SignalsAPI finds new clients for recruitment, staffing and outsourcing agencies. We watch job boards and company career pages across hundreds of sources and tell you which companies started hiring this morning — with the decision-makers to contact already attached.

Around ten agencies have bought and used it over the past year, and roughly a quarter of the demos we run convert to paid. The product is built, live and priced publicly, and anyone can use the signal explorer without an account.

What we don't have is enough of the right agencies seeing it. That's the whole job.

Who we sell to

Recruitment and staffing agencies of 5–100 people — the ones chasing client companies, not candidates. The buyer is the owner, the MD, or whoever owns revenue. Price isn't the obstacle at that size, and neither is the product. Attention is.

What you'll do

• Get agency owners and revenue leads to claim their 10 free signals.
• Build the target list yourself: firmographics, the agencies' own hiring activity, communities, whatever works. SignalsAPI is a good tool for it.
• Run one channel experiment at a time. We rank by impact, confidence and ease, start at the top, and drop what doesn't produce.
• Write the outreach, load the sequences, follow the ones that bite.
• No demo call needed to convert — the sample signals are the demo.

What we're looking for

• Someone who executes. We have around twenty strategy documents on file and not one of them reached a customer.
• Written English good enough that a UK agency owner replies to it.
• Comfortable with AI tools. We use them throughout and don't care how you produce work as long as it lands.
• Available during central European business hours.
• What you've done matters more than where you did it. Send the CV, but the answer to the question below is what we read first.

Nice to have

• You've sold to recruitment or staffing agencies, or worked in one.
• You've built a target list from scratch rather than bought one.

How hiring works

1. Apply and answer the question below. It's the only thing we screen on at this stage.
2. If the answer's interesting, a 15-minute call. One call, no panel, often at short notice.
3. Then a short written plan.
4. Then a paid 14-day trial against a target we agree with you before it starts. Real scope, real money.
5. If the trial works, we talk about the job properly.

What we offer

• Fully remote, hours are yours.
• A product that already converts and public pricing — you're not being asked to validate anything.
• Direct access to the two people who run the company. No layers, no committee.

Traffic Quality Control: Monitor performance metrics via our tracking platform (Alanbase), enforce strict anti-fraud measures, and evaluate traffic quality based on cohort rebill KPIs.

Payout Management: Manage webmaster accounts, review performance, and handle weekly/bi-weekly payout approvals.

Requirements:

Experience: 2+ years of experience as an Affiliate Manager, Publisher AM, or Business Development Manager within an Ad Network (Pop/Native/Banner) or a CPA network.

Network & Contacts: An active portfolio or direct contacts of webmasters in the Streaming, Entertainment, or Torrent niches. You must know how to reach these publishers directly.

Tech-Savviness: Clear understanding of how CPA/CPL models work, tracking platforms (Alanbase/Affise/Scaleo), and S2S postbacks.

Language: Fluent English (written and spoken) is required for dealing with international webmasters.

Mindset: Proactive, result-oriented, and comfortable working with high-volume entertainment traffic.

What We Offer:

High-Converting In-House Offer: A unique monetization model that converts significantly better than standard banner ads, offering publishers much higher eCPM.

Competitive Compensation: Base salary + a rewarding KPI bonus structure based on active subscriptions/rebills.

We are looking for a talented Agentic Full stack Engineer (AI-Native Delivery) with 3+ years of commercial full stack experience, to join an established, revenue-generating B2B platform for the materials industry.

This is not a "write code with AI" role — it's an operate AI agents role: decompose work, fan it out to parallel coding agents, verify adversarially, ship across the stack.

JOB REQUIREMENTS:

Must have:

• 3+ years of commercial fullstack development experience (React + Node.js/TypeScript, or Python)
• Hands-on, practical experience directing multiple AI coding agents in parallel — isolated worktrees/branches, adversarial verification of agent output, spec-driven development, and building reusable AI skills/hooks/commands for recurring workflows 
• Working knowledge of PostgreSQL and basic understanding of cloud infrastructure (Terraform/AWS)
• Ability to work fully autonomously and communicate directly with an English-speaking client team without a manager in between
• English — Upper-Intermediate or higher

Nice to have:

Key Responsibilities:

• Full-stack development across the client's platform — from a React component to a Postgres row-level-security policy to a Terraform module
• Cross-boundary root-cause debugging: auth, pagination, dependency conflicts, integration mismatches
• Turning recurring tasks into reusable AI agent skills, hooks, and commands so the next run is faster
• Proving results with concrete evidence — fixtures, payloads, read-back records — rather than relying on a green CI badge alone

PROJECT

Customer: Established, revenue-generating international platform for the materials industry, backed by a large global industrial distribution group.

Type: B2B SaaS / marketplace platform.

Product: The platform serves as a digital backbone for companies across the materials industry — chemicals, polymers, elastomers, rubber — replacing a patchwork of separate CRMs, ERPs, and spreadsheets with one connected system that turns commercial interactions and physical assets into structured, usable data.

