Role
Who you are
- Love for writing clean, performant code and a track record of building production-grade backend systems
- Strong proficiency in Python or Go and TypeScript (Node) for building scalable web services
- Experience with agentic patterns, including function calling, tool use (MCP), and orchestrating multi-step LLM workflows
- Ability to write and optimize complex SQL queries and data access patterns to ensure LLMs are grounded in real-time data without sacrificing latency or system performance
- Deep understanding of OpenAI/Anthropic/Gemini APIs, prompt engineering, and managing complex conversation state/context
- Proven ability to build seamless API integrations with LLMs, managing the bridge between unstructured model outputs and structured internal services through robust error handling and schema validation
- Strong database confidence with PostgreSQL, OLAP Databases, and Redis. You know how to use the right tool for the job to ensure fast retrieval
- Experience with microservice-oriented architecture and designing for scale (we handle 1B+ images daily)
- Proficient with AWS services, Kubernetes (EKS), Docker, and CI/CD build tooling
- You thrive in "zero-to-one" environments, taking ambiguous problems and turning them into technical roadmaps
- Experience with LLM evaluation (LangSmith/Langfuse), vector search/RAG, or infrastructure-as-code (Terraform)
What the job involves
- We're hiring a Senior Backend Engineer to lead the architectural evolution of Nightshift, a conversational AI assistant that helps investigators surface critical evidence and close cases faster
- This isn't just about wrapping an LLM; it’s about building the "brains" of an investigative agent
- You will design the orchestration backend that manages complex LLM interactions, develop high-performance integration pipelines connecting our AI to Flock's massive data platform, and build the agentic framework that allows Nightshift to "act" on behalf of investigators
- This is a ground-floor opportunity to solve the reliability and scaling challenges of deploying AI in high-stakes, real-time investigative workflows
- You’ll partner with ML engineers on agentic workflows and platform teams to design robust APIs that ground AI in truth, ensuring our system remains performant as we process billions of data points daily
- The First 30 Days:
- Familiarize yourself with Flock’s investigative workflows and the massive data pipelines that power our platform
- Pair with ML (agentic systems), Data Engineering (investigative datasets), and Platform teams to understand the existing API landscape
- Complete your first push to production. Pick up initial sprint tickets focused on API integrations, backend bug fixes, or performance tuning for LLM streaming
- The First 60 Days:
- Implement the backend orchestration layer for LLM tool calling and multi-step reasoning
- Design and build the "connectors" that allow Night Shift to securely and efficiently query Flock’s core data services
- Stand up robust tracing and logging for the AI system to monitor agentic decision-making and reliability
- Own end-to-end backend features that connect the LLM to our internal APIs, ensuring low-latency responses for investigators
- 90 Days & Beyond:
- Lead the development of a core Nightshift capability—like automated lead generation or cross-camera correlation—that demonstrably closes cases faster
- Establish best practices for testing and deploying AI agents within a microservices environment
- Influence the product direction by identifying how new backend capabilities or AI breakthroughs can solve untapped investigator pain points
Application process
- We want our interview process to be a true reflection of our culture: transparent and collaborative. Throughout the interview process, your recruiter will guide you through the next steps and ensure you feel prepared every step of the way
Our take
Public vehicle surveillance provides valuable insights to emergency services for the prevention of crime, but bringing information together to create leads is difficult. There's no standardised system for inter-city vehicle surveillance, and this makes it difficult for communities and law enforcement services to work together.
Flock Safety provides surveillance equipment that aims to improve the abilities of law enforcement and homeowner associations to communicate data with each other. The company focuses on vehicle surveillance, innovating on existing technology by using machine learning to categorise vehicles by color, license plate, state, and other data points.
Whilst automated surveillance equipment is used daily within federal police forces, Flock Safety builds technology systems that provide a means for smaller law enforcement agencies to quantify and share surveillance data easily. It's caught on too, with a funding round of $275 million awarded in 2025 that will be used to expand its manufacturing capabilities. lock Safety, a U.S. startup developing surveillance technology, has raised $275 million in new funding led by Andreessen Horowitz, as it invests in a manufacturing facility and expands into drone products, the company told Reuters. funding behind it, This data can then be automatically processed to help develop leads, a time-consuming process that would usually have to be completed manually.
