THE ROLE AND THE TEAM

Senior iOS Developer (Swift/Objective-C) - Remote Position

We're seeking an accomplished Senior iOS Developer to become an integral part of our innovative development team. In this fully remote role, you'll architect, build, and maintain sophisticated iOS applications utilizing Swift and Objective-C. The ideal candidate possesses at least 3 years of hands-on mobile development experience and demonstrates unwavering commitment to crafting exceptional user experiences across Apple's ecosystem.

Key Responsibilities

Our flexible work arrangements, competitive compensation package, and commitment to professional growth make this an exceptional opportunity for passionate iOS developers seeking to advance their careers in mobile technology.

What you'll own

• The product. A brand-new product line, yours to define — what we intercept, what we don't, what the customer-visible surface looks like.
• The technical approach. Instrumentation strategy, deployment shape, programming language — all open. You'll consult with our architects but the direction is yours.
• Implementation, end to end. You'll have the full tooling stack we provide — LLM subscriptions, modern dev infrastructure, the works. Use what makes you fast.
• Methodology. How you build conviction in your detection logic — your call.
• Cross-layer signal. Our existing stack produces threat intelligence at unmatched scale: tens of millions of monitored sites, petabyte-scale malware sample storage, real-time domain and URL reputation, IP-level attack feeds. These are available for you to plug into. Use what helps.

How we'll measure success

The product is held to four numbers: runtime overhead, false positives, false negatives, and customer-escalation volume. They reflect what hosting providers and their customers care about. Hit them well and the product runs inside a meaningful slice of the modern Node.js web.

What we're looking for

An experienced researcher or engineer who can build and iterate on a brand-new product, driving both the research and the development. The hard part of this work is knowing what's malicious, what's vulnerable, and what's just an unusual but legitimate pattern — and being right about it across the long tail of frameworks, libraries, and customer code we'll encounter in production.

Requirements

• Familiarity with the Node.js runtime and the JavaScript ecosystem.
• Strong web application security fundamentals and current knowledge of practical exploitation.
• A working sense of how detection rules behave at scale — what catches attackers without flagging the long tail of legitimate code.
• Ability to start as the PM, architect, lead engineer, and QA for this product. You ask for resources or help when you need them; you don't wait to be told what to do.

• Comfort directing AI coding agents to high-quality output — most of our engineering does this now.
• Prior work on runtime-protection products, application firewalls, or instrumentation tooling.
• Background in malware analysis or incident response.
• Familiarity with managed-hosting environments.
• Public security research, vulnerability disclosures, or detection rulesets you've authored.

What it's not

• Not a scope-and-handoff role — you drive the work and own the outcome.
• Not a "platform team will productize this later" role — you ship to real customer fleets and watch the telemetry quickly.
• Not a spec-and-review role — you are hands-on every day.

Why this matters

Most managed-hosting customers are not developers. They cannot patch their apps. They cannot audit their dependencies. They will keep deploying vulnerable code from AI assistants because that's how modern web apps get built now. The textbook advice — "secure your code, audit your dependencies" — does not apply to them.

If we don't intercept exploits at runtime, nobody will. The numbers you hit on detection, performance, and false positives will materially affect how much of the modern web stays online when the next exploit class drops.

Engineering Manager, Identification Accuracy

The Role

Do you thrive at the intersection of people leadership and applied machine learning? Do you get excited about building and mentoring multidisciplinary teams — ML engineers, data scientists, analysts, and analytics engineers — working together to solve some of the hardest problems in fraud detection?At Fingerprint, the Identification Accuracy team is the engine behind the ML model powering our Identification API — Fingerprint's flagship product. This team is responsible for the accuracy, reliability, and continuous improvement of that model, directly impacting the trust our enterprise customers place in our platform.We are looking for an Engineering Manager to lead this team. In this role, you will foster a culture of high performance and scientific rigor, helping a diverse set of technical contributors grow while driving the roadmap that keeps Fingerprint's identification accuracy best-in-class.

What You'll Do

• Lead and grow the Identification Accuracy team — a multidisciplinary group of ML Engineers, Data Scientists, Analysts, and Analytics Engineers — fostering psychological safety, technical excellence, and a culture of continuous improvement.
• Own the team's roadmap in close partnership with senior engineering leadership and cross-functional stakeholders, driving innovative solutions to identification-specific challenges and continuously raising the bar on model quality.
• Drive model accuracy outcomes by enabling your team to design, train, evaluate, and ship ML models that improve identification accuracy at scale across billions of devices.
• Build bridges across the organization — partnering closely with the Identification Engineering team (who operates the API your models power) as well as Product, and customer-facing teams to translate customer needs into technical priorities.
• Communicate effectively across technical and non-technical audiences, translating model performance and roadmap tradeoffs into language that resonates with business stakeholders and executive leadership.

Requirements

• Minimum of 2 years of experience in a leadership role in a ML or data science team in an agile, fast-paced environment.
• At least 5 years of professional experience in software engineering, machine learning, or a related technical discipline.
• Demonstrated ability to lead technical teams that ship production ML systems — from data pipelines and feature engineering through model training, evaluation, and deployment.
• Proven track record of building and developing high-performing, multidisciplinary teams including engineers, data scientists, and/or analysts.
• Strong communication skills with the ability to translate complex model behavior, data quality issues, and technical tradeoffs to both technical teammates and non-technical stakeholders.
• Demonstrated success driving outcomes in fast-moving, scaling environments where priorities evolve and ambiguity is the norm.

Preferred Qualifications

• Experience managing teams that work with large-scale behavioral or event data in a production setting.
• Familiarity with ML infrastructure and MLOps tooling — experiment tracking (e.g., MLflow), feature stores, model registries, and CI/CD pipelines for ML.
• Background in fraud detection, identity, or trust & safety domains is a plus but not required.
• Hands-on experience with data stack technologies such as dbt or similar analytics engineering tooling.
• Comfort working closely with platform and API engineering teams to understand downstream requirements and latency constraints.