Market: Global materials/chemicals industry, client team based in the US.

Stage: Mature, actively growing platform with an established engineering team (not a from-scratch build).

Project team: 3 developers, 2 QA, 1 DevOps on the delivery side, plus a dynamic client-side team. 

Work schedule: Full-time, full remote

Requirements:

• Strong proficiency in Python.
• Experience designing and developing services and distributed systems.
• Understanding of HTTP, REST APIs, and client-server architecture principles.
• Basic understanding of computer networks and networking protocols.
• Experience integrating with third-party services and APIs.
• Experience working with Docker.
• Proficiency with Git.
• Ability to independently define technical solutions, decompose requirements, and build implementation plans.
• Strong systems thinking and solid engineering practices.

We offer:

• Opportunity to work on cutting-edge defense technologies with real-world impact.
• Professional growth opportunities in a rapidly expanding international company.

Location: Remote | Full-Time Department: Engineering

About Kooltra

Kooltra is a Canadian fintech company building FX infrastructure and cross-border payment technology for banks and financial institutions. With over a decade in market, we're accelerating our US expansion and shifting toward an AI-first development and delivery model.

AI has changed the economics of writing code. The bottleneck is no longer how fast we can build — it's how confidently we can ship. As AI accelerates the volume and velocity of change across our platform, the systems that verify correctness, catch regressions, and keep production observable become the highest-leverage engineering investment we can make. We're hiring an architect-level platform engineer to own that layer end to end.

The Role

You will design, build, and operate the quality gate system that lets Kooltra ship AI-accelerated code with confidence — in a domain where correctness is non-negotiable. Financial infrastructure doesn't get to "move fast and break things." Your job is to make moving fast and not breaking things a structural property of how we deliver software, rather than a matter of individual discipline.

This is a systems-building role, not a QA role. You won't be writing test cases for other people's features — you'll be architecting the automated, layered verification pipeline that every change flows through, from the first property test to production observability.

Key Responsibilities

• Architect a layered quality gate system spanning the full delivery lifecycle: property-based testing, unit and integration testing, contract testing, UI and end-to-end testing, CI/CD pipeline gates, and production observability
• Champion test-driven development as a design discipline across the engineering organization — and evolve what TDD means when AI agents are writing a growing share of the code
• Establish property-based testing as a first-class practice for our financial domain logic, where invariants (balances reconcile, events replay deterministically, money is never created or destroyed) matter more than example-based cases
• Design and own CI/CD pipelines that act as structured, automated gates — every merge and deploy earns its way to production through verification, not review-by-heroics
• Build the UI and end-to-end test infrastructure that keeps critical user journeys verified continuously, with the reliability and speed engineers actually trust
• Define the observability architecture — metrics, traces, structured logs, SLOs, and alerting — that closes the loop from "it passed the pipeline" to "it's behaving correctly in production"
• Make quality gates AI-native: verification systems that validate AI-generated code at the volume and velocity AI development produces, and that AI agents themselves can invoke, interpret, and respond to
• Set the standards, golden paths, and tooling that make the well-tested path the easiest path for every engineer and every AI agent on the platform
• Instrument and report on delivery health — escaped defects, flake rates, lead time, change failure rate, time to recovery — and drive them in the right direction
• Partner with platform, product, and compliance teams to ensure the verification layer supports auditability and our regulatory obligations

Required Qualifications

• Deep experience designing test architecture and delivery systems in enterprise or B2B SaaS environments — you've built quality systems, not just used them
• Hands-on expertise with property-based testing (e.g., jqwik, Kotest property testing, fast-check, Hypothesis) and a clear view of where it beats example-based testing
• A genuine test-driven development practice and the ability to teach, model, and scale it as a design discipline
• Proven experience building and operating UI / end-to-end test infrastructure (e.g., Playwright, Cypress) that stays fast and non-flaky at scale
• Strong CI/CD architecture experience — designing pipelines as products, with staged gates, ephemeral environments, and deployment strategies like canary or progressive rollout
• Production observability expertise: metrics, distributed tracing, structured logging, SLOs, and alerting (e.g., Prometheus, Grafana, OpenTelemetry, Datadog)
• Proficiency in Kotlin and TypeScript, or deep experience on the JVM with the ability to ramp quickly
• Experience with event-driven architectures (Kafka) and how to test them — contract testing, replay testing, verifying eventual consistency
• Hands-on Kubernetes (EKS) and AWS experience
• Genuine enthusiasm for AI-assisted development — and a clear-eyed view of why it makes rigorous automated verification more important, not less
• Excellent communication skills — this role changes how the whole engineering team works, and that requires influence, not just architecture

Nice-to-Have Qualifications

• Fintech, payments, FX, or treasury operations background — you understand why a rounding error is an incident
• Experience building verification systems for AI-generated code, or evaluation harnesses for LLM-based systems
• Mutation testing experience and opinions on measuring test suite effectiveness beyond coverage
• Formal methods exposure (TLA+, model checking) or design-by-contract experience
• SOC 2 or similar compliance framework familiarity — evidence automation, change management controls
• Track record building internal developer platforms, tooling, or golden paths
• Open-source contributions to testing, CI/CD, or observability tooling

Why This Role Matters

Every company adopting AI development is about to learn the same lesson: generation is cheap, verification is everything. The quality gate layer is what converts AI acceleration from risk into advantage — and at Kooltra, it protects systems that move real money for real financial institutions.

