Call Service From Hangfire

I have a structured project with DDD layers, where Hangfire is used to send asynchronous emails. At the service call point, the following error is generated:

System.InvalidOperationException HResult=0x80131509 Message=The request lifetime scope cannot be created because the HttpContext is not available. Source=Autofac.Integration.Mvc StackTrace: at Autofac.Integration.Mvc.RequestLifetimeScopeProvider.GetLifetimeScope(Action`1 configurationAction) at Autofac.Integration.Mvc.AutofacDependencyResolver.get_RequestLifetimeScope() at Autofac.Integration.Mvc.AutofacDependencyResolver.GetService(Type serviceType) at System.Web.Mvc.DependencyResolverExtensions.GetService[TService](IDependencyResolver resolver) at Track.Web.Job.DoWork() in I:...\Jobs\Job.cs:line 19

How resolve it ?

This is my Source :

// Startup.cs
[assembly: OwinStartup(typeof(MyWeb.Startup))]

namespace MyWeb
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            GlobalConfiguration.Configuration.UseSqlServerStorage(
                "MyEntities",
                new SqlServerStorageOptions
                {
                    PrepareSchemaIfNecessary = false,
                    QueuePollInterval = TimeSpan.FromSeconds(1)
                }).UseFilter(new LogFailureAttribute());

            BackgroundJob.Enqueue(() => Console.WriteLine("Getting Started with HangFire!"));

            RecurringJob.AddOrUpdate(() => new Job().DoWork(), Cron.Minutely);

            app.UseHangfireDashboard();
            app.UseHangfireServer();
        }
    }
}

// Bootstrapper.cs
namespace MyWeb
{
    public class Bootstrapper
    {
        public static void Run()
        {
            SetAutofacContainer();
            AutoMapperConfiguration.Configure();
        }

        private static void SetAutofacContainer()
        {
            var builder = new ContainerBuilder();
            builder.RegisterControllers(Assembly.GetExecutingAssembly());
            builder.RegisterType<UnitOfWork>().As<IUnitOfWork>().InstancePerRequest();
            builder.RegisterType<DbFactory>().As<IDbFactory>().InstancePerRequest();


            // Repositories
            builder.RegisterAssemblyTypes(typeof(ProjectRepository).Assembly).Where(t => t.Name.EndsWith("Repository")).AsImplementedInterfaces().InstancePerRequest();

            // Services
            builder.RegisterAssemblyTypes(typeof(ProjectService).Assembly).Where(t => t.Name.EndsWith("Service")).AsImplementedInterfaces().InstancePerRequest();

            IContainer container = builder.Build();
            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
        }
    }
}

// Job.cs
namespace MyWeb
{
    public class Job
    {
        public void DoWork()
        {
            IProjectService _projectService = DependencyResolver.Current.GetService<IProjectService>(); // ERROR 
        }
    }
}
