Original job description

Citian is a fast growing, venture backed SaaS technology company based in Washington, DC. Our software solutions revolutionize how our transportation and infrastructure systems – roads, rail, transit, bicycle, pedestrian – operate.

Our tech solutions:

Reduce traffic fatalities
Enhance pedestrian accessibility
Empower system operators to save time & money

You’ll work with some of the brightest minds in the software and transportation industries. Our engineers and data scientists apply the latest in emerging tech, Artificial Intelligence, and Machine Learning to build smarter, more advanced tools for our diverse client base. We work with clients across the United States, with global ambitions in the years ahead.

Who You Are:

You're a product-minded software engineer who turns customer problems into reliable AI-enabled capabilities. You've built and shipped production LLM features, and you know the difference between a convincing demo and a dependable product. You work across the stack, prototype quickly, validate both the value and the correctness of what you build, and turn the experiments that work into production software. You know when AI is the right approach and when conventional software is better. You're comfortable with ambiguous requirements and work with engineering, data science and customer-facing teams to find where AI creates real value for transportation agencies.

Expected Duties:

Work with product, design, Customer Success and data science to understand agency problems, and help find and validate where AI adds value and where it doesn't.
Design, build and ship AI-enabled capabilities within our products, end to end, from data access to the application.
Fit model-based features into our existing software and data architecture without building unnecessary AI infrastructure, and record the key design decisions.
Design and maintain evaluations for AI features, including correctness, grounding, authorization, appropriate abstention and regression detection. Establish practical release criteria and use production feedback to improve quality.
Make AI-generated results traceable to their underlying data, queries and assumptions.
Enforce customer isolation and each user's own permissions, including when tools retrieve or query data, and guard against prompt injection.
Own features in production: latency, cost, reliability, monitoring, failure modes and incident response.
Choose the right technique for each problem (prompting, tool use, retrieval, text-to-SQL, fine-tuning or no AI at all), weighing accuracy, cost, speed and time to market.

Required Skills & Experience:

Bachelor's degree in Computer Science, Data Science, or a related field
5+ years building production software, including shipped LLM features used by customers
Demonstrated ability to take an ambiguous product problem through technical discovery, implementation, evaluation and production delivery
Has designed and run evaluations for LLM output: test sets, correctness and grounding measures, regression gates, and catching wrong answers before customers do
Full-stack product skills: Python or TypeScript back ends, SQL and relational databases (PostgreSQL), APIs, and enough front end to ship a feature end to end
Production practices: code review, CI/CD, testing, monitoring and cost tracking
Uses AI coding tools and agents effectively in daily engineering work, including implementation, testing and investigation, while independently validating their output
Clear written English and solid overlap with US Eastern hours

Preferred Qualifications:

Snowflake, AWS (including Bedrock), or LLMs over analytical or structured data
Geospatial, transportation, public-sector or other complex, high-stakes data
Security and compliance work around customer data (multi-tenant isolation, authorization, audit, SOC 2)
Has led a feature end to end across teams

Salary Range: $150,000 - 200,000

Your Citian Advantage:

Competitive salary and benefits package including medical, dental, and vision insurance and generous PTO.
401(k) company match and monthly commuter transportation benefit
On-site gym and free snacks in the office
High-growth potential and opportunities for advancement within a fast growing, venture-backed SaaS startup!

Let's build smarter cities together! Learn more about Citian here: www.citian.co
