Headquarters: Tampa, Florida URL: https://koast.ai Head of Product | Contract, 20 hrs/week to start, growing into full-time | Remote (US overlapping hours) | Reports to the CEO The short version Koast is the AI operating layer for teams that run Meta ads at volume. Agencies, in-house media buying teams, and enterprise buyers managing 10+ ad accounts and launching 50+ ads a week use Koast to launch faster, automate optimizations off real attribution data, and see every account from one hub. The Koast Agent is the next layer: an AI that reads the account, spots what matters, and acts inside guardrails. We are a small team shipping fast. The product is live, customers are paying, a Whop partnership just onboarded a wave of new users, and the Agent build is underway. What we do not have is one person who owns the product end to end: what gets built, why, in what order, and whether it actually landed. That is this role. It starts at 20 hours a week on contract. If you are the right person, it becomes the full-time product seat at Koast. What you will own Discovery that finds the real problem. You will sit in on enterprise sales calls and onboarding sessions, run discovery with agencies and media buying teams, and figure out what they are actually trying to get done versus what they say they want. Every feature request gets mapped to a job: launching smoother, getting their team in, getting tasks done, keeping users active and growing spend inside Koast. If it does not serve a job, it does not get built. Specs that engineering can execute without a meeting. We run a lean engineering team plus an AI-assisted dev pipeline. That only works when the ticket is unambiguous. You will write PRDs and Shortcut tickets that define the behavior, the edge cases, the data dependencies (Meta API limits, Hyros and Cometly attribution feeds, Whop account provisioning), and the acceptance criteria. If an engineer or an agent has to guess, the spec was not done. The queue, and what is missi

Over 25.5 million people across the world use our apps — Muscle Booster, Yoga-Go, and WalkFit — to build healthier habits, move more, and feel better every day. Every subscription represents a real person making a real change in their life, and we take that seriously. With 500+ people across hubs in Cyprus, Ukraine, Poland, Spain, and the UK , we combine the scale of a market leader and the drive of a team that's just getting started. What We're Looking For As a Senior Data Engineer , you will play a crucial role in building and maintaining the foundation of our data ecosystem. You’ll work alongside data engineers, analysts, and product teams to create robust, scalable, and high-performance data pipelines and models. Your work will directly impact how we deliver insights, power product features, and enable data-driven decision-making across the company.

ExpelRemote1w ago
Headquarters: Remote Are you a detection engineer who wants to bring real depth of expertise into a new and growing function and use it to deliver security excellence to customers? Expel's professional services practice is just getting started, and we're looking for the technical expert who'll deliver the work that gets customers ready to thrive under our co-managed SIEM model. You'll bring hands-on skill to a team that's finding its stride, help it grow, and have a real runway to grow into a lead yourself. Here's the work. Customers come to us with SIEMs that should be surfacing threats but are instead consuming their teams: ingestion costs climbing year over year, engineers buried in alert noise and broken pipelines, and detection blind spots leaving real gaps. You're the engineer who turns that around: authoring and tuning detection content that satisfies real security use cases, closing coverage gaps, migrating detection logic off legacy platforms, and helping optimize what customers ingest and pay for, so their SIEM becomes a force multiplier again, not a management burden. And because this function evolves right alongside our customers and the market, the work won't stand still. Expect it to grow into deeper integrations, automated and AI-assisted tooling, and security strategies our customers need next. What Expel can do for you Give you a ground-floor seat in a new professional services function, where your expertise directly shapes the quality of what we deliver to customers Provide real runway for professional development as the function grows Put you on complex, high-stakes detection and SIEM problems across a wide range of customer environments Let you work across leading SIEM platforms, including Splunk, Microsoft Sentinel, and CrowdStrike NG SIEM, plus emerging AI-assisted tooling Give you visibility and partnership across the organization, including Sales, Detection Engineering, our SOC, and Customer Success Accelerate your career by letting you own m

