What is an engineer?

Engineers design, build, and maintain the functional aspects of a product, structure, or system for their specific engineering industry. Their specific job description relates to all of the detailed tasks, responsibilities, skills, and education requirements that a company or organization requires for their engineering specialty. For example, electrical engineers develop, monitor, and test electrical systems. Civil engineers design, construct, and maintain large infrastructure projects, such as highways, bridges, and airports. Many engineers begin their career with an internship or apprenticeship while they are still in school, and then acquire an entry-level position. As they learn more about the industry, engineers are given their own projects and more responsibility.

What are the key skills and qualifications needed to thrive as an engineer?

To thrive as an Engineer, you need a solid background in mathematics, problem-solving, and engineering principles, typically supported by a relevant bachelor’s degree. Familiarity with industry-specific software such as CAD tools, simulation platforms, and, in some fields, certifications like FE or PE is often required. Strong communication, teamwork, and critical thinking skills set exceptional engineers apart. These abilities ensure effective project delivery, innovative solutions, and smooth collaboration in technical environments.

What does an engineer do?

An engineer applies principles of science and mathematics to develop solutions for technical problems. They design, build, and test products, systems, or structures while considering efficiency, safety, and cost. Engineers can work in a variety of fields such as civil, mechanical, electrical, and software engineering, each with its own specialized focus. Their work often involves teamwork, problem-solving, and the use of advanced technology.

How do engineers typically collaborate with other departments during a project?

Engineers often work closely with professionals from various departments such as product management, design, and quality assurance to ensure project requirements are met. Collaboration usually involves regular meetings to align on goals, discuss technical constraints, and review progress. Effective communication and teamwork are key, as engineers may need to translate complex technical concepts for non-technical colleagues and incorporate feedback from different stakeholders. This cross-functional approach helps ensure that projects are delivered efficiently and meet all necessary standards.

What is the difference between Engineer vs Technician?

AspectEngineerTechnician
Required CredentialsBachelor's degree in engineering or related fieldTechnical diploma or associate degree
Work EnvironmentDesign, planning, analysis, project managementInstallation, maintenance, troubleshooting
Industry UsageDesign firms, manufacturing, constructionField service, manufacturing plants, maintenance teams
Common Search/ComparisonEngineer vs Technician

Engineers typically hold a bachelor's degree and focus on designing, analyzing, and managing projects. Technicians usually have technical diplomas and handle hands-on installation, maintenance, and troubleshooting. While engineers plan and oversee, technicians implement and support. Both roles are essential in engineering projects, but they differ in education, responsibilities, and work environment.

What are 10 engineering jobs?

Engineering encompasses a wide range of roles including civil engineer, mechanical engineer, electrical engineer, software engineer, chemical engineer, aerospace engineer, industrial engineer, environmental engineer, biomedical engineer, and petroleum engineer. These jobs often require specific technical skills, relevant certifications, and proficiency with industry tools and software. The roles vary by industry and specialization, offering diverse career paths for engineering professionals.

What are 10 types of engineers?

Engineers specialize in various fields, including civil, mechanical, electrical, chemical, software, aerospace, biomedical, environmental, industrial, and nuclear engineering. Each type focuses on different industries and uses specific skills, tools, and certifications to solve technical problems. The choice of engineering discipline depends on interests and career goals.

What kind of jobs do engineers do?

Engineers design, develop, and test systems, structures, or products across various fields such as civil, mechanical, electrical, software, and aerospace engineering. They often work in offices, labs, or construction sites, using technical skills, mathematics, and industry standards to solve problems and improve technology.

Job description

We are seeking a Robotics & Autonomy Engineer to develop, integrate, and maintain autonomy capabilities on UAV platforms built around the PX4 and ArduPilot stacks. This is a full-time role on our engineering team, working across a range of client projects — so the day-to-day emphasizes hands-on integration, debugging, and real-world flight validation more than ground-up design ownership. You'll work across the full UAV stack, from embedded flight software and state estimation through mission logic and system integration, with a strong focus on reliability and practical field performance.

This position suits someone who enjoys both software development and hands-on hardware work, and who's comfortable owning problems across shifting project contexts. The ideal candidate brings solid robotics and autonomy fundamentals — estimation, controls, and coordinate frames — and is eager to grow deep expertise in the PX4 autopilot stack, including VIO, map matching, and GPS-denied navigation.

MUST HAVE PERMANENT RESIDENCE IN US Responsibilities
  • Develop and modify PX4 or ArduPilot firmware to support new autonomy features and system capabilities
  • Implement mission logic, flight behaviors, and MAVLink integrations
  • Integrate sensors, cameras, radios, and payloads into UAV platforms
  • Tune and analyze estimation and control performance (EKF/Kalman filtering, PID loops) across platforms
  • Conduct flight testing and validate autonomous behaviors in real-world conditions
  • Analyze flight logs and telemetry to diagnose and resolve issues
  • Debug problems across the UAV stack including firmware, networking, hardware, and companion computers
  • Collaborate with engineers to design robust UAV architectures and workflows
  • Document system behavior, debugging results, and design decisions
Required Qualifications
  • Strong robotics/autonomy fundamentals: coordinate frame transformations, state estimation (Kalman filtering / sensor fusion), and PID control analysis
  • Strong C++ or C programming skills
  • Experience with PX4 or ArduPilot — or demonstrated ability to ramp quickly on a complex embedded autopilot codebase
  • Experience flying and testing UAV or robotic platforms
  • Familiarity with MAVLink, flight logs, and autopilot configuration
  • Experience debugging complex software and hardware interactions
  • Ability to work independently and take ownership of engineering tasks across multiple projects
  • Strong problem-solving skills and practical engineering judgment
Preferred Qualifications
  • Experience with ROS/ROS 2 and Nav2
  • Experience with visual-inertial odometry (VIO), map matching, or GPS-denied navigation
  • Experience building or configuring drones from components
  • Familiarity with companion computers (Linux), MAVSDK, or ROS
  • Experience integrating sensors such as LiDAR, cameras, or GPS systems
  • Experience with embedded systems or hardware debugging
  • Experience analyzing flight logs and tuning flight controllers
  • Personal robotics, UAV, or embedded systems projects
What We Value
  • Engineers who build and experiment outside of work
  • Strong ownership and accountability for outcomes
  • Practical, hands‑on problem solving
  • Clear communication and collaboration within small teams
  • Curiosity and continuous learning
