technical requirements and make pragmatic tradeoffs.

Requirements

• Bonus points for LLM evaluation tools (LangSmith, Langfuse), vector search/RAG, microservices architecture, or Terraform.

Benefits

• Flexible PTO: We seriously mean it, plus 11 company holidays.
• Fully-paid health benefits plan for employees: including Medical, Dental, and Vision and an HSA match.
• Family Leave: All employees receive 12 weeks of 100% paid parental leave. Birthing parents are eligible for an additional 6-8 weeks of physical recovery time.
• Fertility & Family Benefits: We have partnered with Maven, a complete digital health benefit for starting and raising a family. Flock will provide a $50,000-lifetime maximum benefit related to eligible adoption, surrogacy, or fertility expenses.
• Spring Health: Offers a variety of mental health benefits, including therapy, coaching, medication management, and digital tools, all tailored to each individual's needs.
• Caregiver Support: We have partnered with Cariloop to provide our employees with caregiver support.
• Carta Tax Advisor: Employees receive 1:1 sessions with Equity Tax Advisors who can address individual grants, model tax scenarios, and answer general questions.
• ERGs: We want all employees to thrive and feel like they belong at Flock. We offer three ERGs today - Women of Flock, Flock Proud, and Melanin Motion.
• WFH Stipend: $150 per month to cover the costs of working from home.
