Were looking for an AI Software Engineer to own the RL Gym platform end-to-end: from architecting multi-site web environments that simulate real-world attack surfaces, to optimizing our in-house orchestration harness (AgenticVerse) for high-performance delivery into customer training pipelines.
This is a builder role. Youll lead a small team (including a dedicated web environments engineer), operating with high autonomy, moving fast from concept to working prototype to production system. Youll interact directly with customer engineering teams to understand their infrastructure constraints and deliver environments that meet their scale and reliability requirements.
Why this role
This is one of the few roles in the industry where your code directly influences how the next generation of AI models are trained. Youll be at the center of advancing AI safety, building systems that the worlds top labs depend on to make their models more robust. The work is technically deep, the problem space is genuinely novel, and the field is moving faster than any team can keep up with alone. Theres no playbook. Youll write it.
What youll do:
Platform & performance
Own and evolve AgenticVerse, our in-house orchestration harness that provisions and manages RL environments at scale. Focus on performance: low-latency provisioning, high concurrency, minimal overhead per environment instance
Design and build isolated, reproducible web environments using Firecracker microVMs or Docker containers
Architect multi-site scenarios (3-4 interconnected web applications per task) with rich interactions: drag-and-drop, file uploads, authentication flows, LLM-in-the-loop components
Implement deterministic verifiers that evaluate agent behavior with zero ambiguity
Customer delivery
Work directly with engineering teams at leading AI labs to integrate RL Gym environments into their training and evaluation pipelines
Translate customer specs into working environments, iterating rapidly on feedback
Own the technical relationship: SLAs, API contracts, integration architecture

Alice is hiring a Senior Software Developer to lead the development of our internal malware research platform. This is a senior, hands-on role with end-to-end ownership of development and delivery. You'll be the technical authority — setting code-quality standards, making the architecture calls, and mentoring the developer team. What makes this role different is who you build for. Our users are our malware researchers, and they use the tool every day. Your job is to sit beside them, learn how they actually work, surface the heuristics and edge cases they carry in their heads, and build agentic tooling that compounds their productivity. The bar isn't "does it ship" — it's "do the researchers reach for it every day." Success is measured in researcher adoption and time saved, not features merged. Agentic workflows are core to how we build. You should be fluent using them and confident designing systems where agents run in production — with clear judgment about where an agent earns its keep versus where deterministic code or a human-in-the-loop is the right call. What You'll Do Lead development and delivery
* Own technical execution end-to-end: implementation, code review, and release.
* Translate research workflows and feature requests into well-scoped tasks with realistic, risk-aware estimates the team can plan against.
* Manage day-to-day execution: unblock people, sequence work, catch problems early.
* Set and defend the technical bar: review rigor, testing discipline, documentation, architectural consistency. Partner with the researchers — and amplify them
* Embed with malware researchers to understand their workflow and capture the tacit knowledge and edge cases no spec ever wrote down.
* Translate that knowledge into reliable agentic tooling — and know when an agent is confidently wrong before it ever reaches a researcher.
* Spend roughly 5–10% of your time doing actual malware research (with structured onboarding) to stay close to how the tool is used.
* Be willing to tell a researcher when a proposed workflow won't automate well — and explain why. Be the technical authority and mentor
* Make the hard architecture and design trade-off calls.
* Mentor through code review, pairing, and design discussions. Raise the level of everyone around you.
* Dive deep on the critical, difficult features and bug fixes yourself.
* Design agentic workflows into the architecture from the start, and build the evaluations and guardrails that keep them trustworthy.

Were looking for a Founding AI Engineer to build and define the research function at Upriver from zero. This is a rare opportunity to work on some of the hardest unsolved problems in applied AI and agents, with massive ownership, visibility, and room to grow into leadership quickly.

What Youll Do
Lead the AI domain at Upriver: Take ownership of our agent architecture and help define its next phases, standards, and direction.
Solve hard, unsolved problems: Work on challenges in AI agents, reasoning over complex systems, and autonomous decision-making that dont yet have clear playbooks.
Build production AI: Design, implement, evaluate, and deploy AI systems used by real customers.
Be outward-facing: Publish technical blogs, benchmarks, and papers; represent Upriver in the AI and data community.
Move fast with autonomy: Own problems end-to-end with minimal guidance, working directly with founders.
Deliver real customer value end-to-end: take features from idea to production, see them used by customers, and iterate based on real-world impact.

As our QA Engineer, you'll build QA infrastructure that ensures our product meets the highest bar, and youll be the first voice advocating for quality at every stage of development.
About The Role
This is a hands-on, high-impact role. You'll work tightly with developers, product managers, and designers to catch bugs before they ship - and to build the processes and automation that prevent them from appearing in the first place.
You'll design and execute comprehensive test strategies across our platform's most critical workflows, from escalation rules and automation audit configurations to the AI agent behaviors that power our customers' support operations.
What You'll Bring
A quality-first mindset: you see QA not as a gate at the end of the pipeline, but as a discipline embedded in every phase of product development.
The ability to make sharp risk-based decisions - you know when a 2% repro-rate bug in a non-critical feature is a release note vs. a release blocker.
Experience establishing or maturing QA processes in teams that may not have had formal QA before.
Comfort navigating the tension between speed and quality - you can articulate trade-offs to stakeholders and push back on pressure to skip testing when the risk warrants it.
A collaborative, empathetic approach to working with developers - you build trust, not friction.
What You'll Do
Design, maintain, and execute comprehensive test suites - including functional, regression, integration, smoke, performance, and exploratory tests - across our company's AI platform.
Build and expand automated test coverage using Playwright and Typescript, integrated into our CI/CD pipeline.
Collaborate with developers throughout the SDLC: participate in sprint planning, review requirements for testability, join design reviews, and validate acceptance criteria before development begins.
Own the QA process for key product areas, including escalation configurations, automation audit rules (email patterns, subject lines, message keywords), and AI agent behavior customization.
Investigate, document, and triage bugs with detailed, reproducible reports - and advocate for the right balance between blocking a release and shipping with known issues.
Debug web application issues using browser DevTools, network analysis tools, and API testing utilities.
Champion a testing culture across the engineering organization - quality is everyone's responsibility, and you help make that real through process, tooling, and collaboration.
Proactively identify subtle bug classes - race conditions, off-by-one errors, timezone issues, Unicode handling, caching inconsistencies - and build test strategies specifically targeting them.
Evaluate and recommend improvements to QA tooling, processes, and infrastructure as the team and product scale.
