Railtown AI is building a unified platform for modern AI-powered software development. Our products span developer productivity engineering, backend infrastructure for agent and app development, a Python framework for production-ready agents, and structured evaluation workflows for responsible AI deployment.

We're looking for a Head of Developer Relations to help make Railtown AI the default stack for building, observing, and evaluating AI agents. You'll own the developer narrative across Conductr, Railengine, Railtracks, and Agent Evaluations, then turn that story into adoption through technical content, demos, docs, community programs, open source growth, and direct feedback loops with product and engineering.

Good fit if you've spent 5+ years in developer advocacy, DevRel, technical product marketing, or a similar developer-facing role; have scaled a developer platform or technical audience; understand AI tooling, agents, and observability; and can write code, demo live, and communicate clearly with both developers and executives.

Benefits include health coverage, equity, flexible time off, paid parental leave, annual company retreat, and WFH equipment stipend.

We’re building an Agentic AI Security Platform that helps teams secure autonomous AI workflows. We’re looking for a senior engineer to help design and ship core systems across policy enforcement, runtime monitoring, incident workflows, and auditability.

You’ll work across backend and product surfaces: Rust + gRPC services, GraphQL APIs, and TypeScript/React interfaces for security operations. You should be comfortable owning features end-to-end, making pragmatic architecture decisions, and collaborating closely with product/security teams in a small, fast-moving environment.

Strong fit if you have experience with distributed systems, secure-by-default engineering, and production observability. Security product background is a plus, but not required if you’re excited to learn quickly and build in this space.

If this sounds interesting, email us at [hello@lineation.ai] with Resume/CV plus links to your GitHub/LinkedIn and a short note on systems you’ve built.

Opendate is the operating system for live music venues — booking, ticketing, marketing, and settlement, all in one place. We replace the tangle of spreadsheets, holds-and-confirms email chains, and ticketing platforms that independent venues, promoters, and festivals have been duct-taping together for decades. Customers range from 200-cap clubs to multi-day festivals.

We're a Rails shop with real backend problems: multi-tenant ticketing at on-sale scale, financial settlements that have to reconcile to the penny, and integrations with the rest of the music industry's plumbing (Stripe, Dwolla, Seats.io, Twilio, SendGrid). If you like systems where correctness actually matters and the users are people you can go meet at a show, you'll fit in.

Stack: Rails, React/Redux, PostgreSQL, Redis, BigQuery, AWS, GCP, Docker, Terraform. Flutter on mobile. AI-first engineering culture — Cursor, Claude Code, and Copilot are part of the daily workflow, not banned from it.

100% remote within the US (no sponsorship), with optional Indianapolis or Chicago offices if you want them. Looking for 5+ years of senior full-stack experience, comfortable owning projects end-to-end and shipping to production weekly.

Apply: https://www.opendate.io/careers/senior-full-stack-software-e...

We're hiring a junior dev who is genuinely AI-native — your primary tool is Claude Code or Cursor, not your own typing. You'll extend our agentic AI copilot embedded in Architect AI, our portfolio-management web app: text-to-SQL over financial schemas (holdings, transactions, performance), RAG over our internal docs, action tools, deploy and operate the system on Linux + Docker.

Stack: Python/FastAPI, LangGraph, LangSmith, React/TS, SQL Server, Qdrant, Redis, Anthropic + OpenAI + Azure AI.

Required: real SQL chops, ability to read Python and judge AI-generated code, a public project we can look at where you actually used Claude Code / Cursor / Copilot to ship something. 0–2 years professional experience. Recent grads welcome. You'll report directly to the Director of PM who built the system.

Looking for experienced engineers to build and scale infrastructure and data platforms for a Berlin asset management fund. We are betting big on AI to drive investment returns and build the best infrastructure to support our high alpha targets (track record >30% p.a. since inception; https://bitcap.com/en/bit-global-technology-opportunities-ai...).

You'll design large-scale data pipelines, evolve our lakehouse architecture, strengthen data quality and observability, and build infrastructure for AI/LLM workflows (agentic scaffolding, RAG, LLMOps, AI for engineering). We are looking for a hands-on technical leader, that is steering initiatives end-to-end while staying deep in implementation.

We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of ~40 with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.

If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.
