Sr. R&D Engineer

We're looking for a Sr. R&D Engineer to join the Location team and improve the positioning engine behind Pointr's blue dot offering, used in airports, hospitals, and corporate campuses. The engine turns noisy real-world sensor data into a reliable location estimate, indoors and outdoors. It runs primarily on iOS and Android, with the shared C++ core also supporting WebAssembly and backend services. You will take algorithm improvements from research through implementation, validation on real venue data, and release. The work spans probabilistic estimation, sensor fusion, and applied geometry, including the native mobile scanning code that supplies the engine's measurements. You'll join a small, senior team with ownership over technical decisions and a short path from experiments to customer deployments.

Responsibilities

Improve the accuracy, responsiveness, and robustness of Pointr's indoor-outdoor positioning algorithms across a wide range of venue types, devices, and real-world conditions; Research, develop, and evaluate positioning algorithms, spanning classical estimation and machine learning approaches, and measure whether they improve results on real venue data; Research and investigate emerging positioning technologies, including work with development kits, reference hardware, and measurement setups; Build and use offline replay, accuracy regression suites, and simulation tools to measure improvements, and validate on real iOS and Android devices; Develop production code in the shared C++ engine and the native iOS and Android sensor and radio scanning layers, with attention to performance, memory use, thread safety, and test coverage; Turn field issues into reproducible test cases and engine improvements; Use AI coding agents daily for research and development, and take responsibility for reviewing and validating their output; Shape technical decisions through experiments and code review, document the reasoning behind your work, and contribute invention disclosures where warranted

Requirements

6+ years of professional software engineering experience, including performance-sensitive production code; Depth in algorithms and estimation; Strong grounding in probabilistic state estimation and sensor fusion, including recursive Bayesian filtering and particle-based methods; Solid applied mathematics, including linear algebra, probability, numerical methods, and geometry; Experience working with noisy, real-world sensor time series; Daily use of AI coding agents and a basic understanding of how they work; Working knowledge of iOS or Android development; Comfort with native development tools, including build systems, Git, compilers, sanitizers, and profilers, and with cross-platform constraints; Clear technical communication with engineers and non-engineers; Professional fluency in English, both written and spoken

Nice to have

Experience in indoor positioning, GNSS, robotics, SLAM, pedestrian dead reckoning, or RF signal processing; Hands-on experience with Claude Code or OpenAI Codex; other AI coding agents also qualify; Experience building agent tools or integrations; Experience with modern C++, Swift, or Kotlin, or shipping a shared native core in iOS and Android apps; Familiarity with mobile constraints that affect positioning, including background execution, sensor and radio scanning APIs, power budgets, and device differences; Knowledge of ranging and positioning methods used with radio technologies such as BLE, UWB, or Wi-Fi; Experience with computational geometry, geospatial data, or map processing; Wayfinding and graph algorithms; Experience applying machine learning to motion or signal models; Experience building simulation or visualization tools for algorithm development; An MS or PhD in a relevant field, research publications, or equivalent demonstrated depth in positioning, estimation, or spatial algorithms

Benefits

A supportive, kind (no-ego), and smart team; International environment and inclusive culture; Competitive base salary and stock options, based on experience and market; Private supplementary health insurance, in addition to statutory SGK coverage; Paid annual leave under Turkish Labor Law (14 days/year for years 1–5 of service, rising with tenure), plus 5 additional paid days in your first year as a Pointr benefit; Official public holidays as set by the Turkish government; Paid sick leave with a doctor's report, per Turkish Labor Law; 24 weeks of paid maternity leave (state-paid) and up to 6 weeks of paid paternity leave, topped up by Pointr Bilişim above the statutory minimum; Mandatory SGK social security contributions