If you believe a great test suite is an act of empathy for every engineer who ships after you, that pipelines should be architected like products, and that AI-first delivery is only as strong as the gates it passes through — we'd love to talk.

What is the job

You’ll be the Machine Learning Engineer on a compact, fast-moving team, working directly with the founders. Your mission: design, train, and ship computer-vision models that recognize sports events and generate highlight videos—running both in the cloud and on edge devices.

Responsibilities

• Build & improve CV models – object detection, action recognition, semantic segmentation, tracking, and event classification for multi-camera sports footage.
• Optimize for the edge – convert and quantize models (TFLite/ONNX/RT-Core) so they run in real time on Raspberry Pi 5 and ARM-based phones.
• Own the ML pipeline – data collection, labeling guidelines, experiment tracking (Weights & Biases / MLflow), automated training, and CI/CD to Kubernetes.
• Collaborate cross-functionally – work with backend, video-encoding, and mobile teams to integrate inference results into our NestJS APIs and Flutter/Angular clients.
• Raise the bar – research state-of-the-art techniques, run ablation studies, author technical specs, and mentor future student interns.

Requirements

• Strong Python (3 yrs+) and deep-learning expertise with TensorFlow and/or PyTorch.
• Solid background in computer vision: convolutional nets, attention mechanisms, spatio-temporal models (e.g., I3D, SlowFast).
• Experience deploying models to mobile or edge hardware (TFLite, Core ML, TensorRT, or similar).
• Familiarity with Docker & Kubernetes workflows for scalable training/inference.
• Proven ability to turn research into production code: at least one project or product in the wild (GitHub, app store, or academic publication).
• Comfortable with version control, code reviews, agile tickets, and writing clear documentation.
• Passion for sports—or at least enough curiosity to spot a backhand winner or a slam-dunk replay!

• English—professional level (our dev team is global).

   

Bonus points

• Experience with video encoding pipelines (FFmpeg, HLS, RTMP) or real-time streaming protocols.
• Knowledge of AWS/GCP services for training at scale (SageMaker, Bedrock, Vertex AI).
• Skills in data annotation tooling or active-learning strategies to shrink labeling budgets.
• Background in satellite or aerial image segmentation, sign-language or face-recognition projects (great analogies to sports CV challenges).

• Love for open-source: contributions to CV libraries.

   

Why PUSHIT?

• Ship features that thousands of weekend athletes use every day.
• Work on cutting-edge CV problems with real-time performance constraints.
• Small team ⇒ huge ownership, zero bureaucracy.
• Fully remote
• Competitive salary, early equity, and budget for conferences & GPUs.

This is NOT a traditional developer role.
We’re not looking for someone who writes code all day — we’re looking for someone who leads AI agents that write code for you.

This is not “a regular dev job with an AI assistant”.
This is a role for a person who thinks in systems, prompts, and outcomes, not in endless manual coding.

About us

We are a group of companies with 30+ active projects across travel, fintech, mobile apps, and AI products.
We build products through AI agents, and we’re looking for someone who knows how to work with them effectively.

Tech stack:

• Frontend: Next.js, React Native
• Backend / Infra: Vercel, Firebase, Cloudflare

What you’ll do

• Translate product and technical ideas into clear tasks for AI agents
• Guide AI agents to produce production-ready code
• Review, refine, and improve AI-generated code
• Choose the right models and tools for each task
• Push features all the way to production

In short: you manage an AI-powered dev team that writes code for you.

What we’re looking for

• 1+ year of web development experience
• 3+ months of hands-on work with AI coding tools
• Experience working with AI agents (not just autocomplete)
• Ability to read code and do code reviews
• Solid understanding of frontend, backend, and APIs
• Advanced English

Nice to have

• Built projects mostly or fully using AI
• Know how to optimize AI usage for cost and limits
• Actively follow new models and AI dev tools
• Experience with mobile development

What we offer

• 🏢 Office-based role in Warsaw
• 🤖 Unlimited access to top-tier AI models
• 🎯 Direct collaboration with the CTO — no bureaucracy

How to apply

Please include:

• Examples of projects you built using AI
• Your AI setup: tools you use and how you handle limits and costs
• If you’ve only worked with Cursor — what doesn’t work for you in it?

🚀 If you want to build fast, experiment, and shape how products are created with AI — we’d love to hear from you.
