Middle/Senior Frontend Developer (Angular) at Fleet Chaser

About Fleet Chaser

Fleet Chaser is a U.S. based B2B SaaS company helping construction, logistics, and service fleets (10+ vehicles) run smoother. Our platform brings everything into one place – real-time vehicle location and status, service data, tasks, time tracking, and reports. We're building products that make fleet managers' and field employees' lives easier every single day.

 Now we're looking for a Mid/Senior Frontend Developer to join our team and help us take our Console web app to the next level. We care less about the title on your CV and more about the fire in your eyes, your initiative, and your ability to ship.

 What you'll do

The Console is our core product for dispatchers and fleet managers. You'll own its frontend — building new features, improving existing modules, and keeping the platform fast and stable as we grow.

- Develop and maintain our Console web app using Angular & TypeScript.

- Build new features end-to-end — from Figma to production.

- Improve existing modules — performance, UX polish, and edge cases that come from real customers.

- Integrate REST APIs, WebSocket events, and third-party services.

- Collaborate with designers, backend developers, and product managers.

- Write clean, scalable, and maintainable code with proper testing.

- Propose ideas, improve approaches, and help us build not just tasks, but a great product.

 Requirements

- 4+ years of commercial Angular experience.

- Strong TypeScript (generics, type guards, RxJS Observables).

- Modern Angular: Signals, Standalone components, complex state management (NgRx Store / Services).

- Solid grasp of frontend fundamentals — Observables, Singleton, dependency injection — and the ability to explain *when* to use what, in plain words.

- Solid understanding of HTTP/REST, WebSocket, JWT auth, EventSource (Server-Sent Events).

- Reactive forms, complex tables, filtering/sorting, virtual scroll.

- Experience with maps (Google Maps / Mapbox / Leaflet). We rely heavily on Google Maps and it's growing across the product — we don't want a single person owning all of it.

- Experience working with Figma — read specs, implement pixel-perfect, give feedback to designers.

- Strong code review culture (well-described PRs, responsive to comments).

- Mindful use of AI tools. You own everything you push. Review what the model gives you before it lands in main — "the AI did it" is not an answer.

- English level: B1+.

 What matters beyond skills

- Initiative — bring ideas, propose improvements, don't wait for someone to hand you the next task. We have settled patterns and we want them challenged.

- Ownership — take a spec, drive it to production without micromanagement. You're responsible for the code you push, including the AI-generated parts.

- Discipline — review your own diffs before they leave your machine. Every commit. Every PR.

- Finish what you start — no features sitting at 80% for weeks.

- Honesty — when something breaks or slips, name it. We all make mistakes; we deal with them faster when nobody hides behind tooling.

- Concrete communication — short updates, on-point questions, no fluff. Remember what you worked on yesterday and be ready to talk about it.

- Pragmatism — balance quality and deadlines, no overengineering.

- Receptive to feedback — engage with code review without defensiveness.

- Product mindset — dive deep into the product, understand the *why*, not just the *what*.

 Nice to have

- Experience building or maintaining a design system — component libraries, tokens, scalable theming. This is one of the areas where a strong hire would meaningfully level us up.

- Real-time UI experience (live tracking, WebSocket events, Server-Sent Events).

- B2B SaaS / fleet / logistics domain knowledge.

- Performance optimization for large list views (1000+ rows).

 Why Fleet Chaser

- Work on a real product with real users — thousands of active fleet employees and managers in the U.S. market.

- Small, focused team — your work has direct impact.

- Culture of value delivery, analytics, and growth.

- Remote-friendly, flexible work setup.

- Direct contact with PM and Team lead — no layers between you and decisions.

 Hiring process

1. Screening call with Vlad (PM) — up to 1 hour.

2. Technical interview with Vitaly (Owner) + Nikita (Senior Console FE) — up to 1 hour.

3. Probation period — up to 3 months on real product tasks, mutual evaluation.

About the Mission

We are building an AI-driven payments ecosystem designed to transform a $50B industry still dominated by slow, legacy processors. As Head of ISO, your mission is to architect, lead, and scale our merchant acquisition engine. You will set the commercial direction, build high-performing processes, and drive measurable revenue impact - first through hands-on execution, and then by leading automated, scalable systems you help define.

What You’ll Do

• Architect and launch the ISO function end-to-end: strategy, operating model, tooling, and execution;
• Own the full merchant pipeline: prospecting → qualification → underwriting coordination → negotiation → closing → onboarding/activation;
• Define and refine commercial fundamentals: pricing strategy, merchant segmentation, and offer frameworks aligned with risk and margins;
• Build scalable operational workflows and enforce portfolio health ratios (chargebacks, fraud, dispute rates), in close coordination with Risk/Compliance and Processing partners;
• Map and manage banking/acquiring coverage (“bank mapping”) and route merchants to the right partners based on vertical, geography, and risk profile;
• Build and maintain relationships with PSPs, acquirers, and key commercial partners to unlock approvals, improve conversion, and expand capacity;
• Standardize playbooks, scripts, and governance, ensuring every opportunity is tracked, advanced, and optimized for conversion;
• Drive process automation with Product & Engineering: convert manual tasks into AI-powered workflows across outreach, qualification, CRM hygiene, and reporting;
• Recruit, develop, and lead the ISO team, creating a high-performance culture centered on consistency, accountability, and results;
• Deliver advanced reporting, forecasting, and KPIs to leadership; act as a senior commercial partner shaping revenue strategy and growth targets.

You’re a Strong Fit If

• You’ve built or scaled an ISO/merchant services function and know what “from zero to repeatable engine” looks like;
• You have strong domain understanding of underwriting, processing economics, risk, and portfolio management;
• You are equally comfortable leading and executing - entrepreneurial, hands-on, and operationally rigorous;
• You thrive in fast-changing environments, build structure quickly, and drive predictable outcomes at scale;
• You operate with urgency, handle high-stakes initiatives, and take full ownership of results.

Required Skills

• Extensive experience in ISO / merchant services / payment processing, ideally with proven ISO build/launch exposure;
• Track record of closing complex merchant deals and managing merchant portfolios with strong risk awareness;
• Ability to define pricing/segmentation and align commercial execution with underwriting and partner constraints;
• Strong operational discipline: scalable workflows, CRM governance, forecasting, and KPI-driven management;
• Excellent communication, negotiation, and relationship management; leadership maturity and resilience.

Nice-to-Have

• Experience in fintech, SaaS, or payment technology environments;
• Familiarity with CRM systems, outbound engines, or automation workflows;
• Background in building or managing distributed commercial teams.

Why This Role Matters

• Shape the commercial backbone of a fast-moving, high-impact payments ecosystem.
• Direct access to founders and leadership, with zero bureaucracy and high decision velocity.
• Full ownership and autonomy: you build the system, the team, and the results from scratch.
• Competitive compensation with significant performance-based upside.
• A rare opportunity to lead innovation in one of the most lucrative and underserved segments of fintech.
