Full job description

Ship & run backend systems that turn messy signals into truth

Boam AI builds managed data solutions that transform messy, unstructured signals from public, private, and proprietary sources into structured, reliable, and always up-to-date intelligence on millions of SMBs and enterprises worldwide. These agentic systems power CRMs, data warehouses, AI products, and mission-critical decisions across the enterprise.

As a Senior Backend Engineer, you will own core parts of our Scala + Python data and agent infrastructure. You will design, build, and scale existing and greenfield systems that keep our data fresh, our APIs fast, and our customers’ workflows moving. This is a role for someone who wants real ownership over hard technical problems, with minimal safety nets and a small, senior team.

What You’ll Do

Design and build resilient backend services and APIs
Own critical data pipelines from ingestion to enrichment to delivery
Prepare our systems for 100x data growth over the next three years
Build reliability and test coverage into the code itself – no separate QA layer
Improve performance, scalability, and observability across our stack
Work closely with data/ML to productize AI-powered agents end to end
Raise the engineering bar through design reviews, pairing, and mentorship
Optimize for real impact, customer outcomes, and fast iteration over theoretical perfection
Use next-gen AI tools to improve code quality and velocity

You Might Be a Fit If...

5+ years building and operating production backend systems
Strong experience with Scala, Python or functional / JVM languages
Comfortable with distributed systems, data modeling, and high-volume pipelines
Enjoy greenfield work: from first principles design to deploy and monitoring
Thrive without heavy process, QA buffers, or endless safeguards
Bias to ship, measure, and refine rather than over-architect
Motivated by solving real user problems, not just abstract puzzles
Excited to work where AI/ML is deeply embedded in the product, not bolted on

Why Boam AI

Join a no-politics, high-trust, low-ego, and high-talent team
Own mission-critical systems used by top-tier enterprise customers
Work directly with founders & Head of Engineering on problems that matter
High autonomy, real impact, and clear ownership from day one
Operate at the intersection of AI, data infrastructure, and enterprise workflows
Top-tier compensation with meaningful equity upside
Help build the platform, patterns, and engineering culture you can be proud of

Our Hiring Process

Our process is fast, structured, and transparent — built to respect your time and surface real mutual fit

1. Intro Call

A short conversation to learn more about you, share context on Boam AI and the role, and answer initial questions

2. Deep Dive

Walk us through past engineering work and how you think about complex, ambiguous backend problems

3. Work Sample

Solve a real Boam-style technical challenge that shows your coding style, system thinking, and execution muscle

4. Founder Conversation

Candid discussion with our founder on ambition, values, ownership, and how you’d grow with us as we scale the platform