CircleCIRemote1w ago
Headquarters: Remote, Ontario, Canada About CircleCI Engineering CI/CD has been solved. Now it's being reinvented. AI agents don't just run pipelines. They write code, trigger builds, interpret failures, and propose fixes. The interfaces that developers use to understand and trust that work don't exist yet. We're building them. At CircleCI, our guiding principles aren't posters on a wall. We learn fast: we run experiments, accept failure, and scale what works. We think like the customer: every decision connects back to the developer sitting in front of a failing build at 2 am. We own the outcome: not just our slice of it, but the whole thing. If that's how you already work, you'll fit here. Team-Agnostic Placement We don't hire for a team. We hire for CircleCI. Where you land depends on where your strengths create the most leverage, and we figure that out together. You might own the CI pipeline experience, deploy and release tooling, notification infrastructure, monetization flows, AI agent surfaces, or the foundational web platform. The through line across all of it is the same: full-stack ownership, a high bar for craft, and work that directly shapes how tens of thousands of developers experience CircleCI every day. What You'll Do Build AI-natively. AI is how we work. It's not a productivity layer on top of engineering, but the default starting point for how problems get approached and solved. Set technical direction. You define the approach others build from. When the problem is complex or the answer isn't obvious, you're the person who leads the design discussion, writes the ADR, and makes the call. Invent new interfaces. Software delivery is being reinvented. Pipelines run autonomously, generate fixes, and surface results that need human judgment. The tools developers use to understand, trust, and act on that work don't exist yet. You'll define what they look like and establish the patterns the team builds on. Own the full stack. Build features end-to-end in Go

What You’ll Do: Work cross-functionally with product, design, and other engineering counterparts to execute on product and business strategy and build novel products and features that our users will love. Contribute to the full development cycle: technical design, development, test, experimentation, analysis, and launch. You’ll be reviewing code and design docs, giving feedback on product specs and mocks. Contribute meaningfully to team strategy. We give everyone a seat at the table and encourage active participation in planning for the future. Don’t just come along for the ride. Participate with a team of thoughtful, fast-moving, and motivated engineers. Contribute to standards that improve developer workflows, and recommend best practices. Move fast while balancing quality. We can’t afford extensive processes, and we also can’t afford show-stopping bugs. We need someone who can balance speed with quality while quickly building brand-new products. Continuously learn and improve your technical and non-technical abilities. Who You Might Be: BS

Headquarters: Americas Remote About Customer.io Over 9,000 companies — from scrappy startups to global brands — use our platform to send billions of emails, push notifications, in-app messages, and SMS every day. Customer.io powers automated communication that people actually want to receive. We help teams send smarter, more relevant messages using real-time behavioral data. About the role Hi, my name is Nick Guardino, Senior Director of Marketing Ops at Customer.io , and I'm looking for a GTM AI Engineer to help take our AI agents from scrappy prototypes to production-grade systems our GTM teams can depend on. Over the last 3.5 months, our GTM AI team has built 11 agents now running in production, serving 120 active users and roughly 25,000 tool calls a day — all through custom CLIs that work, but weren't built to scale. We believe businesses can run leaner and go further when they deploy AI agents well, and we're figuring out that motion in real time. This role owns the scale and reliability layer so the rest of the team can keep building. What we value Craft over quick wins — energized by making things robust, not just making them work. A point of view — we want someone who asks "why did you build it that way?" and has a specific answer for what to do instead. Comfortable being wrong — you try things fast, and you course-correct just as fast. AI-native by default — you'd rather direct Claude to write and QA code than write it by hand. What you'll do Alpha-to-production ownership — take newly built agents from working v1 to production-ready: write evals, harden prompts and tool definitions, and refactor prototype scaffolding into clean, production-quality code. Observability & stability — instrument tracing, logging, and monitoring across the agent fleet so we catch regressions before our 120+ GTM users do. Deployment & infrastructure — stand up and maintain the pipelines that get agents into users' hands without surprises, owning environment parity and release hy
