Detection Engineer

Kyra

ABOUT KYRA Kyra is an enterprise influencer marketing platform working with brands like SharkNinja, Coach, H&M, Ray-Ban, and Converse. Our platform manages the full lifecycle — creator discovery, campaign management, content review, payments, analytics, and AI-powered intelligence across TikTok, Instagram, and YouTube. THE ROLE We’re looking for a senior backend engineer with sharp product judgement. You’ll work alongside our engineering lead on a platform that processes millions of creator data points, runs real-time analytics, and powers AI-driven workflows. This isn’t a “wait for a fully-scoped ticket” role. You’ll take ambiguous direction, make calls, and ship features end-to-end — including deploying them yourself. We have infra already; we need someone who can operate inside it confidently, not someone who wants to rebuild it. WHAT YOU’LL ACTUALLY DO • Build and maintain domain modules in a DDD-style Node.js/TypeScript monorepo. • Take vague product direction, sharpen it into a real spec, and ship a v1 — then iterate. • Design APIs, write docs, and manage database schemas and migrations. • Build features that span our main transactional backend and a separate analytics backend running heavy queries over creator data. • Write services that integrate with TikTok, Instagram, and YouTube APIs. • Work with queue workers for background job processing (media analysis, outreach, data syncing). • Deploy your own services to our cloud infrastructure, write the migrations, watch them go out safely. • Investigate production issues when they touch your code — trace through the observability stack to find the cause. REQUIRED — NON-NEGOTIABLE • 6+ years backend development with Node.js and TypeScript in production. • Product mindset — you’ve shipped features where the brief was a paragraph, not a ticket. You ask why before how, make calls when requirements are vague, and iterate after release. You’ve sat across from non-engineers and left with a sharper problem than you walked in with. • Strong relational database experience — schema design, query optimisation, safe migrations at scale. • Comfortable deploying and operating your own services on a major cloud provider — containers, CI/CD pipelines, the basics of running things in production. You don’t need to be an infra specialist, but you don’t need handholding either. • Queue-based background job processing patterns. • REST API design and documentation. • Git workflow maturity — branching strategies, code review, migration safety. You understand why you don’t run destructive commands on a production migration. STRONGLY PREFERRED • Shipped AI features to production — you know what evals are for, why prompts regress, and why “it worked in testing” isn’t enough. • Columnar / analytics databases for heavy aggregate queries. • In-memory caching and session stores. • DDD or domain-driven design — explicit module boundaries, repositories, services, event-driven patterns. • Production observability — you’ve triaged real issues, not just configured dashboards. • OAuth, OTP, or session-based auth systems in production. NICE TO HAVE • Social media platform APIs (TikTok, Instagram, YouTube). • Search infrastructure for large datasets. • Monorepo tooling and workflows. • Side projects, OSS contributions, or tools you’ve built for yourself that other people now use — signal that you ship for the love of shipping. WHAT THIS PERSON LOOKS LIKE • Holds opinions and changes them fast — you’ll ship the wrong thing sometimes and replace it a week later. That’s the job. • Debugs across boundaries — when a metric shows the wrong number, you can trace it from the frontend component through the API layer down to the database query and figure out where it breaks. • Writes code that doesn’t need babysitting — proper validation, error handling, and patterns other team members can follow. • Communicates proactively — posts in Slack when deploying, writes migration plans before running them, documents API contracts for the frontend team. • Moves fast without breaking things — we deploy to production multiple times a week. You should be comfortable with that cadence while still being careful. TEAM A small, high-output engineering team (~10 people) led by the current engineering lead. Async standups, weekly refinement, ship directly to production. This is a heavy AI-usage environment — AI tooling is woven into how we build, review, and ship. Comfort using it daily is expected. 💟 Support If you have a condition or require an adjustment to our interview process - please let us know so we can make adjustments to support you.

Paddle

WHAT DO WE DO? Paddle offers digital product companies a completely different approach to their payment infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we’re a Merchant of Record for our customers. That means we take away 100% of the pain of payment fragmentation. It’s faster, safer, cheaper, and, above all, way better.   We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North and serve over 5000 software sellers in 245 territories globally. THE ROLE We're looking for an ambitious Engineering Manager to lead our Application Excellence (AppEx) team, one of two teams in our wider Platform group, alongside SRE. AppEx exists to make Paddle's engineers faster and more effective: improving the internal developer experience, establishing golden paths and best practices, building self-serve tooling, and removing operational friction so product teams can focus on their domains. It's a high-leverage role, your work directly changes how every engineer at Paddle builds and ships.   There's a strong appetite for a better developer experience, but the specific path is open: a big part of the job is listening, gathering, and synthesizing feedback, forming a clear diagnosis, and bringing stakeholders with you before you execute. Success depends on alignment as much as delivery.   You'll report to the Director of Engineering who looks after the Platform group, a group that acts as a multiplier for the product teams, taking ownership and providing the tooling that lets them keep adding value while spending as little time as possible on operational concerns.   TECH STACK * Go for our new services * PHP Laravel for our Classic system * Aurora MySQL and PostgreSQL for persistent data storage * Docker in production and local development * AWS ECS Fargate for our runtime * AWS SQS for asynchronous message queues * AWS EventBridge for our event bus * Redis for key/value store * Terraform for resource management * Honeycomb, SLOs and OpenTelemetry for our observability needs     WHAT YOU'LL DO * Lead the team to deliver initiatives to a high standard, from concept and planning through to rollout, working closely with engineers and stakeholders across the organization. * Own developer productivity and internal developer experience as outcomes you lead. * Listen across the organization, synthesize feedback, and build buy-in before committing the team to a direction, then own a clear, well-argued roadmap for sustainable impact. * Coordinate across team boundaries, including with SRE, Security, Principal Engineers, and leadership, influencing without relying on authority. * Manage and coach your engineers, enabling their personal and professional growth and high-impact team performance. * Stay hands-on and technically credible, contributing to code and reviews, while focusing on direction, alignment, and unblocking the team. * Oversee the team's technical decisions and contribute to the Platform group's technical strategy. * Look after the team's shared libraries and tools, maintaining code relied upon by dozens of other services, leading its upkeep and safe rollout to benefit the entire engineering organization. * Drive improvements to group processes, developer experience, and the reliability and scalability of a high-traffic, event-driven system, with autonomy to change what isn't working.     WE'D LOVE TO HEAR FROM YOU IF YOU: * Significant experience as a senior engineer on complex, large-scale, cloud-based systems (Go a plus), including time on Platform or Internal Developer Experience teams * Management experience with several direct reports (2+ years) at at least two places, and a genuine passion for developing people * Excited by and have specific experience building products for internal stakeholders and developers * Excellent at building trust and alignment: gather and synthesise feedback, communicate a clear rationale, and bring people with you before executing; can read a room and adapt * Hold your plans loosely: form strong views from evidence, update them readily with new information, and are comfortable being wrong * Thrive in ambiguity, shaping loosely-defined problems into a clear, sequenced path while still moving at pace * Strong, demonstrable understanding of what makes a high-performing and sustainable engineering team * Proactive and take ownership, while staying self-aware and always pushing to get better     EVERYONE IS WELCOME AT PADDLE At Paddle, we’re committed to removing invisible barriers, both for our customers and within our teams. We recognise and celebrate that every Paddler is unique, and we welcome every individual perspective.   As an inclusive employer, we don’t care where you studied, what you look like, or where you’re from.
