BIMM is booming, so we’re looking for an i OS-first Lead Mobile Developer with hands‑on Swift/Swift UI experience working knowledge of Android/Kotlin, and a strong interest in agentic AI systems that generate and support production‑grade native mobile applications. Local candidates (GTHA) will be asked to join us at BIMM HQ (Distillery District) 2 days per week. We are open to remote candidates across Canada - you will be required to work on EST hours. Who we are BIMM is a Toronto-based agency that lives at the intersection of data, technology, and creativity to provide clients with high‑performing campaigns and digital products that shape connected customer experiences. We’ve helped our clients implement fully integrated CRM customer journeys, built robust digital experiences, and created national loyalty programs with decades of experience in sectors of automotive, financial, telco and retail. We are creative realists, which means our ideas and solutions are grounded in the realities of our clients’ business. We believe big ideas are nothing without big results (and flawless execution); high‑performing agencies deliver high‑performing campaigns, products, and experiences; and the best solutions happen when we collaborate with clients as partners. This is an existing vacancy, not a made‑up role — this one’s already got a desk waiting. Who we’re looking for You design systems that empower autonomous agents to interact, make decisions, and execute tasks seamlessly – building both the application logic and the underlying cloud infrastructure needed to support scalable, dynamic agent operations. You understand how to create agent skills and agent families and how to make them reliable in production through tooling, evals, and guardrails. You have leveraged modern mobile tools and frameworks (Swift/Swift UI, Kotlin, Jetpack Compose, and Kotlin Multiplatform) to architect and deliver i OS and Android applications from the ground up. You are a team player who can fly solo when needed. Although you have the full support of your teammates, you are able to lead the research and solution of complex problems. At the same time, you know when to ask for help and don’t let pride or ego get in the way, because after all, you are part of a team. This role will directly support our client Audi and have the opportunity to shape the development of their digital platform. “Initiative” is your middle name and you don’t give us a chance to chase you. We are on the hunt for people who have an innovative mindset (you still dream of that moonshot project but are currently working on your side‑gig)! Is this you? Responsibilities Core Engineering Lead agentic practice for mobile development.



Lead, mentor, and manage a diverse team of AI engineers across i OS and Android. Build a healthy, collaborative, and inclusive engineering environment. Communicate clearly with technical and non‑technical stakeholders. Ensure agentic generated code is production grade, respects design guidelines and is performant across devices and all supported screen sizes. Work closely with Product, Design, QA, and back‑end teams. Stay current with new mobile capabilities and use them when they add value. AI Engineering Develop agents that can generate high‑quality native applications based on user and business needs. Develop agentic systems that reliably generate production‑grade code using Swift, Swift UI, Kotlin, and related platform tools. Build and maintain automated evaluation pipelines (evals) for agent and skill outputs including LLM‑as‑judge scoring, regression test suites, and golden dataset validation so that prompt and model changes are measurable before they ship. Define strict input/output contracts for MCP tools and agent skills using typed schemas; ensure tools handle edge cases, surface structured errors, and never return ambiguous output that an LLM must interpret. Own the prompt engineering lifecycle for assigned tools and skills version‑controlled prompt templates, parametric input injection, and structured system/user role separation ensuring prompts are testable, reproducible, and free of implicit context drift. Contribute to the team's MCP tooling catalog implement, test, and document MCP‑compatible integrations. Requirements 5+ years of mobile engineering experience, including lead ownership and responsibilities in an agile environment. Experience with i OS development using Swift, i OS SDK, Swift UI. Experience with Kotlin and Android fundamentals. Experience with AI coding agents such as Git Hub Copilot. Familiarity with Jetpack Compose. Understanding of mobile design patterns such as MVVM, MVP, MVI, MVC, or VIPER. Knowledge of i OS provisioning, app lifecycle, and release workflows. Awareness of unit testing and automation frameworks such as XCTest, XCUITest, Mokkery, Espresso, or Robolectric. Experience with accessibility standards, ideally WCAG 2.2 (desirable). Experience with offline storage, threading, and performance tuning.



Experience with CI and CD practices for mobile applications, including Git Hub Actions. Strong understanding of Git‑based version control and Git Hub workflows. Solid knowledge of cloud messaging and push notifications. Ability to translate business requirements into clear technical plans. Solid teamwork, communication, and mentoring skills. Nice to have Experience designing and building agentic workflows – systems that plan, decompose tasks, execute, self‑validate, and iterate on failures. Hands‑on experience with prompt engineering: structured prompts, few‑shot examples, schema enforcement, and output format constraints. Experience with RAG (Retrieval‑Augmented Generation), function calling, and deterministic routing within LLM‑powered systems. Hands‑on experience with LLM structured output patterns: function/tool calling. Familiarity with LLM evaluation approaches: building golden test sets, LLM‑as‑judge pipelines, and prompt regression testing; ability to quantify output quality with measurable metrics rather than vibes. Experience building or consuming agentic workflows multi‑step tool chains, state machine‑based agents, or orchestration frameworks (Lang Graph, Lang Chain, Auto Gen, or custom) with an emphasis on deterministic routing and graceful failure handling. Demonstrated experience defining and rolling out engineering standards at a team or org level (coding conventions, PR workflows, testing mandates, API contracts). Track record of driving AI tool adoption within an engineering team – not just using the tools but creating the onboarding, guidance, and culture around them. Experience with prompt caching, semantic routing, or output memoization strategies to reduce non‑determinism at scale. Ability to instrument LLM calls with structured traces (input, output, latency, token count, tool calls invoked) using frameworks like Lang Smith, Open Telemetry, or custom logging; can define SLOs for agent task success rates. Experience with Kotlin Multiplatform. Familiarity with RESTful APIs to connect to applications to back‑end services. Even if you don’t meet all of the above requirements, we still encourage you to apply! What’s in it for you? Work Life Balance with BIMM days: Spend your birthday any way you’d like, as long as it’s not at the office. Extra day off to enjoy every summer holiday and a week‑long end‑of‑year break. Boo‑yah!
