Technical Support Engineer; L1​/Frontline Support

Job Description The financial industry is growing at a record pace, but our data providers are still stuck in the past — with cumbersome onboarding processes, complicated APIs, slow infrastructure, and expensive licensing costs.

Databento is the market data platform for modern finance. The company provides real-time and historical data across futures, options, and equities through a unified API. By owning the entire market data stack end‑to‑end, Databento is the first platform of its kind to combine the performance and reliability demanded by the world's leading trading firms with a dramatically simpler developer experience. Our team includes alumni of Two Sigma, Citadel Securities, Flow Traders, Tower Research, PDT Partners, SIG, and other top quantitative firms.

This role sits squarely at L1 : you'll be the first point of contact for customer issues, responsible for understanding the problem, resolving common and well‑documented cases, and escalating more complex issues to senior support or engineering with clear reproduction steps and context.

• Act as the first point of contact for customer support inquiries, resolving common customer issues related to API usage, onboarding, authentication, integration, and billing.
• Escalate issues to L2/L3 support or engineering while maintaining accurate ticket status, reproduction steps, and logs.
• Identify recurring questions and contribute improvements to documentation, FAQs, and onboarding materials.
• Write technical content on occasion, including tutorials, how‑to guides, and blog posts that help developers get the most out of our APIs.
• Help manage and grow our online developer communities (Slack, Reddit, etc.) by answering questions and surfacing feedback.

• Prior experience with Databento's API is strongly preferred, as well as familiarity with financial trading and/or market data.
• At least 2 years of experience in technical support, QA, or engineering.
• Working proficiency in Python.
• Experience with troubleshooting tools (Wireshark, tcpdump, ss, nc, telnet, strace, gdb, perf, eBPF, lsof, curl, xxd, jq, SQL) is a plus.
• Experience with observability tools (Grafana, Prometheus, Loki, Sentry) is a plus.
• Strong technical communication skills. Dev Rel experience (e.g. managing Discord communities, creating technical blog posts, podcasts, videos, etc) is a plus.
• Experience at an early‑stage startup is a plus.
